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.

Effective December 12, 2018, upgrade waitlists are processed in the following priority order:

1. Premier status of the traveler
2. Fare class¹
3. Chase United MileagePlus Club cardholders and Presidential Plus cardholders
4. United Corporate Preferred participant
5. Chase United MileagePlus cardholders with $25,000 annual spend²
6. Time of request

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.

This benefit does not apply to companions traveling on award tickets.
