Refunds for preferred seating purchases are processed automatically after scheduled departure in the event of flight cancellation change, when travel is completed in a standard United Economy seat, or when travel is completed in a seat of equal or greater value through the purchase of a premium cabin seating offer.

What happens if I purchase Preferred Seating and then get upgraded?

In the event of an upgrade, with some exclusions, preferred seating purchases for the upgraded flight segment(s) will be automatically refunded. Exclusions include cases where a customer is reaccommodated into a seat of similar or greater value due to an aircraft change or other operational issue.
