Frontier Airlines allows you to cancel your flight within 24 hours of booking for free, as long as the flight is more than seven days away. This 24-hour grace period applies to all ticket types and ensures flexibility for passengers who may need to change their plans shortly after booking.
After the 24-hour window, cancellation fees apply depending on how close to departure you cancel and the type of ticket you have. For example, standard fare tickets canceled within 60 days of departure incur a fee of $49 to $99. The remainder of your ticket price will be issued as a travel credit for future use.
