American Airlines

American Airlines was assembled through the consolidation of 82 small US regional carriers in the late 1920s and early 1930s, with the holding company that became American Airlines incorporating in 1930. The carrier's first CEO of consequence was C.R. Smith — a businessman from Texas who transformed American from a mail carrier into the country's first truly commercial airline. Smith pioneered the DC-3 as a passenger aircraft (convincing Douglas to extend the DC-2 into the DC-3 specifically for American's sleeper service), created the first frequent flyer card (the AAdvantage programme in 1981), and introduced the Sabre computerised reservations system in the 1960s — which later became the most important airline booking system in the world.

The Airline Deregulation Act of 1978 ended government control of airline routes and fares. American Airlines responded more aggressively than any competitor: under CEO Robert Crandall, the airline pioneered the modern hub-and-spoke model, built Dallas/Fort Worth into a dominant connecting hub, and launched the AAdvantage frequent flyer programme — the first in airline history — in 1981. Crandall also used the Sabre reservation system as a competitive weapon, designing it to list American flights preferentially. The Department of Justice eventually forced changes to the system's display rules, but by then American had achieved enormous distribution advantages.

American Airlines filed for Chapter 11 bankruptcy in November 2011, the last major US carrier to do so. The bankruptcy allowed American to restructure its labor costs and pension obligations significantly. During the bankruptcy process, American merged with US Airways in 2013 — creating what was, at the time, the world's largest airline by passengers and available seat miles. The combined airline retained the American Airlines brand and AAdvantage programme, which had grown to over 115 million members and was valued at tens of billions of dollars independently.

American entered the COVID-19 pandemic carrying more debt than any other US airline, having borrowed heavily to fund aircraft orders and shareholder returns. Government CARES Act funding and additional borrowing allowed the airline to survive the pandemic, but emerged with a debt load exceeding $40 billion. The combination of high leverage, higher fuel costs, and a sales team that had missed the premium cabin pivot its competitors made earlier created a gap between American's revenue performance and Delta's and United's that the airline struggled to close.

American reported $54.6 billion in revenue for 2024. The airline operated the world's largest commercial aircraft fleet — approximately 900+ mainline jets — and carried more passengers domestically than any other US carrier. Its market capitalisation of approximately $10.5 billion was dramatically lower than Delta's ($36 billion) or United's ($22 billion), reflecting the market's concern about its debt load rather than its operational scale. A new commercial strategy launched in 2024 attempted to recapture corporate travel customers and restore the AAdvantage programme's competitive standing after strategy missteps earlier in the decade.
