Allegiant Airlines Cancellation Policy: Fees, Refunds, Credits & Trip Flex

Canceling a flight on Allegiant Air results in one of three outcomes: a full refund to your original payment method, a non-refundable Allegiant travel credit voucher, or complete forfeiture of your itinerary balance. Under official Allegiant terms, cash refunds are restricted to cancellations completed within the federal 24-hour booking window or instances where Allegiant cancels or significantly alters your flight. All other voluntary passenger cancellations result in credit vouchers (minus applicable fees) or forfeiture if submitted too close to departure without Trip Flex protection.

Allegiant Airlines Cancellation Policy at a Glance

Critical 24-Hour Cancellation Rule

Allegiant complies with the U.S. Department of Transportation’s 24-hour reservation rule. Under Allegiant's Terms & Conditions, an entire air transportation itinerary may be canceled for a full refund back to the original form of payment only when all three of the following conditions are met:

1. Transaction Timing: The cancellation request is submitted within 24 hours of purchase.
2. Advance Purchase Window: The flight's scheduled departure was at least 168 hours (7 days) away from the exact time of booking.
3. Air-Only Requirement: The itinerary consists solely of air transportation and was not booked as part of a package containing ground elements (such as hotel rooms or rental cars).

If your reservation meets all three criteria, you will receive a full refund with zero cancellation fees. If you book a flight departing in four days and cancel it three hours later, it does not qualify for a cash refund because the purchase occurred within the 168-hour window.

Allegiant Cancellation Without Trip Flex & The $25 Fee

Allegiant Cancellation Without Trip Flex

When you cancel an air-only reservation without Trip Flex, your options are determined entirely by how far in advance you cancel:

• At least 7 days (168 hours) before departure: You are eligible to receive an Allegiant travel credit voucher. The airline deducts applicable cancellation fees along with electronic carrier charges and related booking fees. Cash refunds are not provided.
• Within 7 days (fewer than 168 hours) of departure: Standard carrier terms state that passenger-initiated cancellations receive no travel credit, voucher, or cash refund. All funds associated with the unflown flight segments are forfeited.
• Fare Differences: If an itinerary is altered rather than canceled, you are responsible for any increase in fare; fare decreases are not returned in cash.

The $25 Cancellation Fee Explained

For qualifying voluntary cancellations completed at least 7 days before departure without Trip Flex, Allegiant assesses a cancellation fee of $25 per passenger, per segment.

A segment is defined as one takeoff and one landing:

• A non-stop, one-way flight is one segment ($25 fee per passenger).
• A standard round-trip ticket consists of two segments (outbound and return), resulting in a $50 fee per passenger.
• A round-trip booking for a family of four represents eight total passenger segments, amounting to $200 in total cancellation fees.

In addition to the $25 per-segment fee, Allegiant retains electronic carrier charges and booking fees. If the base airfare of a segment is less than the cumulative fees, the residual value drops to $0, and no travel credit is issued.

Refund vs. Travel Credit & Voucher Validity

Does Allegiant Give a Refund or Travel Credit After Cancellation?

Understanding the distinction between an original-payment refund and an Allegiant credit voucher prevents unexpected surprises:

• Original Payment Refund: Monies are credited back directly to the credit card, debit card, or payment provider used during booking. Cash refunds are granted only under the qualifying 24-hour rule, under Total Bundle enhanced TripFlex terms, or when Allegiant cancels or significantly alters a flight.
• Allegiant Credit Voucher: A digital credit issued under the passenger's name for future travel on Allegiant. Vouchers are strictly non-refundable and non-transferable. They cannot be redeemed for cash, sold, or assigned to other passengers.

How Long Is an Allegiant Cancellation Credit Valid?

An Allegiant travel credit voucher is valid for travel completed within 365 days from the original reservation date—not 365 days from the date you clicked cancel.

Under Allegiant's Contract of Carriage, voucher expiration dates cannot be extended under any circumstances. The new travel booked with the voucher must be completed before the expiration date arrives.

Allegiant Trip Flex Cancellation Rules & Cutoffs

What Is Allegiant Trip Flex?

Trip Flex is an optional flexibility product offered exclusively during initial reservation checkout on allegiantair.com. It cannot be added retroactively after a booking has been confirmed.

• Fee Elimination: It eliminates the standard $25 per-passenger, per-segment change and cancellation fees.
• Deadline Extension: It extends the cancellation window down to 1 hour before scheduled departure for airline tickets (72 hours for vacation packages).
• Credit Outcome: For standard Trip Flex itineraries, canceling produces a non-refundable Allegiant travel voucher valid for 365 days from the original booking date. It does not provide an automatic cash refund.
• Fare Differences Apply: While change fees are waived, any difference between the original fare and a new flight’s price must still be paid by the traveler.
• Non-Refundable Fee: The money paid to purchase Trip Flex itself is non-refundable upon cancellation.

Can I Use Trip Flex More Than Once?

No. Trip Flex is strictly a one-time-use feature.

Once you apply Trip Flex to make a voluntary date modification, routing adjustment, or itinerary cancellation, the Trip Flex protection is completely exhausted. Any subsequent adjustments or cancellations are processed under standard carrier terms, meaning standard cancellation fees apply and the 7-day cutoff rule takes effect. Trip Flex does not provide unlimited changes or ongoing cancellation protection.

Trip Flex Cancellation Cutoffs

Trip Flex Refund vs. Travel Credit (Total Bundle Distinction)

Purchasing standard Trip Flex does not mean you receive a cash refund if you decide to cancel:

• Standard Trip Flex: Canceling an itinerary covered by standard Trip Flex converts the qualifying balance into a non-refundable, non-transferable Allegiant travel credit voucher. Carrier charges, electronic booking fees, and the cost of the Trip Flex product are retained.
• Total Bundle with Enhanced TripFlex: Allegiant offers a premium booking tier designated as the Total Bundle, which includes enhanced TripFlex. Customers holding a qualifying Total Bundle reservation are permitted to cancel their booking and receive a full refund to their original form of payment rather than a travel voucher. Always verify whether your booking includes standard Trip Flex or the Total Bundle tier at checkout.

