United Airlines
United Airlines is one of the four largest U.S. carriers and a founding member of the Star Alliance, operating a global network from hubs in Newark, Chicago O'Hare, Denver, Houston, Los Angeles, San Francisco, and Washington Dulles. Formed through the 2010 merger of United and Continental Airlines, it serves over 200 domestic and international destinations and carried more passengers than any year in its history in 2024.

Score History
Timeline events are AI-curated from public reporting. Score trajectory is derived from documented events.
The Civil Aeronautics Act of 1938 put fares, routes and market entry under federal control, and United grew into one of the nation's largest carriers under that regime, absorbing Capital Airlines in 1961. Tickets bundled meals, bags and roomier seats, and competition was limited by regulators rather than by United's own conduct: United was among the trunk carriers grandfathered into route certificates in 1939, a protected class the CAB regulated largely in their interests.
The Airline Deregulation Act freed fares and routes, and United built fortress hubs such as Chicago O'Hare, where it opened Terminal 1 in 1987. It launched Mileage Plus in 1981 and later made miles expire, while its Apollo reservation system listed United flights first until the CAB banned display bias in 1984. Pilots struck for 29 days in 1985 over a two-tier pay scale, and in 1992 the DOJ charged United and seven other airlines with coordinating fares through ATPCO.
Employees took 55% of United in exchange for $4.8 billion in wage concessions, but the plan excluded flight attendants and a pilot slowdown in summer 2000 still cancelled more than 25,000 flights. United co-founded Star Alliance in 1997, gaining antitrust-immune international coordination, bid for US Airways until the DOJ threatened to sue, and cut travel agent commissions from 1997 until they were eliminated in 2002. Economy Plus began separating legroom from the standard ticket.
After the post-9/11 slump and a rejected federal loan request, UAL filed the largest airline bankruptcy in U.S. history. The court let United terminate four pension plans, a $9.8 billion default and the largest in U.S. history, and United exited in 2006 with about 30% fewer employees and more than $3 billion a year in lower labor costs. It also pressed regional partners for concessions while under court protection, and in 2006 imposed a $3.50 per-segment fee on travel agents booking through most GDS products, without guaranteeing them its full fares.
With fuel at record prices, United followed American in charging $15 for a first checked bag on top of a $25 second-bag fee, and raised its job-cut target to 7,000 while retiring 100 aircraft. The viral 2009 'United Breaks Guitars' video captured its reputation for poor service. Ancillary fees became a permanent part of the fare.
The all-stock merger with Continental, valued at about $3 billion, created the world's largest airline and added Newark and Houston hubs; by 2015 United held 73% of Newark slots and the DOJ sued to stop it buying more. Integration brought a chaotic 2012 reservation cutover, Million Miler lawsuits, spend-based elite qualification and revenue-based earning, while United raised change fees to $200 without announcement in 2013 and began the buybacks that reached $8.57 billion by 2019. CEO Jeff Smisek resigned in 2015 amid a Port Authority corruption probe, and the DOT fined United $2.75 million in 2016 for disability and tarmac-delay violations.
United launched Basic Economy, barring domestic passengers from the overhead bin, seat selection and changes, raised premium award prices on its own flights in November 2017, and in December 2017 authorized another $3 billion in buybacks, about 17% of its market value. The April 2017 dragging of David Dao and the 2018 death of a puppy placed in an overhead bin became symbols of airline mistreatment; a MapLight review then found United had spent more than $41 million over the prior decade lobbying, often against passenger protections, and its trade group won a delay of fee-disclosure rules. United abolished its published award chart in November 2019.
United took about $5 billion in CARES Act payroll support, cut hours for 15,000 employees and furloughed 13,432 workers when the aid lapsed in October 2020; it also narrowed its refund definitions in a way the DOT's guidance called unfair when applied to existing tickets. It permanently dropped most domestic change fees in August 2020. In the recovery, pilots won a rich 2023 contract while flight attendants went years without a raise, CEO Scott Kirby's pay climbed as CARES limits expired, United led airline lobbying in 2023, and the FAA stepped up oversight after a string of 2024 safety incidents.
A $1.5 billion buyback, United's first since the pandemic bailout, opened a phase of record revenue and rising monetization: MileagePlus devaluations in 2025, earning cuts for members without a United card from April 2026, a $10 bag-fee increase and new 'basic' business-class fares. The industry lawsuit against the DOT's fee-disclosure rule succeeded in February 2026. Flight attendants ratified a contract with 31% raises in May 2026 and free Starlink Wi-Fi lifted satisfaction, but mechanics rejected a tentative deal in September 2026 and United kept pressing for hub and merger advantage.
Alternatives
Especially relevant for United customers on the West Coast: Alaska competes directly with United in San Francisco, Los Angeles, and Seattle, ranked above United in the 2025 ACSI airline customer-satisfaction index and level with it in 2026. Its loyalty program partners with American Airlines, giving more domestic flexibility. Its long-haul international network is far smaller than United's.
Ranked first in the 2025 ACSI airline customer-satisfaction index and still above United in 2026, and charges no change fees on its Choice fares, though its cheapest Basic fares have been non-changeable since 2025 and it ended free checked bags in May 2025 ($35/$45). Particularly relevant for United customers in Denver and Chicago, where Southwest has substantial competing service. The catch: no long-haul international service, so it won't cover United's trans-Pacific and Star Alliance routes.
