Cancel your Avelo Airlines flight with a Touriyo agent

• 'When you cancel or remove items from your reservation, you will receive Avelo Cash' (electronic credit, valid one year from the booking date for customer-initiated changes/cancellations per the contract of carriage), minus the change/cancel fee percentage above unless AveloFlex was bought.
• Contract of carriage: 'Nonrefundable Reservations.
• The fare paid for unused travel by Customers who purchase restricted, nonrefundable Reservations are not eligible for refunds, except as provided in Section 3(H)(i) and Section 12.'
• Refund to the original form of payment: cancellation within 24 hours of booking (booked at least one week before departure); Avelo cancels or significantly delays/changes the flight and the customer does not fly (14 CFR 260.6); 'When a refund is due, it will be provided within 7 business days of receiving a completed refund request for credit or debit card purchases, and within 20 days for other types of purchases.'
• Right after booking: Contract of carriage: 'Following receipt of payment from a Customer, Avelo will allow a Reservation to be held at the quoted fare for 24 hours if the Reservation is made at least one week prior to the flight's departure. If such Reservation is canceled within 24 hours of booking, Customer will receive a full refund without assessment of a cancellation fee.'

The commitment says fares bought by phone may be higher than online; all self-service is via Manage Trips.
