How to File a Complaint with Allegiant Air

Allegiant Air complaints should start with the issue-specific path that matches the trip problem. Use Allegiant's contact page and Customer Request for Assistance form for written complaints, Manage Travel for eligible cancellations or changes, the airport Baggage Service Office or mishandled baggage report for bag issues, and the U.S. Department of Transportation for covered aviation consumer issues that remain unresolved.

Allegiant is an ultra-low-cost airline, so many fares, seats, bags, bundles, carrier charges, and booking fees have strict refund rules. A strong complaint should identify the exact rule or event that makes your request eligible, not just that the trip was frustrating.

Best Allegiant Air Complaint Paths

If you booked an Allegiant vacation package, hotel, car, or third-party activity, separate the air-ticket issue from the ground product issue. Package cancellation and change rules can differ from air-only rules.

Step-by-Step: How to File an Allegiant Complaint

What to Have Ready Before Filing

Do not send passport images, full card numbers, medical records, or identity documents through unofficial complaint sites. Use Allegiant's official forms, app, airport baggage office, or DOT's official complaint portal.

Refunds, 24-Hour Cancellation, and Trip Flex

Allegiant's Customer Service Plan says most travel purchases, hotel, auto, baggage and seat fees, booking fees, carrier charges, Trip Flex if applicable, and taxes are nonrefundable unless an exception applies. It also says customers can cancel an entire air transportation itinerary without penalty if the cancellation is within 24 hours after booking, the scheduled departure was at least one week away at booking, and the air transportation was not part of an air-and-ground package.

Trip Flex can change the outcome. Allegiant says Trip Flex allows customers to make qualifying changes or cancellations without the fees that would otherwise apply if the change or cancellation is made at least one hour before scheduled departure, or at least 72 hours before departure for vacation packages. Allegiant's Trip Flex page also says Trip Flex can be cancelled for a full refund up to 24 hours after the original purchase if no modifications have been made to the itinerary.

When filing a refund complaint, include:

• confirmation number
• whether the booking was air-only or a package
• whether Trip Flex was purchased
• cancellation or change timing
• payment record and fees charged
• whether Allegiant cancelled or significantly changed the flight
• requested outcome: cash refund, voucher correction, fee refund, or written explanation

For flights to, from, or within the United States, DOT refund rules may apply when an airline cancels or significantly changes a flight and the passenger does not accept the offered alternative.

Baggage Complaints

Allegiant's baggage FAQ says passengers should visit the airport Allegiant Baggage Service Office to complete a Mishandled Baggage Report. If the issue was not reported at the airport, Allegiant says the mishandled baggage report must be submitted within 12 hours of arrival time.

For baggage complaints, include:

• baggage tag number
• mishandled baggage report or file number
• flight number and arrival airport
• arrival time
• photos of damaged baggage before repair or disposal
• receipts for reasonable interim expenses
• payment record for checked-bag fees
• delivery address and phone number

Allegiant's baggage limitations page says it compensates passengers for reasonable, documented damages from loss, damage, or delayed baggage up to the applicable liability limit. DOT baggage guidance also says airlines must compensate passengers for reasonable, verifiable, actual incidental expenses while bags are delayed, subject to liability limits, and cannot impose arbitrary daily caps.

Accessibility and Special Assistance

Allegiant's FAQ directs disability and wheelchair assistance requests through the Special Assistance request during booking or through the Customer Request for Assistance form by selecting the Disability & Wheelchair assistance topic.

If the issue is urgent at the airport, contact Allegiant airport staff immediately. For a post-trip complaint, include the assistance requested, airport, flight number, timing, staff interaction, and any mobility device or service animal details relevant to the complaint.

When to Escalate Beyond Allegiant

DOT complaints are strongest when they include the Allegiant case, ticket or confirmation number, payment record, what Allegiant said, and the exact rule or remedy requested.

What to Say in an Allegiant Complaint

Use this script:

"I need Allegiant to review a complaint about confirmation number [number]. The flight was [flight number] from [origin] to [destination] on [date]. The issue is [refund, cancellation, Trip Flex, delay, baggage, accessibility, fee, package, payment, or service]. I have attached [itinerary, payment record, cancellation notice, Trip Flex receipt, baggage tag, mishandled baggage report, photos, receipts, or prior case number]. I am requesting [refund, voucher correction, fee refund, baggage reimbursement, accessibility review, or written explanation]. Please confirm the case number and next step in writing."

Useful follow-up questions:

• "Which Allegiant rule is being applied to this refund or voucher?"
• "Was this an air-only itinerary or a vacation package?"
• "Was Trip Flex used, unused, or cancelled within 24 hours?"
• "What document is missing from my case?"
• "Can you confirm the decision and reason in writing?"
• "If Allegiant denies the request, what appeal or DOT path applies?"
