Allegiant Air Flight Changes

Can You Change Your Allegiant Air Flight?

Many Allegiant Air bookings can be modified, although the available options depend on your ticket type and fare conditions.

Eligible Bookings

Flight changes are generally available for eligible tickets booked directly with Allegiant Air. If your reservation was made through a travel agency or another booking provider, you’ll usually need to contact the original booking source to request changes.

Ticket Conditions

Your fare rules determine whether flight changes are permitted and whether change fees or fare differences apply. Passengers who purchase Trip Flex™ receive greater flexibility than standard fares.

Factors Affecting Flight Changes

Several factors may affect your ability to modify your booking, including:

• Fare type
• Seat availability
• Route
• Time remaining before departure
• Booking source

Types of Flight Changes Available

Change Travel Date

Eligible passengers may change their travel date before departure, subject to fare conditions, applicable fees, and fare differences.

Change Flight Time

You may request an earlier or later flight if seats are available and your fare permits changes.

Change Destination

Depending on your fare conditions, you may also be able to change your destination. Additional fare differences and applicable fees may apply. Trip Flex™ allows one itinerary change without change fees, although any fare difference still applies.

Update Passenger Information

Certain passenger details, such as contact information, can generally be updated through Manage Travel. Name corrections may require assistance from Allegiant Air customer support.

Things to Know Before Changing Your Flight

Before requesting a flight modification, consider the following:

Fare Differences

If your new flight costs more than your original booking, you’ll generally need to pay the fare difference. Without Trip Flex™, change fees may also apply.

Seat Availability

Flight changes depend on available seats in your selected fare class.

Time Before Departure

Without Trip Flex™, itinerary changes generally cannot be made within 7 days of departure. Passengers with Trip Flex™ can usually make one change up to 1 hour before departure.

Booking Source

If your reservation was made through a travel agency or third-party booking website, you’ll generally need to request changes through the original booking provider.
