I'm running a bit behind schedule for my Frontier Airlines flight. How do I check-in quickly?

• You can check in online 24 hours to 60 minutes before your flight. Online Check-In lets you view your itinerary, buy bags/seats, and print your boarding pass. Online booking is best because airport bags cost more.

• Frontier's free iOS and Android app allows mobile check-in. The app makes checking in and getting your mobile boarding pass easy. You can skip the airport line and go straight to the gate with your mobile boarding pass if you're only carrying a carry-on.

• Airport Check-In: Airport Agent Assistance is available for ticket counter assistance.

If you've bought a bundle, carry-on bag, or FRONTIER Miles Elite level membership, look for the Priority Check-In lane at the ticket counters.

Remember, check-in and baggage must be completed 60 minutes before departure for domestic and international flights. Be ready to board 30 minutes before departure at the gate.
