Understanding your options, requirements, and deadlines can make the difference between a stress-free trip and a frustrating experience. In this guide, we will walk you through every detail of Frontier Airlines check in to ensure you’re fully prepared for your flight.
Frontier Airlines Check In Deadlines
Missing your check-in window can cost you your seat or lead to missed flights. Frontier enforces the following check-in deadlines:
Domestic flights: Check-in closes 60 minutes before departure
International flights: Check-in closes 60 minutes before departure
Baggage drop deadline: All bags must be checked at least 45 minutes prior to domestic flights and 60 minutes prior to international departures
It’s essential to arrive at the airport 2 hours before domestic flights and 3 hours before international flights to account for security, baggage, and any unexpected delays.

Personal Item (free): Must fit under the seat (e.g., backpack, purse)
Carry-On Bag (fee applies): Must fit in overhead bin
