Learn About How to Change Flight on Allegiant Airlines

The Allegiant flight change policy has significantly changed in response to the COVID-19 pandemic around the world. The policy applies differently, depending on whether you’ve purchased the Trip Flex travel protection. 

Allegiant Flight Change Policy for Standard Tickets without Trip Flex 

  • Standard tickets booked on/before April 30, 2021 can be changed once without any penalty. If you’re not sure about when you’ll be travelling, you will receive an Allegiant airlines Credit Voucher for the full amount value your ticket for travelling later. 
  • Standard tickets booked on/after May 1, 2021 can be changed once for USD 25/passenger/segment. However, this temporarily reduced fee will be increased to USD 75 later.

Allegiant Flight Change Policy for Tickets with Trip Flex 

  • If you booked a flight ticket with the Trip Flex travel protection, you can change the flight, flight date, or destination only one time without being charged a Allegiant airlines change fee.  
    • You can also postpone your flight without being charged a change fee of USD 75 per way per passenger (currently reduced to USD 25) for: 
      • Up to 730 days (2 years) from the original booking date if you purchased your ticket after April 10, 2020. 
      • Up to 365 days (1 year) from the original booking date if you purchased your ticket before April 10, 2020. 

If you have plan to postpone your booked flight, you will receive a non-refundable and non-transferrable travel voucher which can be used for future travel per the expiration periods indicated above.  

  • You can make changes to your flight booking up to 1 hour prior departure, and up to 72 hours prior departure if you’ve purchased a hotel/air package. 


  • You can purchase the Trip Flex travel protection only at the time of booking your flight ticket, not later.
  • Adding the Trip Flex travel protection can cost between USD 8 – 20 per flight/per segment, depending on your route.

Allegiant Flight Change Policy for Award Tickets

If you’ve purchased an award ticket with the Trip Flex travel protection, you will not be charged any change fees for changing your flight (once) on Allegiant Air. 

If you haven’t purchased the Trip Flex protection with your award ticket, changing an Allegiant flight/trip will cost you USD 25 per passenger/per segment while the COVID-19 relaxations last, and likely USD 75 per passenger/per segment under normal circumstances.
