Your Frontier confirmation code is a 6-character combination of letters and numbers — for example: FLY123.
Where to Find It:
If you booked on flyfrontier.com or in the Frontier app and provided an email address, you should have received a confirmation email shortly after booking.
→ Your confirmation code will be included in that email.
→ Be sure to check your inbox, junk, or spam folders in case it was filtered.
If you booked through a third-party travel site, you may receive more than one confirmation code:
• One from the travel agency
• One from Frontier
→ Use the 6-character Frontier confirmation code (e.g., FLY123) when managing your trip or checking in.
→ This ensures you receive the latest updates and flight information.
If you have a Frontier Miles account, log in to view your upcoming trips:
• On desktop: Go to your Perfil page and check the Upcoming Trip section
• In the Frontier app: Tap the Mis viajes tab
Your confirmation code also appears on your boarding pass.