The most practical legacy-carrier switch for most United customers: Delta topped the 2026 ACSI airline customer-satisfaction index, well ahead of United, and the two carriers overlap on many routes and in premium and international service. The catch: if you're based at a United fortress hub (Newark, Chicago O'Hare, Houston Intercontinental, Denver, Washington Dulles), Delta may have fewer or less convenient options.

Dimension History
Timeline (101 events)
Civil Aeronautics Act establishes federal airline regulation
Congress passed the Civil Aeronautics Act of 1938, the nation's first comprehensive commercial airline regulatory regime, authorizing the federal government to regulate fares, routes, and safety. From 1940 the Civil Aeronautics Board (CAB) set prices, awarded routes, and specified flight frequencies between city pairs for four decades. Established carriers such as United operated within this system, while airlines seeking new routes or discount fares routinely faced years of regulatory roadblocks. United was among the 16 trunk carriers grandfathered in 1939 into certificates for the routes they already flew, a protected class the CAB regulated largely in their interests.
Airline Deregulation Act signed into law
President Carter signed the Airline Deregulation Act on October 24, 1978, removing federal control over fares, routes, and market entry. Legacy carriers including United shifted to hub-and-spoke systems; the Smithsonian notes that where one airline dominated a hub, the lack of competition often led to higher fares. Many carriers that could not weather the new competition, including Braniff and Eastern, were forced into bankruptcy and extinction.
Deregulation-era competition begins long shrinkage of economy legroom
Deregulation opened fare competition, and airlines began packing more seats into their cabins. According to seat-size analysis cited by Popular Science, American, Delta, Southwest, and United have each lost between 2 and 5 inches of legroom and about 2 inches of seat width since the 1980s, with average legroom on those carriers now about 31 inches versus roughly 35 inches in the late 20th century. Airlines now sell extra-legroom tiers such as United's Economy Plus while advertising rock-bottom base fares.
United launches Mileage Plus frequent flyer program
United unveiled its Mileage Plus program one week after American Airlines launched AAdvantage in May 1981, making it one of the first airline loyalty programs. The program awarded miles based on distance flown and laid the foundation for decades of customer lock-in, later becoming one of United's most valuable financial assets and its most powerful switching-cost mechanism. When United borrowed against the program in June 2020, it valued MileagePlus at $21.9 billion (12 times 2019 EBITDA).
CAB bans Apollo CRS display bias after antitrust complaints
The Civil Aeronautics Board issued final rules on July 27, 1984 banning display bias in computer reservation systems, after United's Apollo and American's SABRE were found to list their owners' flights at the top of the first screen while the toughest competitors were pushed to the bottom of the last screen. United issued Apollo contracts with a 95% exclusivity rule to discourage travel agents from using rival systems. The United and American systems together accounted for 80% of automated travel agency locations and 40-50% of all travel agency sales. The rules followed petitions from travel agents and twelve subscriber airlines; United challenged them in court, and airlines later brought antitrust suits over CRS practices.
United pilots strike for 29 days over B-scale pay
United's roughly 5,000 pilots went on a 29-day strike beginning May 17, 1985, after CEO Richard Ferris demanded a two-tier 'B-scale' that would pay newly hired pilots less. Ferris threatened to hire permanent replacements and had trained 570 new second officers in advance, but only about 6% of pilots crossed the line. Under shareholder and lender pressure he settled for a five-year B-scale. The dispute foreshadowed the recurring labor conflicts that would define United's next four decades.
United opens Terminal 1 at O'Hare, cementing fortress hub
United completed its dedicated Terminal 1 at Chicago O'Hare in 1987 as part of the airport's $1 billion redevelopment, designed to optimize hub-and-spoke connections for its growing network. O'Hare operations were capped under the FAA's High Density Rule from 1969 until Congress ended it there effective July 2002, limiting new-entrant access to the airport where United was building its largest hub.
Mileage Plus introduces expiring miles, building on 1983 Premier elite tier
United introduced the idea of airline elite status with its Premier tier in 1983, and in 1989 introduced the concept of miles that expired, which became the industry standard and created a use-it-or-lose-it urgency to keep flying United. Elite benefits such as upgrades and priority service made switching carriers increasingly costly for frequent travelers.
DOJ charges United and seven airlines with price fixing via ATPCO
The Department of Justice filed suit alleging that United, American, Delta, Northwest, Continental, USAir, TWA, and Alaska Airlines used the Airline Tariff Publishing Company's fare dissemination system to coordinate fare increases and eliminate discounts from at least April 1988. United and USAir settled at filing through a consent decree restricting fare signaling practices. When the remaining airlines settled on March 17, 1994, DOJ said the system had been used to raise ticket costs by perhaps more than a billion dollars between 1988 and 1992.
Employees acquire 55% of United via ESOP
United's stockholders approved transferring 55% of the company to employees in exchange for $4.8 billion in wage concessions, making United the largest employee-owned company in America. The plan was marketed as a labor-management partnership but excluded flight attendants and created deep workforce divisions between ESOP and non-ESOP employees.
United co-founds Star Alliance with four airlines
United, Lufthansa, Air Canada, Scandinavian Airlines, and Thai Airways launched Star Alliance, the world's first global airline alliance. The DOT subsequently granted antitrust immunity to alliance members, enabling coordinated pricing and capacity management on international routes — a legal framework that reduced competitive pressure across the Atlantic and Pacific.
