About United Airlines
United Airlines (IATA code: UA) is one of the big three US network carriers and operates what is generally considered the most extensive route network of any airline in the world, measured by destinations served. It is headquartered in Chicago and traces its origins to 1926.
United operates hubs at Chicago O’Hare, Denver, Houston Intercontinental, Los Angeles, Newark, San Francisco, and Washington Dulles. San Francisco anchors its transpacific network, Newark and Dulles its transatlantic flying, and Houston its Latin America operation.
United is a founding member of Star Alliance, which connects it to Lufthansa, Air Canada, Singapore Airlines, ANA, Swiss, Turkish Airlines and dozens more. That makes it one of the strongest options for complex multi-continent itineraries — exactly the kind of routing our agents build by hand rather than leaving to a search engine.

Polaris is United’s long-haul business class, with lie-flat seats, direct aisle access on most aircraft, and lounge access at select hubs. Our agents frequently find Polaris fares below the published price through consolidator inventory.
