United at a glance
United’s main US hubs include Chicago O’Hare, Denver, Houston (IAH), Los Angeles, Newark, San Francisco and Washington Dulles. Many routes connect through one of these hubs.
- Compare a nonstop flight with a one-stop fare. Connecting through a hub can be cheaper, but it adds travel time.
- Check the fare type before you buy. The lowest fares usually have stricter rules on seat selection, bags and changes.
- If you are flying abroad, check passport and entry rules for your destination before you book.
- Have your frequent flyer number ready when you call, if you have one.
