If you forgot to add your MileagePlus account number to your reservation or at check-in, or you believe miles earned for your flight activity were not credited to your account, please remember that you must wait at least 72 hours (United or United Express) after your flight has been completed before requesting retro-credit. For partner retro-credit, allow 14 days from the date of qualifying flight activity, as it can take up to 14 days to appear on your mileage summary.

Request credit for my flight
In the event that mileage earned with United Airlines does not appear on your MileagePlus Summary, you may request a credit subject to the following conditions:

To submit your request, please select the online or mail retro-credit request

The following information will also be considered when validating flight activity on United flights:

• Flight Information should be for completed flights flown on United or United Express. For irregular operations, reroutes, and schedule changes use the flight information for the actual flight flown, not the flight that was ticketed.
• The more complete and accurate the information, the easier it will be to process.
• Please do not submit requests for retro credit on United flights until 72 hours after completion or 14 days for Star Alliance or Other Airline carriers of your trip.
• Flight activity that has already been credited to a frequent flier account (partner or United) is not eligible to be posted to a second account number or a different frequent flyer program.

Mileage credit for flights on Star Alliance or other airline partners

You can request retroactive credit by mail for your completed flight on a Star Alliance airline or another airline partner. Remember that your flight must have occurred less than 12 months ago in order for it to be eligible for credit.