United cuts travel agent commissions to 8%
United reduced travel agent commissions from 10% to 8% of ticket price, following the industry trend toward disintermediation. This was the opening move in a five-year campaign that ended with the complete elimination of base commissions in March 2002, fundamentally restructuring the distribution channel to favor airline-controlled booking.
United introduces Economy Plus paid seating
United debuted Economy Plus in 1999, an early extra-legroom section within economy that later became a paid upsell, unbundling seat comfort from the base ticket. Economy Plus seats today offer roughly 33-38 inches of pitch versus 30-31 inches in standard economy. The model was widely copied across the industry and became a significant ancillary revenue stream.
United bids $12.3B for US Airways; DOJ threatens antitrust suit
United announced a deal to acquire US Airways for $4.3 billion in cash, a transaction valued at about $11.6 billion including assumed debt and aircraft leases, that would have created the world's largest airline and given United a monopoly or duopoly on nonstop service on over 30 routes where consumers spend over $1.6 billion annually. The DOJ and several state attorneys general said they would sue, citing harm on hub-to-hub routes such as those touching Philadelphia and on nonstop markets at Washington and Baltimore. United abandoned the acquisition in July 2001, but the episode showed United's intent to consolidate the industry, which it achieved with the 2010 Continental merger.
Pilots stage summer slowdown, stranding passengers
United's pilots, who held a significant ownership stake through the ESOP, conducted a work-to-rule campaign during stalled contract talks in the summer of 2000. United cancelled over 25,000 flights that summer and delayed many more, carrying one million fewer passengers in August 2000 than a year earlier, demonstrating the ESOP's failure to resolve labor-management tensions.
United eliminates all travel agent base commissions
In March 2002 United and the other major carriers ended the flat base commissions they had traditionally paid travel agents, completing a five-year process of dismantling the independent distribution channel. GAO found that between 1999 and 2002 the share of tickets booked online grew from 7% to 30%, and that airlines cut payments to travel agencies by 57% over the same period, helping them bypass agents.
United files largest airline bankruptcy in US history
UAL Corporation filed for Chapter 11 bankruptcy protection on December 9, 2002, with $22.8 billion in assets, one of the largest bankruptcies in U.S. history, after the government's loan board rejected its request for aid. The filing followed the post-9/11 traffic collapse and the costly 2000 labor disputes. The restructuring lasted 1,150 days, cut employees from 100,000 before 9/11 to 62,000 in 2004, and ended the employee pension plans.
United pressures regional partners for concessions during bankruptcy
While operating under Chapter 11 bankruptcy protection, United leveraged its financial position to pressure regional carrier partners for reduced fees under capacity purchase agreements. Atlantic Coast Airlines canceled its United Express contract in 2004, attempting to relaunch as low-cost carrier Independence Air, but ceased operations just 18 months later — demonstrating the dependency that capacity purchase agreements created. United replaced departing partners with new contracts with GoJet, Colgan Air, and Republic Airways subsidiaries, maintaining its regional network while extracting better terms from carriers that had no viable alternative to feed traffic.
Court approves largest pension default in US history
Bankruptcy Judge Eugene Wedoff approved United's plan to terminate four employee pension plans covering pilots, flight attendants, mechanics, and ground workers. The $9.8 billion pension default was the largest in U.S. history. Pilots faced pension cuts of up to 50%, while lower-paid workers lost up to 20%. The PBGC capped individual payments at approximately $45,000 per year.
United exits bankruptcy after 1,150 days
United emerged from the longest and costliest airline restructuring in history after 1,150 days, with about 30% fewer employees (58,000), 20% fewer aircraft (460), and annual labor costs reduced by more than $3 billion after two steep pay cuts and the elimination of defined-benefit pensions. Employee-held ESOP shares were wiped out, while a new stock plan gave 8% of shares to top executives, angering unions.
United imposes $3.50 per-segment fee on travel agents using most GDSs
Days after American did the same, United told travel agents that bookings made through most global distribution systems would carry a $3.50 per-segment fee from September 1, 2006, unless they used specific discounted GDS products. Unlike American, United said agents paying the fee were not guaranteed access to its full fare content.
DOT fines United $75,000 for disability access violations
The DOT issued a consent order finding United violated 14 CFR Part 382 implementing the Air Carrier Access Act, including failing to provide proper stowage for a passenger's folding wheelchair, and assessed a $75,000 compromise civil penalty. A February 2007 order separately found United's website fare advertisements for its military discount program failed to disclose that the fares applied only to domestic travel.
United introduces first and second checked bag fees
Following American Airlines' lead, United announced a $15 fee for the first checked bag on tickets purchased from June 13, 2008, on top of the $25 second-bag fee, as record fuel prices drove carriers to pass costs to passengers. This marked the beginning of the airline unbundling era, transforming included services into ancillary revenue streams.
United cuts 7,000 jobs and 100 aircraft as fuel costs spike
Facing record jet fuel prices, United raised its job-elimination goal to 7,000 by the end of 2009, up from about 3,800, with the additional reductions coming from front-line workers. It retired 100 aircraft including all its 737s, cut fourth-quarter domestic capacity 16%, and reported a $2.73 billion second-quarter loss as its annual fuel bill rose by more than $3.5 billion. The cuts came two years after United emerged from bankruptcy, during which employees had already absorbed deep pay concessions.
