How do I get FRONTIER Miles credit for a flight I've already taken?

If a trip was completed within the last 180 days and you would like to earn mileage credit, log into your myFRONTIER account on 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.

When all travel from your booking is complete, allow up to 72 hours for your earned miles to be reflected on your account.

Did you follow this process and not receive credit? Please fill out our Request Mileage Credit Form.
