Hypothetical American / United

Overview

American / United would be materially different from a United / JetBlue scenario. It would combine two large global legacy carriers, two mature Flight Attendant workforces, two established Flight Attendant unions, two hub-and-spoke systems with meaningful overlap, and two large balance sheets. The combination would not be a bolt-on acquisition of a smaller carrier; it would be the consolidation of two of the central carriers in the U.S. domestic and international network-carrier structure.

The business case would be scale-driven. A simple FY2025 arithmetic combination produces approximately $113.7 billion of operating revenue, $6.18 billion of operating income, $3.46 billion of net income, roughly 629.7 billion ASMs, and approximately 3,070 aircraft when mainline and regional aircraft are counted using each carrier’s reported categories. These figures are simple additive figures before purchase accounting, transaction financing, divestitures, integration costs, labor harmonization, pension or postretirement treatment, fleet rationalization, and DOJ remedies. [S6] [S8]

The regulatory problem would be extraordinary. Reuters reported that antitrust experts saw a United / American deal as highly unlikely to win approval because the combination would control roughly 40% of U.S. domestic capacity based on 2025 schedules, and American’s CEO publicly rejected the concept as anti-competitive. The most likely threshold issue is not whether remedies could be imagined; it is whether DOJ would accept any remedy package as sufficient for a two-mega-legacy-carrier merger. [S10] [S11] [S12]

The labor issue would also be fundamentally different from a majority-absorption case. American Flight Attendants are represented by APFA, while United Flight Attendants are represented by CWA-AFA. The post-merger representation issue would likely proceed through the National Mediation Board after a single-transportation-system finding, and the representation contest would be separate from seniority integration and from the negotiation of a single Flight Attendant CBA.

Methodology and fact / assumption boundary

This report uses a source-first approach. Public filings, public union sources, NMB decisions, DOJ materials, and current business reporting are treated as established facts. The report does not assume an agreed merger, a surviving brand, a purchase price, a board-approved transaction, a DOJ settlement, a divestiture package, a single-union outcome, a seniority list, a base closure, a single operating certificate, or a joint CBA.

Terminology and headcount convention: This report uses CWA-AFA throughout the narrative for the Association of Flight Attendants-CWA. A different form is retained only when reproducing an exact source title or direct quotation. Company employment, contract-covered population, and union membership counts are reported separately when source definitions or dates differ; they are not treated as interchangeable denominators.

Business profile of a merged American / United carrier

A merged American / United would be a two-network-carrier combination with deep U.S. domestic scale, large transatlantic and Pacific networks, a major Latin America and Caribbean presence from American, and a major Pacific and transatlantic platform from United. American publicly describes service with American Eagle to more than 350 destinations in more than 60 countries and hubs in Charlotte, Chicago, Dallas/Fort Worth, Los Angeles, Miami, New York, Philadelphia, Phoenix, and Washington, D.C. United’s investor profile lists seven domestic hub cities: Chicago, Denver, Houston, Los Angeles, New York/Newark, San Francisco, and Washington, D.C. [S29] [S30]

Q1 2026 snapshot

Hub overlap and network overlap

The overlap problem is direct. Both carriers have large positions in Chicago and Los Angeles. Both have Washington-area hub operations, with American centered at DCA and United centered at IAD. Both have New York-area exposure, with American at JFK/LGA and United at EWR/Newark. American would add dominant southern and Latin America-oriented hubs in DFW, CLT, MIA, PHL, and PHX; United would add DEN, IAH, SFO, and its broader Pacific/transpacific architecture. [S29] [S30]

Competitive position against other carriers

A simple American / United combination would be far larger by revenue than any single U.S. passenger carrier using FY2025 public results. For comparison, Delta reported $63.4 billion of operating revenue, $5.8 billion of operating income, and $14.1 billion of debt and finance lease obligations at year end; Southwest reported $28.1 billion of operating revenue and $441 million of net income; Alaska Air Group, including Hawaiian, reported $100 million of GAAP net income and $293 million of adjusted net income for 2025. [S26] [S27] [S28]

Likely integration risks

• Antitrust execution risk: DOJ could block the transaction outright or demand remedies large enough to damage the deal logic.
• Debt and cash-flow risk: A combined carrier would carry tens of billions of dollars of debt, finance lease, operating lease, and postretirement-style obligations before transaction financing.
• Labor harmonization risk: Pay scales are similar at near-term top scale, but reserve, rest, sit pay, vacation, sick, no-furlough, seniority, base, and grievance provisions would require detailed harmonization.
• Technology and operations risk: Two large legacy airlines would require systems, crew scheduling, airport, loyalty, fleet, maintenance, and training integration at a scale larger than most prior airline combinations.
• Hub rationalization risk: Chicago, Los Angeles, New York-area, and Washington-area overlap could create pressure to reallocate flying, which would directly affect bases, staffing, commuting, and seniority bidding.

