91²Ö¿â's Preferred and Contracted Airline, United, is permanently getting rid of change fees for most Economy and premium cabin tickets for flights within the U.S., or between the U.S. and Mexico or the Caribbean. If you cancel your flight and don’t choose a new one right away, you’ll get a flight credit that you can use up to one year from your original ticket issue date.
Additional changes include free same-day standby ticket requests and seat upgrades for select passengers at no cost if available.
Basic Economy flights or international travel outside the Caribbean and Mexico that are issued by December 31, 2020, can be changes without fees.
