Q&A with Allegiant
How do I use my Allegiant promo code?
Choose an offer, copy the code, and follow the link to the Allegiant website where you can browse for your flights. Once you’ve found suitable flights or the right hotel package, enter the booking process. You will have the option of adding a car rental to your booking as well as extra bags or seats with more legroom. When you reach the Trip Flex option page, you will see a ‘Do you have an Allegiant voucher or promo code?’ tab. Click this, paste your code into the box provided, and hit ‘Apply’ to redeem your discount.
What is the Allegiant baggage allowance?
You can select your own baggage allowance during the booking process. So, whether you’re traveling light with a simple carry-on or need to check an additional suitcase into the hold, you can arrange the option that works best for you.
What are the Allegiant carry-on luggage dimensions?
All carry-on luggage and personal items must fit the Allegiant dimensions. Personal items must not exceed 7 in. x 15 in. x 16 in. (17.8cm x 38.1cm x 40.6) to ensure they will fit under the seat. Carry-on bags must not exceed 9 in. x 14 in. x 22 in. (22.9 cm x 35.6 cm x 55.9 cm).
Can I cancel my Allegiant trip?
Yes, most Allegiant itineraries can be canceled online. Please head to the Manage Travel section of your account to access your Trip Summary and select the Cancel My Entire Trip link. If you cancel within 24 hours of your initial purchase and more than a week in advance of your trip, you can expect a full refund. Otherwise, you may need to pay a cancellation fee, dependent on your exact booking.
Where can I find the information for Allegiant passengers with special needs?
Passengers with special needs should head to the FAQ section of the Allegiant website where information on topics such as flying with a battery-operated device, oxygen tank, or allergy can be found. If you need further information or require special assistance, please contact a member of the team before making your booking.
