By adhering to the Frontier Flight Change Policy rules, travellers can simply change and reschedule their flights. Depending on availability, this policy gives passengers the option of standby travel or other flight alternatives. Only if the information on your ticket is accurate will you be able to modify your reservation, and you must do it at least one week before the scheduled departure. If the adjustments are made 60 days or more before the intended departure, they can be made without charge; however, if they are made later, a cost might apply. If you do it within 24 hours of booking, you can also do it for free.