DOJ and approval feasibility

The most likely legal outcome is not a routine remedy settlement. A two-large-legacy merger would invite a block case, a major structural-remedy demand, or both. The American/US Airways precedent shows that DOJ can settle a legacy-carrier merger with slot and gate divestitures. But the more recent American/JetBlue Northeast Alliance and JetBlue/Spirit precedents show a more aggressive posture toward airline coordination and consolidation. [S13] [S14] [S15]

Relevant precedent

Possible remedies if DOJ entertained settlement

The following are hypothetical remedy categories, not predictions and not facts. A DOJ package could include divestitures of slots, gates, facilities, airport assets, and route authorities, but DOJ could also conclude that no remedy is adequate.

Approval theory: The parties could argue that the merger would create a stronger global U.S. carrier, improve connectivity, rationalize fleets and hubs, and preserve competition through divestitures to low-cost, mid-size, or new-entrant carriers.

Block theory: DOJ could argue that the transaction combines two of the most important network competitors in the country, controls roughly 40% of domestic capacity, reduces competition at overlapping hubs and city pairs, and cannot be fixed through limited asset sales. [S10] [S13] [S14] [S15]

For labor planning, the practical conclusion is that any American / United integration timeline would be highly uncertain. A long DOJ review or litigation process would likely delay single-carrier processes, seniority integration implementation, contract integration, and any base or schedule changes.

What a DOJ remedy package would have to solve

A useful remedy analysis starts with an important limitation: DOJ does not ordinarily ask which physical assets the merging airlines happen to own in common and then require a matching list of divestitures. It identifies the relevant markets in which competition would be lost—often origin-and-destination city pairs, airport or metropolitan-area access, connecting markets, and network competition—and then asks whether entry or a structural remedy could replace the lost rivalry. The current 2023 Merger Guidelines presume competitive harm when a merger materially increases concentration in a highly concentrated market, and they separately recognize that eliminating substantial head-to-head competition can itself establish a competitive problem. [S40]

American / United would be especially difficult because some overlap is ordinary route overlap while some is network-structure overlap. DOJ's abandoned United / US Airways analysis is instructive: the Division treated Dulles, Reagan National and BWI as competing Washington-area platforms, identified hub-to-hub and connecting-market overlap, corporate and government contracting, and transatlantic competition, and concluded that the combination created problems in numerous markets. That historical structure closely resembles the Washington question that an American / United merger would create. [S41]

Where the structural overlap is greatest

What a serious remedy package could contain

Bottom line: LAX, SFO and many spoke markets look conceptually remediable through targeted structural divestitures. ORD and Washington are qualitatively different. There, the merger would eliminate rival hub systems. If DOJ concluded that preserving competition requires recreating an independent hub-scale competitor, the amount of flying, gates, facilities and network connectivity that would have to leave the merged carrier could become so large that the remedy erodes the economic case for the transaction itself. That is why this scenario cannot be evaluated as simply “American / US Airways, but bigger.”

American financial stress and the Pan Am asset-sale comparator

American's financial position warrants separate treatment from the merger case, but it should not be overstated. As of October 22, 2026, American was financially constrained, not a failing firm. At September 30 it reported $36.366 billion of total debt under its non-GAAP definition, $11.8 billion of total available liquidity, and more than $26 billion of unencumbered assets and first-lien borrowing capacity. Third-quarter revenue reached a record $16.3 billion, up 19.3% year over year, but the company still reported a $269 million GAAP net loss as fuel expense increased $1.9 billion year over year. For the first nine months of 2026, American reported $46.982 billion of operating revenue, a $580 million GAAP net loss, and $1.242 billion of net interest expense. It now expects a full-year adjusted loss of $1.60 to $1.00 per diluted share, with fourth-quarter fuel projected around $4.70 per gallon. [S48] [S49]

The contrast with United is now even clearer. United's third quarter produced $17.875 billion of operating revenue and $1.030 billion of net income; through nine months it reported $2.533 billion of net income. United ended Q3 with $17.7 billion of available liquidity and $26.4 billion of total debt, finance-lease obligations and other financial liabilities. American therefore remains a viable standalone carrier, but the two companies enter this hypothetical from materially different earnings and balance-sheet positions. [S50] [S51]

Pan Am: useful comparator, but not a prediction

Pan Am is useful here as a capital-structure and strategic-asset comparator, not as a claim that American is on the same path. The chronology also begins earlier than the familiar 1986 Pacific transfer. Pan Am sold its profitable Inter-Continental Hotels subsidiary for $500 million in 1981 while its airline operation was losing heavily. In April 1985 it agreed to sell its Pacific division—including routes, 18 aircraft and related assets—to United for $750 million; United's operational takeover began on February 11, 1986. [S63] In 1990, Pan Am agreed to sell major Heathrow route authorities and related facilities and aircraft to United for another $400 million as liquidity pressure intensified. Pan Am filed Chapter 11 in January 1991 after chronic cash shortages, high fuel costs and years of losses; later in 1991 Delta acquired substantially all of Pan Am's transatlantic routes and the Pan Am Shuttle. [S53] [S54] [S55] [S56] [S57]

