Avelo Airlines' cancellation policy states that passengers can cancel their reservation within 24 hours of booking and receive a full refund, as long as the booking was made at least 7 days prior to departure. If a passenger cancels their reservation after 24 hours, they may be subject to a cancellation fee. The fee amount varies based on the fare type and how close to the departure date the cancellation is made. Avelo Airlines also offers travel insurance, which may cover cancellations for certain reasons. Passengers can manage and cancel their bookings on the Avelo Airlines website or by calling customer service.
