What is Froniter Airline's cancellation policy? Froniter Airline allows users to cancel bookings, but the cancellation policy depends on the type of booking. For flights, hotels, and vacation packages, some may offer free cancellation if you act within 24 hours. If your booking allows for free cancellation, you can cancel without incurring a fee. However, restrictions may apply based on the supplier. Always check your booking details carefully or call Froniter Airline support at +1-(866)-884-3314.