"United Breaks Guitars" goes viral, exposing service failures
Canadian musician Dave Carroll released a YouTube video after United baggage handlers at Chicago O'Hare broke his $3,500 Taylor guitar and about nine months of negotiations for compensation went nowhere; United had told him he missed its 24-hour claim window. The video drew 150,000 views in a day, 5 million by mid-August 2009, and roughly 30 million by 2026, becoming a public relations humiliation for United. Time magazine named it No. 7 on its Top 10 Viral Videos of 2009. United's belated $3,000 compensation offer, which it donated to a jazz institute as a goodwill gesture, did not undo the damage.
United and Continental announce all-stock merger
United and Continental Airlines announced a merger of equals, an all-stock deal valued at about $3 billion, creating the world's largest airline. In August 2010 the DOJ closed its investigation after the carriers agreed to transfer takeoff and landing slots and other assets at Newark to Southwest Airlines. Research later found that fares on formerly competitive nonstop routes increased 7.8% post-merger.
Reservation system merger causes chaos; DOT later fines United over delayed refunds
United migrated all United and Continental reservations to a single passenger service system on March 3, 2012, which United itself called the largest undertaking of its kind in airline history. The cutover produced a backlog and system problems, and between March and May 2012 United failed to process more than 9,000 refund requests on time. The DOT later assessed a $350,000 civil penalty for the refund failures and inaccurate reporting.
Million Milers sue United over merger-era benefit downgrades
Frequent flyer George Lagen filed a class action lawsuit alleging United 'immorally' rescinded lifetime benefits promised to pre-merger Million Mile Flyers. Before the Continental merger, Million Milers were guaranteed lifetime Premier Executive status with three systemwide upgrades, two regional upgrades per year, and 100% bonus miles. After the merger integration, members found their 1 million miles only qualified for second-tier status. The litigation exposed how mergers enabled airlines to renegotiate loyalty promises unilaterally, deepening lock-in — members had spent years accumulating status only to have it devalued.
United raises change fees to $200 domestic, $300 international without announcement
United quietly raised the change fee on most non-refundable fares by $50, to $200 for domestic and $300 for international itineraries, for tickets issued on or after April 18, 2013. Frequent flyers discovered the increase on FlyerTalk before United confirmed it, saying it incurs costs when travelers do not fly in reserved seats.
United introduces Premier Qualifying Dollars, tying status to spend
United announced that starting in 2014, earning Premier elite status would require a minimum annual spend in Premier Qualifying Dollars (PQD) in addition to miles or segments: $2,500 for Silver, $5,000 for Gold, $7,500 for Platinum, and $10,000 for 1K. The PQD requirement could be waived for Silver through Platinum by spending $25,000 a year on a Chase co-branded MileagePlus card, tying affordable status maintenance to credit card ownership.
United begins massive stock buyback program
United launched a sustained share repurchase program, ultimately spending $8.57 billion buying back stock between 2014 and 2019, including about $2.6 billion in 2016 alone. Bloomberg found the biggest U.S. airlines spent 96% of their free cash flow over the decade on buybacks, with United using 80% of its free cash flow for repurchases, leaving thin reserves when the pandemic struck.
United opposes DOT fee disclosure rules
United argued against proposed DOT rules mandating better disclosure of fees charged to airline consumers, telling regulators that 'every ticket, of course, guarantees a passenger a seat on the plane.' The airline spent $7.26 million during a two-year congressional session fighting legislation including measures for minimum seat sizes and family seating requirements.
United shifts to revenue-based mileage earning, deepening credit card lock-in
Effective March 1, 2015, United changed MileagePlus from distance-based to revenue-based earning: general members now earned 5 miles per dollar spent instead of 1 mile per mile flown. The change penalized passengers who flew long distances on discounted fares while rewarding high spenders — particularly co-branded Chase credit card holders whose PQD waiver required $25,000 in annual card spend. The new Premier qualifying dollar (PQD) requirement, introduced in 2014, meant earning elite status required both flying and spending, creating a two-dimensional lock-in that tied travelers to both United flights and United credit card products.
CEO Jeff Smisek resigns amid Port Authority corruption probe
CEO Jeff Smisek and other senior executives left United amid a federal investigation into whether the airline restored a Newark-Columbia, S.C. flight near the weekend home of Port Authority chairman David Samson to win favor on Newark airport projects. Smisek denied wrongdoing, yet Bloomberg estimated he departed $28.6 million richer, including lifetime flight and parking perks.
DOJ files antitrust suit over Newark slot monopolization
The Department of Justice sued to block United's purchase of 24 takeoff and landing slots from Delta at Newark, alleging it would strengthen United's monopoly position. United already held 73% of Newark's 902 slots — more than 10 times its closest competitor — while grounding up to 82 slots daily and charging among the highest fares in the country.
DOT fines United $2.75 million for disability and tarmac-delay violations
The DOT fined United $2.75 million for failing to give passengers with disabilities prompt assistance at Houston, Chicago O'Hare, Denver, Newark and Dulles, for failing to return wheelchairs and other mobility aids promptly and undamaged, and for violating the long-tarmac-delay rule. The investigation followed a significant increase in disability complaints in 2014.
United abandons Newark slot purchase after DOJ antitrust suit
United and Delta terminated the agreement for United to buy 24 Newark slots, which the DOJ had sued to block in November 2015, after the FAA said it would lift slot controls at Newark. The DOJ said United held 902 slots, 73% of the airport's total, and grounded more slots on a given day than competitors had the option to fly.
