Assistance for delays brought on by circumstances under the airline's control, like crew availability or mechanical problems, is provided by Frontier Flight Delay Compensation Policy' flight delay compensation policy. Passengers may be eligible for hotel rooms, travel credits, or meal vouchers for overnight delays, depending on how long the delay lasts. Although rebooking alternatives are usually available, compensation is not guaranteed for unpredictable occurrences like weather. In the event that delays surpass three hours for aircraft departing from the European Union, passengers may be eligible for compensation under EU Regulation 261/2004. In the event that passengers decide not to go, refunds are also possible for major delays.