A modern American asset-sale branch

The Pan Am comparison does not imply that American must sell network assets. American today has a large domestic hub system, a major loyalty franchise, substantial liquidity and borrowing capacity, and access to modern financing markets—advantages Pan Am lacked in comparable form. A more realistic stress ladder begins with financing and non-core monetization before reaching route-franchise sales.

Analytical takeaway: American's current financial problem is better described as high leverage plus thin earnings resilience than imminent failure. The Pan Am history matters because it shows why the composition of any future asset sale is more important than the headline cash proceeds. Selling financing assets or non-core property can preserve the network; selling strategic hubs, routes or airport franchises can solve today's liquidity problem by reducing tomorrow's competitive franchise.

Representation issue overview

American Flight Attendants are represented by APFA. United Flight Attendants are represented by CWA-AFA. In a hypothetical merger, representation would not automatically decide seniority integration or CBA integration. It would determine which organization, if any, is certified to represent the combined Flight Attendant craft or class after the NMB process.

A central campaign issue would be legitimacy: neither group could credibly tell the other that it is simply being absorbed. The merged Flight Attendant group would be composed of two large bargaining units, with two established cultures and two mature sets of contract expectations.

Post-merger NMB single-system and representation scenario

DOJ approval would not itself create a single Flight Attendant bargaining unit, and neither closing nor an FAA single operating certificate automatically determines representation. Those are different legal processes. The National Mediation Board has exclusive responsibility under the Railway Labor Act for determining representation and, in a merger, whether the combined operation has become a single transportation system for the particular craft or class. Existing certifications remain in force until the NMB issues a new certification or dismissal. [S59]

What the NMB actually looks for

The NMB asks whether integration is substantial, not whether every operational detail is complete. Its current merger procedures examine public and operational indicia including combined schedules or routes, standardized uniforms and branding, integrated operations such as scheduling or dispatch, centralized labor and personnel functions, common management and corporate officers, interlocking boards, a combined workforce, and common or overlapping ownership. [S59]

The September 2026 Republic / Mesa Flight Attendant decision makes the point unusually clearly. The NMB found a single transportation system even though the FAA single operating certificate was still expected 18–24 months later. The carriers already had common ownership and governance, centralized labor functions, significant JCBA implementation, an integrated seniority list, common personnel direction and public integration. Total operational integration was not required. [S60]

Hypothetical American / United sequence after DOJ approval

Illustrative showing-of-interest math

The following numbers are deliberately hypothetical to show how the current NMB rule works; they are not a forecast of the official eligibility list. Assume the combined eligible Flight Attendant craft or class contains 59,500 employees: 31,500 on the legacy United side and 28,000 on the legacy American side. The 50% showing threshold would be 29,750.

• CWA-AFA illustration: if NMB-validated incumbent evidence covered all 31,500 eligible legacy United Flight Attendants, that evidence alone would equal about 52.9% of the combined craft or class and could satisfy the showing threshold.
• APFA illustration: incumbent evidence covering 28,000 eligible legacy American Flight Attendants would equal about 47.1%; APFA would need valid additional support covering at least 1,750 employees from elsewhere in the combined craft or class to reach 29,750.
• Critical caveat: company employment, union membership and NMB voter eligibility are not interchangeable. The NMB's official combined eligibility list—and the evidence it validates—would control the actual calculation.

Why a contested election is plausible in this hypothetical

The two closest historical examples point in different directions. In United / Continental, the United Flight Attendant group was represented by CWA-AFA while Continental/CMI Flight Attendants were represented by IAM; the NMB found a single system, authorized an election and ultimately certified CWA-AFA after 21,780 votes were cast. The tally was 11,942 for the incumbent United-side organization, 9,745 for IAM, 28 write-ins and 65 for no representation. [S18]

American / US Airways followed a different path because APFA and CWA-AFA had negotiated a representation protocol under which CWA-AFA did not contest APFA's post-merger certification request. The NMB therefore did not conduct a head-to-head APFA/CWA-AFA Flight Attendant election. An American / United combination need not follow that precedent. If both organizations remained candidates and each satisfied the 50% combined-system showing, the United / Continental model is the more useful procedural analogue for a contested vote. [S17]

Seniority integration

Seniority integration should be front and center in any American / United labor analysis. It controls bidding power, reserve exposure, vacation, base transfers, furlough and recall, premium-position access, and long-term career mobility. It is also separate from the NMB representation question: the union that represents the combined craft or class is not automatically free to staple, end-tail, or re-rank employees outside the required seniority-integration process.

