MileagePlus Upgrade Awards

Use your miles to upgrade and fly in a premium cabin.

MileagePlus® Upgrade Awards let you use your miles to upgrade into United Global FirstSM, United First®, United BusinessFirst® or United Business® on most paid tickets. Upgrades from some discounted booking codes will require both miles and a co-pay.

Eligible flights

MileagePlus Upgrade Awards can be used on any United- or Copa-operated flight, with minimal fare restrictions.

Confirmation priority

MileagePlus Upgrade Awards may be confirmed as early as the time of upgrade request submission. On United-operated flights, if upgrade space is not available at the time of request, members can be placed on a waitlist.

Learn about co-pay

If you request a MileagePlus® Upgrade Award on certain United flights, you may have to supplement the miles for the upgrade with a co-pay.

Premier members will also not be charged a co-pay for flights within Intra-Asia (except between NRT and BKK/SIN) and non-stop flights to/from GUM (except between HNL and GUM).
