On standard domestic economy fares, United includes a carry-on and charges for checked bags. Basic Economy is more restrictive — no full-size carry-on on some fares — so compare fare types carefully.
United's hubs are Chicago O'Hare, Denver, Houston Intercontinental, Newark, San Francisco, Washington Dulles, and Los Angeles.
Book domestic flights 3–7 weeks ahead, fly midweek when you can, and watch for United's fare sales from Denver and Chicago — two of its most competitive hubs.
MileagePlus is United's free frequent-flyer program, with miles redeemable across the Star Alliance network of 25+ airlines worldwide.
United flies nonstop to more international destinations from the US than most competitors, with particular strength to Europe from Newark and Asia from San Francisco.
