American Airlines Group: American Airlines is one of the world's largest airlines and, by fleet size, generally the largest. Its network runs through nine hubs, the biggest being Dallas Fort Worth with more than 930 departures on a peak day. Approximately 224 million passengers boarded its flights in 2025, carried by 1,013 mainline aircraft and 567 regional aircraft operating as American Eagle; 57 million of those passengers flew on regional flights, about 42 percent of them connecting to or from mainline services. As a network carrier it sells everything from Basic Economy to the lie-flat Flagship Suite on long-haul routes.

American Airlines Group business model: The business model of American Airlines is more complex than selling plane tickets. American runs a hub-and-spoke network through nine hubs, and the flying itself carries thin margins: in 2025 the company produced operating income of $1.5 billion on $54.6 billion of revenue, and net income of $111 million after $1.7 billion of net interest expense. A large share of the economics sits in the AAdvantage loyalty program, which sells miles to banks and other partners. Cash payments from co-branded credit card and other partners were $6.2 billion in 2025, and total loyalty revenue was $7.5 billion, split between $4.0 billion of mileage redemptions recognized in passenger revenue and $3.5 billion of marketing-services revenue. Citibank became the exclusive issuer of the AAdvantage co-branded credit card portfolio in the United States starting in 2026 under a 10-year agreement announced in December 2024, replacing a two-issuer arrangement with Citi and Barclays, and Mastercard remains the exclusive payment network for those cards under a 10-year contract signed in July 2025.

United Airlines Holdings, Inc. business model: United makes money by filling a hub-and-spoke network. Domestic and regional flights feed passengers into seven U.S. hubs, where they connect to long-haul routes across the Atlantic, Pacific and Latin America. Ticket sales are the core: passenger revenue was $53.4 billion of the $59.1 billion total in 2025. Pricing is segmented from Basic Economy through Economy Plus, Premium Plus and Polaris business class, and premium revenue has been growing faster than the main cabin. The second engine is MileagePlus: JPMorgan Chase buys miles for its co-branded United cards, which feeds the $3.9 billion of other operating revenue along with club memberships and ancillary fees. Cargo carried in passenger aircraft bellies added $1.8 billion in 2025.

The durability of a company's moat often decides long-term winners. Here is how the competitive advantages of American Airlines Group stack up against those of United Airlines Holdings, Inc..

American Airlines Group competitive advantage: American's advantages are hub density and loyalty scale. At Dallas Fort Worth it flies more than 930 departures on a peak day, moving more than 30 percent of its daily connecting customers and connecting bags through that one airport, and it is reorganizing the schedule into 13 banks from April 2026 to protect connections. Its eight other hubs are Charlotte, Chicago, Los Angeles, Miami, New York, Philadelphia, Phoenix and Washington, D.C., where gate positions and slots accumulated over decades are hard for lower-cost carriers to match on connecting business routes. AAdvantage adds switching costs at the top of the customer base: the program produced $7.5 billion of loyalty revenue in 2025, enrollments grew 7 percent, co-branded card spending grew 8 percent, and members earn miles with more than 1,000 non-flight partners.

United Airlines Holdings, Inc. competitive advantage: United's advantage is its hub network, international route breadth, Star Alliance connectivity, premium-cabin expansion, MileagePlus loyalty base, corporate account strength, and major positions at airports such as Chicago O'Hare, Newark, Denver, Houston, San Francisco, Washington Dulles, and Los Angeles.

Future prospects matter as much as current results. The growth strategies below explain how American Airlines Group and United Airlines Holdings, Inc. each plan to expand from here.

American Airlines Group growth strategy: American frames growth around four commercial pillars: a more consistent and elevated customer experience, more productive use of its network and fleet, partnerships that deepen loyalty, and better sales, distribution and revenue management. In practice that means more premium seats, with the Flagship Suite on Boeing 787-9s and Airbus A321XLRs and retrofits announced for the 777 and older narrow-bodies, long and thin international flying by the A321XLR including a first transatlantic A321XLR route from New York to Edinburgh announced for 2026, deeper oneworld and joint-business partnerships, and the exclusive Citi co-brand agreement that took effect in 2026. American launched more than 60 routes in 2025 and announced more than 20 more for 2026, and it is funding a larger Terminal F at Dallas Fort Worth to expand the hub.

United Airlines Holdings, Inc. growth strategy: United is investing in premium seating, larger aircraft, international routes, operational reliability, MileagePlus, airport clubs, digital service, Starlink connectivity, and network depth at core hubs.

Q2 fuel expense was up $2.3 billion (84%), and the company said it expected to recover all of the increase through fares by Q4. Management is targeting an investment-grade credit rating in 2026.
