Waitlist priority on all flights
If upgrade space is not available when requesting a MileagePlus Upgrade Award, Regional Premier Upgrade or Global Premier Upgrade, travelers may be placed on a waitlist. Travelers placed on a waitlist are prioritized according to the Premier status of the traveler. If the request includes multiple travelers, then priority is based on the highest Premier status on the reservation. Waitlists are processed based on Premier status of the traveler, then fare class, then time of request.¹ New waitlist requests for MileagePlus Upgrade Awards, Regional Premier Upgrades, and Global Premier Upgrades can be made until 24 hours prior to departure.

Priority within four days on flights eligible for Complimentary Premier Upgrades
On certain flights, automatic processing of upgrades, including Complimentary Premier Upgrades, may begin as early as 96 hours (four days) in advance. The confirmation windows for Complimentary Premier Upgrades, by published Premier status, are:

The following is the order of priority for upgrades, within four days of departure, on flights that are eligible for Complimentary Premier Upgrades:

• Premier 1K members on eligible Y-, B- and M-class fares: Premier 1K Instant upgrades that weren't confirmed in advance are prioritized by fare class
• All travelers on waitlisted Global Premier Upgrades, Regional Premier Upgrades and MileagePlus Upgrade Awards: Prioritized by Premier status of the traveler, then fare class and then time of request¹
• All remaining Premier members: Prioritized by Premier status of the traveler, then fare class and then award travel²

Priority within 24 hours
New waitlist requests for MileagePlus Upgrade Awards, Regional Premier Upgrades and Global Premier Upgrades can be made until 24 hours prior to departure. If we haven't confirmed your upgrade by the time you check in for your flight, you will be added to the Upgrades list at check-in, so there's nothing that you need to do after submitting your original request. Our upgrade systems process requests, per the priority listed above, until three hours before flight departure, at which point our gate agents will handle all remaining upgrade requests. Learn more about the upgrade standby list.

A MileagePlus member may request an upgrade for another traveler using a MileagePlus Upgrade Award, a Global Premier Upgrade or a Regional Premier Upgrade, even if they are not traveling on the same reservation.

Waitlist confirmation priority is based on the Premier status of the traveler. If the request includes multiple travelers, then priority is based on the highest Premier status on the reservation.

In addition, one companion traveling on the same reservation as a Premier member is eligible for Complimentary Premier Upgrades on select flights, and may be confirmed with the same priority as the Premier member, even on the day of departure. This benefit does not apply to companions traveling on award tickets.
