If you’ve flown on an eligible Frontier Airlines flight within the last 180 days but didn’t add your FRONTIER Miles account number at booking, don’t worry—you can still earn miles for those flights!

How to Request Miles for Past Flights 

1. Check your account first. Log in to your FRONTIER Miles account to see if your miles for recent flights have posted. Please allow up to 3 business days from your flight date for miles to appear.

2. Add missing flights. If miles aren’t posted after 3 days, enter your flight confirmation code in the “Add Trips” box on your profile page. Enter your 6-digit confirmation code.  

3. Match your ticket name with your account. To receive credit, the ticket name must exactly match the name on your FRONTIER Miles account. 

4. Processing time. Once added, miles will post to your account within 24-48 business hours. 

Important Information: 

The following tickets do not qualify for earning miles: 

  • Award or free tickets of any kind 
  • Tickets under trade/barter agreements with Frontier 
  • Refunded, forfeited, or unused tickets 
  • Charter flights 
  • Pass travel (airline employees and industry passes) 
  • Agency and staff discount tickets 
  • Tickets for extra seats for baggage, pets, or extra space 

Tips to Earn Miles on Future Trips
