Refund eligibility on Allegiant Airlines depends largely on the fare type and timing of your cancellation. While most Allegiant tickets are non-refundable after the 24-hour grace period, travelers may still cancel their bookings and receive credit for future travel. Refunds are typically only available during the 24-hour booking window, so it’s crucial to act fast if your plans change. Be sure to review your fare details to determine whether you qualify for a refund or travel credit.