United launches Basic Economy with overhead bin ban
United began selling Basic Economy fares in 2017 that restricted domestic passengers to a single personal item under the seat, prohibited overhead bin use, denied seat assignments, and barred flight changes, with passengers boarding last. The product stripped the ticket to bare transportation access to compete with discount airlines. United printed 'Basic Economy' in large letters on physical tickets and made mobile boarding passes orange so gate agents would not let these passengers board out of turn.
Passenger David Dao violently dragged from Flight 3411
Airport security officers forcibly removed physician David Dao, 69, from United Flight 3411 at Chicago O'Hare after he refused to give up his seat for crew members; they struck his face against an armrest and dragged him, bloodied and apparently unconscious, down the aisle. He suffered a concussion, a broken nose and the loss of two teeth. The incident went viral worldwide and United's market value fell by about $1 billion. CEO Oscar Munoz initially defended employees in an internal memo that described Dao as 'disruptive' and 'belligerent' before issuing a full apology. Dao reached a confidential settlement with United later that month.
MapLight: United spent $41 million over a decade lobbying, often against passenger protections
A MapLight/International Business Times review of lobbying records found United had spent more than $41 million over the prior decade lobbying the federal government, often against consumer-friendly causes, including $7.26 million in the last two-year session of Congress fighting bills on minimum seat sizes, family seating and lavatory fees. The review noted United was a member of a lobbying group that successfully pressed the Trump administration to delay proposed rules requiring airlines to disclose their fees more transparently.
Airline lobbying surges after Dao incident as FAA bill adds passenger protections
After the April 2017 Dao video, Airlines for America, which represents United, spent more than $2 million on federal lobbying in the second quarter of 2017, up nearly 19% from the first quarter, while Congress drafted FAA reauthorization bills with new consumer protections. The group opposed a Senate provision barring baggage or cancellation fees the DOT deemed unreasonable.
United raises premium award prices on its own flights
Changes announced in June 2017 took effect November 1, raising saver business-class award prices on United-operated flights to many regions (for example Australia/New Zealand from 70,000 to 80,000 miles one-way) and on premium transcontinental routes from 25,000 to 35,000 miles one-way, while replacing standard awards with demand-based 'Everyday Awards' that could cost more.
United authorizes new $3 billion share buyback
United's parent authorized a new $3 billion share repurchase program, about 17% of its market capitalization, as it was completing a $2 billion program authorized in July 2016.
Puppy dies after United flight attendant has carrier placed in overhead bin
A French bulldog puppy died on a Houston-New York United flight after a flight attendant insisted its carrier be put in an overhead bin. United apologized, settled with the family in May 2018 and scaled back its PetSafe program, after other pet mishaps including a dog flown to Japan by mistake.
United threatens collections and bans over hidden city ticketing
United escalated enforcement against hidden city ticketing (booking a connecting itinerary but skipping the last leg), sending passengers letters demanding payment of fare differences and threatening to send the claims to collection agencies, terminate MileagePlus memberships, and refuse future transport. A 2024 Fideres analysis argued that the big four airlines' skiplagging restrictions use market power around hubs to protect supra-competitive prices on routes where they hold a monopoly, raising antitrust questions.
United-backed venture buys regional carrier ExpressJet
ManaAir, a joint venture in which United held a 49.9% stake, agreed to buy ExpressJet from SkyWest in a $70 million deal that closed in early 2019. The stake was seen as giving United more negotiating power over the third-party regional airlines that fly most of the United Express network.
United abolishes fixed MileagePlus award chart
United eliminated its published award redemption chart, replacing it with fully dynamic award pricing beginning November 15, 2019. Award costs now vary with demand, removing the last transparent reference point members could use to value their accumulated miles.
United receives $5 billion in CARES Act bailout funds
United confirmed it expected to receive about $5.0 billion through the CARES Act Payroll Support Program, roughly $3.5 billion as a direct grant and $1.5 billion as a low-interest loan, plus warrants for the government. The aid followed $8.57 billion in stock buybacks from 2014-2019 and came with restrictions on buybacks, dividends, and executive pay.
United uses CARES Act loophole to reduce employee pay
Despite receiving billions in taxpayer-funded payroll support, United announced it would cut hours for 15,000 employees, reducing their pay while technically avoiding furloughs. Senator Josh Hawley demanded United reverse the cuts or return its CARES Act money.
United narrows refund definitions as DOT warns retroactive changes are unfair
In spring 2020 United redefined a significant schedule change as a move of six hours or more and treated a flight as cancelled only if it could not rebook the passenger, after previously honoring refunds for changes of two hours or more. DOT guidance said denying refunds under policies stricter than those in force when a ticket was bought would be an unfair and deceptive practice.
Scott Kirby becomes CEO, replacing Oscar Munoz
Scott Kirby assumed the CEO role at United's annual meeting, succeeding Oscar Munoz who moved to executive chairman. Kirby, who had been president since August 2016, would go on to earn $33.9 million in total compensation by 2024 — a 380:1 ratio to the median worker salary and the highest among major U.S. airline CEOs.
United ends ExpressJet contract, dooming its sole-customer regional partner
United said it would end its capacity purchase agreement with ExpressJet, which flew only for United, and consolidate its 50-seat jet flying with CommutAir. United held a minority stake in ExpressJet's parent; the regional carrier's CEO had warned that its private-label model left it no cushion for the pandemic.
