For most flights, you can check in on the Frontier app starting 24 hours before your flight's scheduled departure time. You must have your boarding pass and have any bags checked in by the below cutoff times before departure:

  • 60 minutes (domestic flights)
  • 60 minutes (international flights)

If you fail to check-in or to board your flight within the required time (check-in: 60 minutes prior to scheduled departure time; boarding: 20 minutes prior to scheduled departure time), your ticket will be deemed a No-Show Cancellation and cancelled. All subsequent flights, including return flights, on the itinerary, will also be treated as No-Show Cancellations. Please reference the Contract of Carriage for more details.
