If a trip was completed within the last 180 days and you would like to earn mileage credit, log into your myFRONTIER account on FlyFrontier.com and access your profile. Under My Loyalty, select Retro Accrual, enter the confirmation code from the flown flight and then select Accrue.
Please keep in mind, only mileage from flights within the last 180 days is eligible for retroactive accrual.