United permanently eliminates most domestic change fees
United permanently dropped change fees on standard Economy and premium tickets for travel within the U.S. and announced free same-day standby from 2021. Basic Economy tickets were excluded. CEO Scott Kirby said removing the fee was customers' top request.
United furloughs 13,432 workers as payroll aid expires
United sent involuntary furlough notices to 13,432 employees, about half in inflight services, as the CARES Act Payroll Support Program's bar on layoffs expired. United had received roughly $5 billion in payroll support.
United mandates COVID-19 vaccination, fires over 200 employees
United became the first major U.S. airline to require COVID-19 vaccination for all U.S. employees, with a late-September 2021 deadline. More than 96% of the 67,000-person U.S. workforce complied, but 593 employees faced termination and roughly 200 were ultimately fired. About 2,000 employees sought religious or medical exemptions; United said those granted exemptions would be placed on unpaid leave, prompting a federal lawsuit. A Fifth Circuit panel found in February 2022 that plaintiffs faced 'ongoing coercion,' and United let exempt workers return in March 2022.
DOT fines United $1.9M for tarmac delay violations
The DOT fined United $1.9 million for 25 flights between December 2015 and February 2021 that remained on the tarmac beyond the legal limit without offering passengers the option to deplane. Investigators found United failed to provide 'sufficient resources' for its tarmac delay contingency plan and in some cases failed to inform passengers they could leave aircraft at the gate.
United union coalition forms for coordinated bargaining
Workers and unions across United Airlines announced the United Airlines Union Coalition to coordinate bargaining, as four of the five unions were in contract negotiations at the same time. The coalition brought together ALPA (pilots), AFA-CWA (flight attendants), IAM (ramp, customer service and other workers), PAFCA (dispatchers), and the Teamsters (about 10,000 technicians).
Seat selection revenue reaches $1.3 billion
A Senate probe revealed United collected $1.3 billion in seat selection fees in 2023, surpassing its $1.2 billion in bag fee revenue for the first time. The combined total of seat selection fees across five major U.S. airlines hit $3 billion in 2023, up from $2 billion in 2018. United's total ancillary revenue would reach $4.5 billion by 2024.
United raises Europe award prices 33-46% without notice
United raised MileagePlus award prices to and from Europe without notice, with partner business class awards jumping to 102,400 miles one-way and partner economy awards rising from 30,000 to 43,900 miles (46%). Within 24 hours United walked the increase back partially, to 88,000 miles in business and 40,000 in economy, but the episode showed how the absence of a published award chart lets United reprice members' miles at will.
United pilots ratify contract with up to 40% raises while flight attendants wait
United pilots ratified a new contract by 82% that the union valued at around $10 billion, including raises of up to 40% over four years. The pilot deal contrasted with the flight attendants' situation: their last raise came in 2020 and they remained without a new contract, illustrating how settlement timing tracked each work group's leverage.
United leads airline lobbying with $7.5 million through Q3 2023
United spent $7.5 million on federal lobbying in the first three quarters of 2023, more than any other airline and more than the Airlines for America trade group ($4.4 million), as Congress debated FAA reauthorization, including proposals to add long-distance slots at Washington National Airport.

United raised domestic checked bag fees by $5, to $35 prepaid online or $40 at the airport for the first bag and $45/$50 for the second, its first bag fee increase since 2020, continuing a pattern of increases that began with $15 in 2008. By 2024 United, like American and Delta, was collecting more than $1 billion a year in checked bag fees, according to BTS data.
FAA lets United restart certification work after stepped-up safety review
The FAA had increased oversight of United in March 2024 after incidents including a 777 losing a tire after takeoff and a missing panel on a 737, blocking new routes such as Faro, Portugal. In May United said it could restart certification activities, while the FAA said its review was ongoing.
Judge upholds OSHA citation for worker foot amputation
A federal administrative law judge affirmed OSHA's citation and $14,502 penalty, the maximum allowed at the time, against United for a November 2021 incident at Newark where a 737's tire crushed a technician's foot, leading to amputation of five toes. Investigators found United failed to follow its own policies for towing aircraft safely. United filed a petition seeking to appeal the decision.
ARC data broker revealed selling passenger records to CBP
The Airlines Reporting Corporation, a data broker co-owned by United and other major airlines, was revealed to have been selling passenger travel records to U.S. Customs and Border Protection under a contract that began in June 2024. ARC's database contained more than one billion records spanning 39 months of travel, including names, itineraries, and financial details, and ARC instructed CBP not to disclose the data source.
Big Four consolidation leaves four carriers with about two-thirds of domestic market
The consolidation wave that reduced the major U.S. airlines to four, through the Delta-Northwest (2008), United-Continental (2010), Southwest-AirTran (2011), and American-US Airways (2013) mergers, left American, Delta, United, and Southwest with a combined 68% of the domestic market as of February 2024, with United at about 16%. High startup costs and slot constraints act as barriers to new entrants. Measured by seats, the concentration was higher: Alaska Air Group's 2018 annual report noted that four large carriers represented over 80% of total domestic seats.
Airlines for America blocks DOT junk fee transparency rule
A federal appeals court blocked the DOT's junk fee transparency rule pending review after Airlines for America (of which United is a member) and several airlines sued. The rule would have required airlines to disclose baggage, change, and cancellation fees upfront at the point of sale; the DOT estimated consumers overpay about $543 million a year in fees they are surprised by.
