If a flight is delayed by more than three hours due to circumstances beyond Frontier Airlines' control, like maintenance problems or scheduling faults, Frontier Flight Delay Compensation Policy the airline will usually reimburse the customer. Rebooking on the next flight, meal vouchers, and hotel accommodations for overnight delays are examples of eligible compensation. Under the guidelines of the U.S. Department of Transportation (DOT), passengers may be eligible for a complete refund or additional compensation if the delay results in a cancellation or denied boarding. However, delays brought on by inclement weather or restrictions on air traffic control typically do not qualify. EU Regulation 261 may potentially provide compensation for international flights leaving the EU.
