United Airlines
United Airlines at a glance
United Airlines flies to more destinations than any airline in the world, 360+, from a seven-hub US system anchored at Chicago O'Hare, with the largest transpacific and overall international network of any US carrier. Its mainline fleet passed 1,000 aircraft in 2025 as the United Next order book, the largest in American aviation history, delivers a stream of 737 MAXs, A321neos and widebodies.
Under Scott Kirby, United has paired that scale with aggressive modernization: Starlink Wi-Fi fleetwide, the biggest 787 order ever placed by a US airline, and 50 A321XLRs to open thin long-haul markets. Its Star Alliance anchor role and joint ventures with Lufthansa, Air Canada and ANA complete the global web.
