Frequently asked questions

Can I earn Allegiant Air miles booking through Aviafares?

Yes. Our tickets are fully-eligible revenue tickets, you earn miles in the airline's own program (and any partner program with a valid fare class) exactly as if you booked on the airline's website. Enter your frequent-flyer number at checkout or add it after.

What if Allegiant Air cancels my flight?

We handle rebooking and refunds through our direct ticketing relationship with the airline. Call our 24/7 line as soon as you see a schedule-change alert, we often rebook before the airline's customer-service queue moves.

Do you book Allegiant Air upgrades?

We book paid upgrades at the time of ticketing. Post-booking upgrades (cash or mileage) must be done through the airline directly; we can talk you through eligibility rules on the call.

Allegiant Air changes or cancellations?

We ticket directly with Allegiant Air and handle irregular operations faster than most airline call centers. Call our 24/7 line with your PNR.
