Mileage reinstatement from qualifying activities:

Missing mileage for partners must be requested through the United Airlines partner directly (visit www.united.com/retrocredit and select the "Non-airline partners" section). All requests need to be made within 12 months of the date of the qualifying activity. This could be flights or hotel stay or rental car credit that has not yet been posted. If the date was prior to expiration that should reinstate the expired miles.

Other mechanisms of mileage reinstatement:

United Airline's mileage expiration policy requires that accounts have qualifying activity at least once every 18 months to keep miles from expiring.

Here are some options to have miles reinstated (max look back is 18 months):