United announces $1.5B buyback after $5B pandemic bailout
United's board authorized a $1.5 billion share buyback program — the first since receiving approximately $5 billion in CARES Act taxpayer funds during COVID.

Senate PSI report exposes airline seat and bag fee growth
The Senate Permanent Subcommittee on Investigations published 'The Sky's the Limit,' finding that American, Delta, United, Frontier, and Spirit collected $12.4 billion in seat fees between 2018 and 2023, rising from $2 billion to $3 billion a year. United charged as much as $319 for an extra-legroom seat in 2023, collected more from seat fees ($1.3 billion) than bag fees ($1.2 billion) that year, and did not show seat-fee prices until customers provided personal information. The report also found United could not produce a cost basis for its checked-bag fees.
United posts record $4.2 billion pre-tax earnings
United reported record fourth-quarter and full-year 2024 results with $4.2 billion in pre-tax earnings, outperforming expectations.

United raises credit card annual fees across portfolio
United and Chase overhauled the six United co-branded credit cards, raising annual fees across the portfolio (for example, the Explorer card from $95 to $150) while adding statement credits.

United cuts 35 daily Newark flights amid air-traffic control failures
After radar and communications outages at the Philadelphia facility that handles Newark traffic, runway construction and controller shortages produced hundreds of delays and cancellations, United cut 35 daily round trips from Newark. CEO Scott Kirby said the airport could not handle the number of scheduled flights.
Three MileagePlus devaluations eliminate remaining fixed pricing
United announced three devaluations at once: eliminating the Excursionist Perk, its limited free-stopover award benefit (August 21, 2025), ending instant upgrades at booking for Premier members on full-fare tickets (August 21, 2025), and hiding the MileagePlus Upgrade Award chart in favor of dynamically priced upgrades (November 24, 2025). The Excursionist Perk had itself been the concession United gave members when it eliminated free stopovers eight years earlier.
CEO Kirby floats JetBlue acquisition, settles for Blue Sky
After CEO Scott Kirby publicly mused in March 2025 about a JetBlue merger, United and JetBlue unveiled the Blue Sky partnership in May 2025, giving United access to JFK slots for up to seven daily round-trips from 2027 in exchange for Newark flight timings, plus reciprocal loyalty benefits. The DOT completed its review in July 2025, allowing the collaboration to proceed. In July 2025 Senator Richard Blumenthal wrote to both CEOs that he was 'extremely wary of any partnership that may harm full and fair airline competition,' particularly in the New York City area.
Flight attendants reject contract after four-year freeze
United flight attendants voted down a tentative agreement offering immediate raises of at least 26%, with 71% voting against on 92% turnout. Their last raise had come in 2020, and the union and airline had reached the tentative agreement in May 2025 after years of negotiations.
Weight-and-balance system failure grounds United flights nationwide
A failure in United's Unimatic weight-and-balance system prompted ground stops at its hubs, delaying more than 1,000 flights and cancelling hundreds from the evening of August 6 into the next morning.
United requires login to see MileagePlus award prices
From around August-September 2025, United began requiring travelers to sign in to their MileagePlus account before seeing any award availability or prices, which had previously been visible to guests.

The FAA extended its June 2025 order limiting Newark operations through October 24, 2026, raising the cap from 68 to 72 hourly operations, after carriers concurred with the proposal. United, the dominant carrier at Newark, supported the continued limits.
Airline-owned ARC ends program selling passenger records to government
The Airlines Reporting Corporation, a data broker co-owned by United and other airlines, told government customers its Travel Intelligence Program would end by the end of 2025. The program had sold warrantless access to passenger records to CBP, ICE, TSA and other agencies, and drew bipartisan criticism.
DOT withdraws passenger delay-compensation proposal
The DOT withdrew its December 2024 proposal to require compensation for significant flight disruptions, citing deregulatory executive orders. Earlier in 2025 Airlines for America, whose members include United, had asked the DOT to repeal a range of passenger protections including automatic refunds.

United slashes mileage earning up to 40% for non-cardholders
United announced that beginning April 2, 2026, general members without a United credit card would earn 3 miles per dollar instead of 5, a cut of up to 40%, while cardholders would earn more, and Basic Economy passengers without a card or elite status would earn no miles. Award pricing would also favor cardholders, with 10-15% discounts on award redemptions and expanded access to Polaris business class saver awards. The changes made MileagePlus earning and redemption value increasingly dependent on holding a co-branded Chase card.
Appeals court lets vaccine-mandate class action against United proceed

United and flight attendants reach preliminary contract deal
United and the Association of Flight Attendants-CWA reached a preliminary agreement on March 26, 2026, after crews had rejected a prior tentative agreement in July 2025. The deal followed more than four years without a raise (the contract had been amendable since August 2021) and set the stage for the first flight attendant pay increase in close to six years. United was the last major U.S. carrier with unionized crews to reach a post-COVID flight attendant deal.
MileagePlus earning cuts take effect
United's MileagePlus overhaul took effect April 2, 2026: general members without a United co-branded card now earn 3 miles per dollar instead of 5, Basic Economy passengers without a card or elite status earn zero miles, and cardholders receive 10-15% award discounts and expanded access to lowest-priced awards. The changes, announced in February 2026, deepen credit-card-tied lock-in.
United raises checked bag fees by $10
United raised first and second checked bag fees by $10 for travel in the U.S., Mexico, Canada and Latin America from April 3, 2026, making the first bag $45 prepaid or $50 within 24 hours of departure, citing jet fuel costs. Chase cardholders, Premier members, military and premium-cabin passengers still check a bag free.
