MileagePlus® upgrades are a valuable feature of your membership that can make your flight experience that much more comfortable and luxurious. Here, you’ll find everything you need to know about upgrading your flight.
You can request a MileagePlus Upgrade Award while booking your flight or after booking your flight.
To request during booking:
Make sure you’re signed in to your MileagePlus account and have selected “Advanced search options.”
Enter your flight search criteria and choose “MileagePlus Upgrade Awards” for your upgrade type.
If none of the flights in your itinerary have upgrade availability, you can request the upgrade(s) later.
You’ll then be placed on a waitlist that will be cleared as upgrades become available. Learn more
You can request a PlusPoints upgrade at booking or after you've been ticketed.

To request an upgrade for an existing reservation, view the reservation on united.com or in the United app and select the Upgrade Reservation link, or call your designated Premier service line.
In addition to using PlusPoints for United flights, you can also request a PlusPoints upgrade on select partner airlines. Learn more

If you plan to travel with a lap infant, please call the airline you are traveling with first. Some Star Alliance partners do not allow lap infants to travel in a premium cabin, or you may need a special ticket.
