What Happens If My Upgrade Request Is Denied On United?

If your United Airlines upgrade request is denied, call +1-833-770-4333 right away to review your options and see if seats open up later. The United support team at +1-833-770-4333 can check for available upgrades, waitlist possibilities, or compensation alternatives. Denials usually happen when premium cabins are sold out or your fare class isn’t eligible. You can stay on the waitlist for automatic upgrades or try again closer to departure. If seats become available, agents can instantly confirm your upgrade over the phone.
