- Act on this
A no-show can cancel the rest of the itinerary
Failing to check in or board within the required time can trigger a no-show cancellation, including cancellation of subsequent flights on the itinerary.
What to do: Treat the first flight's cutoff as protecting the whole trip.
- Act on this
Check-in closes 60 minutes before departure
Frontier check-in closes 60 minutes before departure on domestic and international flights, and opens 24 hours before. Frontier asks passengers to arrive at least 2 hours early.
What to do: Have bags and boarding passes handled before the 60-minute cutoff.
- Worth knowing
An airport agent costs up to $25 per passenger, each way
Airport Agent Assistance, for checking in or printing a boarding pass at the airport, costs up to $25 per passenger per direction. Checking in on the website or app and bringing your own boarding pass avoids it.
What to do: Check in on the mobile app and carry the mobile boarding pass.
