Frontier Airlines allows you to cancel your ticket up to 12 hours before the actual departure time of your flight. Frontier Airlines may charge a Frontier Airlines cancellation fee if the ticket is canceled 24 hours after booking. If your flight is canceled or delayed by more than 5 hours, you can file a complaint and ask for a refund. The airline will provide all the common facilities you need.
Frontier Airlines cancellation policy states that when passengers cancel their flight, whether on purpose or by accident, they must pay a cancellation fee to be eligible for a refund. If a passenger refunds a ticket after check-in, the airline will not refund it; all money will be confiscated as a no-show fee.
