Planning to cancel your Allegiant flight? Understanding the Allegiant Refund Policy can help you avoid unexpected surprises. Most Allegiant tickets are non-refundable, but if you purchased Trip Flex, you can change or cancel your itinerary without paying change fees. If Allegiant cancels your flight or makes a significant schedule change, you may be eligible for a refund or travel credit, depending on the situation. Refund eligibility also varies based on the timing of your cancellation and the fare purchased. Before canceling, review your booking details carefully to understand your options and make the best decision for your travel plans.
