How to change a United Airlines flight
Most major U.S. airlines, including United Airlines, have eliminated change fees on standard Main Cabin and premium fares for domestic and many international trips. You'll still pay any fare difference, and Basic Economy fares usually can't be changed. United removed change fees on most standard Economy and above fares for U.S. and many international itineraries; Basic Economy is non-changeable.
Fastest way to change: Call +1 (855) 302-0422 with your confirmation code.
Our agents will check your fare rules, find the best new flight, and rebook you in minutes — 24/7.
Cancelling a United Airlines flight & getting a refund
Under U.S. Department of Transportation rules, you can cancel within 24 hours of booking for a full refund if you booked at least 7 days before departure. If United Airlines cancels your flight or makes a major schedule change, you're entitled to a cash refund — not just a credit. Voluntary cancellations of non-refundable fares usually convert to a travel credit (eCredit) for future use.
For the full breakdown, see our guides on cancelling a flight and getting a refund and the 24-hour cancellation rule — or just call and we'll handle it.
United Airlines seat selection & upgrades
On United Airlines you can pre-select a seat (free or for a fee), pay for extra-legroom seating, or upgrade to first/business with miles, cash, or at check-in. Elite members often clear complimentary upgrades.
