United Airlines Holdings, Inc. operates United Airlines, a major U.S. full-service passenger carrier providing scheduled air transportation for passengers and cargo. The company offers a comprehensive route network that covers domestic markets across the United States as well as extensive international service to Europe, Asia, Latin America, and the Pacific. United operates a mixed fleet of narrow- and wide-body aircraft on point-to-point and hub-and-spoke routes, and supports corporate and leisure travel through offerings such as premium cabins, basic economy, and ancillary services including baggage, seat selection and in-flight amenities.
In addition to passenger operations, United provides cargo services through United Cargo, handling freight, mail and specialized shipments. The company also markets packaged travel solutions via United Vacations and supports travel management for corporate customers. Its MileagePlus loyalty program is a significant part of its product ecosystem, offering frequent-flier benefits, co-branded credit card partnerships and elite status recognition that drives customer retention and ancillary revenue.
United traces its origins to the formative years of commercial aviation and has evolved into one of the largest U.S. network carriers. It is a founding member of the Star Alliance global airline network, which expands connectivity for customers through codeshares and reciprocal frequent-flier benefits with partner carriers. United’s operational footprint is anchored by major hubs including Chicago O’Hare, Newark Liberty, Denver, San Francisco, Houston Intercontinental, Washington Dulles and Los Angeles, enabling broad domestic feed and international long-haul connectivity.
As of mid-2024, Scott Kirby serves as Chief Executive Officer, overseeing the airline’s network strategy, fleet renewal efforts and initiatives to improve operational reliability and customer experience. United faces the same cyclical and regulatory dynamics as other legacy carriers — including fuel and labor cost pressures, capacity management, and evolving customer preferences — and continues to invest in fleet modernization, technology and service offerings to maintain competitiveness in global air transportation.
