UA Hub Airports
UA operates a "hub-and-spoke" type of route network, where most connecting flights feed through the hub airports. UA has five official hubs:
- Chicago O'Hare (ORD),
- Denver (DEN),
- Los Angeles (LAX), ,
- San Francisco (SFO), and
- Washington Dulles (IAD) international airports.
UA also has major presences at many other non-hub airports, such as Washington National (DCA). The articles here focus on UA-specific information related to each airport, including terminals/concourses used, locations and availability of elite security/check-in lanes, Red Carpet Club lounge locations and access, etc.
See Category:Airports for more general information about these and other airports.