United introduces Basic Business fares, first U.S. carrier to charge business seat fees
United launched a three-tier structure (Base, Standard, Flexible) for its Polaris business and Premium Plus cabins on long-haul international, transcontinental, and select Hawaii routes, becoming the first U.S. airline to add 'basic business' fares. Base Polaris passengers must pay to select a seat before check-in, get one free checked bag instead of two, lose Polaris Lounge access, and cannot change or refund tickets, extending the Basic Economy unbundling model into premium cabins. Base Polaris fares are also not eligible for paid upgrades to the Polaris Studio suites.
Kirby reportedly floats United-American merger to federal officials

United Flight 169 Boeing 767 strikes truck and light pole landing at Newark
United Flight 169, a Boeing 767 arriving from Venice, flew low over the New Jersey Turnpike on approach to Newark's Runway 29 and its landing gear struck a light pole and a tractor-trailer; the pole then struck a Jeep. None of the more than 200 passengers and 10 crew were injured; the truck driver suffered cuts from broken glass. The NTSB classified the event as an accident due to the extent of damage to the airplane, and United removed the crew from service during the investigation. The NTSB's preliminary report identified the aircraft as a Boeing 767-400ER and found it only 19 feet above the Turnpike and below the normal glide path, flown in wind gusts producing moderate turbulence.
United flight attendants ratify landmark five-year contract
United's nearly 30,000 flight attendants ratified a new contract by an 82% margin (88.85% turnout). The deal delivers a 31% average base-pay increase, first-ever boarding pay (an average 7-8% boost to compensation, addressing the long-standing unpaid-ground-time grievance), $741 million in retroactive pay, sit pay for disruptions over 2.5 hours, 10 weeks of paid maternity leave plus two weeks of paid parental and adoption leave, and expanded job security. It was the last major post-COVID flight attendant contract among U.S. carriers, meaning all of United's major work groups now hold ratified agreements. The contract took effect May 31, 2026, and also restricts red-eye flying; the union's United council said it 'sets a new standard for our profession.'
Judge lets 'windowless window seat' class action against United proceed
A federal judge in San Francisco denied United's motion to dismiss a proposed class action by passengers who paid for window seats that had no window, finding United's ticketing terms and booking screens did not disclose missing windows.

Starlink Wi-Fi passes 450 aircraft as United posts strong Q2
United said more than 450 aircraft offered free Starlink Wi-Fi, with nearly 1,000 expected by year-end, and that its Q2 on-time departure rate was its best since 2021, while revenue rose 16% despite about $2.3 billion in higher fuel costs.
FAA proposes $255,000 fine over flight attendant drug-testing lapse
The FAA proposed a $255,000 civil penalty, alleging United let a flight attendant it had rehired after a 2021 test refusal work 47 flights between May 2024 and July 2025 without the required substance-abuse evaluation and return-to-duty testing.

[Second regrade this cycle] 58→58 (current dimensions unchanged). Follow-up to restore-check. Moved (eras only): 'Bankruptcy & Pension Default' D2 4→5 (correction: restored 2006 $3.50 per-segment GDS fee with full fare content withheld, alongside 2004 regional concessions, puts the era at the top of the 4-5 band; era 33→34); 'Basic Economy & Buybacks' D10 6→7 (correction: restored MapLight $41M decade of lobbying often against passenger protections, plus the 2017 trade-group delay of fee-disclosure rules, reverses part of the earlier 8→6 cut made for lack of events; era 55→56). Did not move: current D2 stays 5 (the restored GDS fee is a 2006 event; the removed recent NDC/GDS surcharge claim stays removed and there is still no recent escalation against partners); D4 stays 6 everywhere ($21.9B MileagePlus valuation measures the program's worth to United, not added passenger lock-in; Nov 2017 premium award hikes fit the 2017-2020 era's existing 6 with the 2019 chart abolition; the airline guide's medium band still matches); D8 unchanged (grandfathered trunk-carrier protection was conferred by the CAB, not United's conduct, so CAB era stays 3; >80% seat concentration in 2018 is structural and fits the 2017-2020 era's 6; Blumenthal's Blue Sky letter is not an investigation, current stays 7); D10 current stays 7 and CAB era stays 2 (no United-specific lobbying record for the regulated era).

Others unchanged. Eras: first era re-dated 1978-01-01→1938-06-23 (Civil Aeronautics Act) and split at 1978-10-24 (Deregulation Act) → new 'Deregulated Hub Build-out'; 'Deregulation & ESOP' re-dated 1994-07-01→1994-07-12 and relabeled 'Employee Ownership Experiment'; Bankruptcy re-dated 2002-12-01→2002-12-09; Fee Unbundling re-dated 2008-06-01→2008-06-12; COVID era re-dated 2020-03-01→2020-04-15 (CARES aid); current era re-dated 2026-06-29→2024-10-15 ($1.5B buyback resumption) and relabeled 'Buybacks & Loyalty Squeeze'; Continental Mega-Merger and Basic Economy & Buybacks kept.

Offsetting monetization (Basic Polaris business-class seat fees, bag-fee hike, MileagePlus earning cuts) and a May 2026 Newark accident reviewed but did not shift D1/D7 band placement. Overall 62→61, remains Severely Enshittified.
