Frontier Airlines will give you a refund for a cancelled flight, but it depends on the situation. If Frontier cancels your flight, you’re eligible for either a full refund or a travel credit that can be used toward future bookings. If you prefer, you can also be rebooked on a different flight at no extra cost.
If you cancel the flight, however, things are different. Refunds are typically not issued for non-refundable fares like Economy or Discount Den fares, unless you purchased the Refundability option at the time of booking. In this case, a travel credit valid for 90 days is usually provided. Frontier does allow you to cancel and************* within 24 hours of booking, provided the flight departs more than 7 days later.