Established seniority-source facts

What data would be required

Public sources do not provide the complete current American and United Flight Attendant seniority-date lists. Without those lists, this report does not estimate individual placement, seniority percentile changes, base-by-base bidding impact, reserve movement, or furlough-order impact. The required data would include: current active and inactive Flight Attendant seniority lists, seniority date definitions, training-start dates, graduation or line-assignment dates where relevant, furlough and recall records, leaves or accrual adjustments, base assignments, and any prior merger adjustments already embedded in each list.

Practical effect for both groups

• American Flight Attendants: A date-based list would protect earlier American seniority dates against later United dates, but American employees would not automatically rank ahead of United employees merely because APFA represented a large group at American.
• United Flight Attendants: A date-based list would protect earlier United seniority dates against later American dates, but United employees would not automatically rank ahead of American employees merely because United might be larger in some merger transaction structure.
• Both groups: Relative seniority within each pre-merger group would likely be a central protection. The practical campaign question would be how each union explains the seniority-date method, training-day adjustments, dispute process, and base protections.

Section-by-section CBA comparison

The comparison below uses the American/APFA 2024 CBA and the final United/CWA-AFA 2026–2031 CBA published by United/CWA-AFA on September 24, 2026. It is Flight Attendant-only. It does not compare pilot, mechanic, fleet-service, dispatch, agent, or management groups. Because implementation of both agreements has occurred in stages, the analysis distinguishes negotiated text from implementation status where that distinction matters. [S4] [S39]

Contract strengths and weaknesses at a glance

Neither agreement is uniformly stronger. American tends to be strongest where it converts operational failures or transaction risk into specific protections, while United is often stronger where it creates higher economic floors, more formal plan governance, or more explicit merger sequencing. The practical weaknesses are equally important: a provision can be economically rich but difficult to enforce, or legally strong but dependent on delayed implementation.

Work-rule and legalities comparison

Section-by-section comparison matrix

Best-of combined contract architecture

A combined Flight Attendant agreement should not simply average the two CBAs and should not assume the surviving airline’s existing CBA controls. The strongest model is sometimes a direct higher-of choice, but in many areas the two agreements protect different dimensions of the same problem. The matrix therefore distinguishes pick-the-stronger-rule items from areas where a genuinely better agreement would combine complementary architecture. It also treats enforceability and implementation as part of contractual value, not as afterthoughts.

Local representation and governance

CrewSignal governance references: APFA Union Governance · CWA-AFA Union Governance

APFA and CWA-AFA would present materially different representation architectures to a merged workforce. APFA’s current bargaining constituency is concentrated at American Airlines. CWA-AFA is a multi-carrier Flight Attendant union, but United is itself one of its largest constituencies and retains a substantial carrier-specific Local Council and MEC structure. The comparison is therefore not between a carrier-focused union and an organization with no United-specific governance; it is between single-carrier institutional concentration and carrier-specific governance nested inside a broader multi-carrier federation. [S23] [S31] [S33]

Headcount and denominator note: Public sources do not use one identical United denominator. CWA-AFA’s May 12, 2026 ratification release described the contract group as “nearly 30,000” United Flight Attendants, while United/CWA-AFA’s May 28 material referred to “over 30,000” United members. Current company workforce information supplied for this project places United Flight Attendant employment above 31,000. The report treats company employment, contract coverage, and union membership as distinct measurements rather than forcing them into one count. [S31] [S32]

Direct accountability: The most concrete governance difference is the chain through which members exercise authority. APFA members directly elect National Officers and Base Presidents. CWA-AFA members directly elect Local Council officers, and those Local Presidents exercise union-wide Board votes with the strength of the councils they represent. The 2026 CWA-AFA Board considered direct membership election of International and MEC Officers, but did not adopt either proposal. That difference is relevant to member accountability, but it does not itself establish stronger bargaining, enforcement, or service performance. [S23] [S33] [S34]

Resource concentration versus pooled infrastructure: APFA’s single-carrier model concentrates organizational attention on American, but its own 2026 financial reporting shows that concentration does not eliminate budget pressure. CWA-AFA combines broader institutional resources with airline-level MEC and Local Council structures, and its published budget policy allocates MEC funding through a carrier-specific formula. The analytically useful question is therefore how much bargaining authority, funding, local enforcement capacity, and member control the combined Flight Attendant group would actually exercise under either structure—not whether the label “single-carrier” or “multi-carrier” is inherently superior. [S35] [S36]

The governance issue is therefore not just a union election issue; it is an operational-risk issue. Flight Attendants would need enforceable local representation while bidding systems, hotels, reserve practices, safety reporting, discipline, scheduling, and base procedures remain separate or are phased into a common platform.