Can Trip Flex Itself Be Refunded?

Under official Allegiant terms, the Trip Flex product may be canceled for a refund within 24 hours of purchase by contacting Allegiant Customer Care, provided that no itinerary changes or cancellations have already been executed. Outside this 24-hour window, the fee paid for Trip Flex is completely non-refundable and will not be returned or converted into voucher credit if the flight is canceled.

Canceling Within 7 Days & No-Show Policy

Can You Cancel an Allegiant Flight Within 7 Days?

Your ability to cancel an Allegiant flight within 7 days of departure depends on whether you have Trip Flex:

• Without Trip Flex: You cannot receive a travel voucher or cash refund. Passenger-initiated cancellations made within 7 days (168 hours) of scheduled departure forfeit all airfare and associated ancillary charges (including baggage and seat selection fees).
• With Trip Flex: You may cancel flight-only bookings up to 1 hour before scheduled departure and receive an Allegiant travel credit voucher with no $25 segment fee deducted.
• Airline Disruptions: If Allegiant alters the schedule or cancels your flight within the 7-day window, you retain full refund rights regardless of whether you own Trip Flex.

What Happens If You Do Not Show Up for an Allegiant Flight?

If you do not board your aircraft and fail to cancel or modify your reservation prior to the published check-in and departure cutoff deadlines, Allegiant marks your itinerary as a no-show.

Under Allegiant's Contract of Carriage, a no-show is treated as a customer-initiated cancellation after the deadline:

• All funds paid for that flight segment—including base fare, seat selection fees, and baggage fees—are completely forfeited.
• The airline automatically cancels all remaining segments on the itinerary, including any return flights, with zero credit or refund provided.

Simply failing to arrive at the airport will never generate an automated voucher.

2. Enter the passenger's First Name, Last Name, and the 6-character alphanumeric Confirmation Code.
3. Open the Trip Summary screen.
4. Locate the cancellation tool and select Cancel My Entire Trip or the specific cancellation button displayed by the active interface.

6. Confirm the cancellation.
7. Save the cancellation confirmation number and the digital travel voucher code sent to your email.

Review our walkthrough on managing reservations in the Allegiant Manage Booking guide.

Can I Cancel One Passenger From an Allegiant Reservation?

Yes. If multiple travelers share a single booking confirmation code, you do not have to cancel the entire reservation.

In the Manage Travel portal, locate the specific traveler’s name and select the "Remove Traveler" option. This process can be repeated for other individuals on the reservation, provided at least one traveler remains on the original itinerary. Standard cancellation fees ($25 per segment) or Trip Flex rules apply specifically to the removed passenger's ticket. If only one passenger remains on the booking, the itinerary must be processed using the full trip cancellation workflow.

Can I Cancel Only One Flight of a Round Trip?

Yes, provided the cancellation is executed prior to the applicable cutoff deadline. In Manage Travel, select "Cancel only this Flight" for the specific flight segment you wish to drop.

If you cancel the outbound flight, ensure you verify that your return segment remains active and confirmed. If you miss or fail to cancel the outbound flight before departure, the airline will mark you as a no-show and automatically cancel your return flight.

Airline-Initiated Cancellations & Schedule Changes

What Happens If Allegiant Cancels Your Flight?

Airline-initiated cancellations operate under different rules than voluntary passenger cancellations. When Allegiant cancels a flight due to mechanical issues, weather, or crew scheduling limitations, federal consumer protections established by the U.S. Department of Transportation (DOT) take precedence:

• Full Cash Refund: If you choose not to accept the alternative travel offered by Allegiant, you are legally entitled to a 100% refund to your original payment method for the unflown portion of your ticket. This includes base airfare, government taxes, and all purchased optional services (such as seat selection and baggage fees).
• Free Rebooking: Alternatively, you may choose to be rebooked on the next available Allegiant flight to your destination at no extra cost. Because Allegiant operates point-to-point routes with low weekly frequencies, the next flight may not depart for several days.
• No Obligation to Accept Vouchers: You are not legally required to accept an airline voucher or credit if Allegiant cancels your flight. You have the right to insist on a prompt refund to your original payment card.

Monitor active flight operations using our live Allegiant flight status guide.

What If Allegiant Changes My Flight Schedule?

A schedule change occurs when the airline modifies flight times well in advance of departure:

• Minor Schedule Adjustments: If the schedule change is minor, Allegiant updates your itinerary and the ticket remains valid for the new times.
• Significant Schedule Disruption: Under U.S. Department of Transportation standards, if an airline makes a significant change to your departure or arrival time, or alters your origin/destination airports, and you decline the revised schedule, you are entitled to a full cash refund to your original form of payment.

Medical, Bereavement & Travel Insurance Comparisons

Does Allegiant Offer Medical Exceptions?

No. Allegiant’s official customer policy states that the airline does not grant exceptions to its cancellation or change rules for personal medical emergencies, illnesses, or hospitalizations.

If you must cancel due to illness and you do not have Trip Flex, standard cancellation rules apply: cancellations made 7 or more days before departure receive a credit voucher minus $25 per segment, while cancellations within 7 days forfeit all funds. If you purchased a comprehensive third-party travel insurance policy, you may file an independent reimbursement claim with your insurance provider.

Does Allegiant Offer Bereavement Exceptions?

No. Allegiant does not offer bereavement fares, nor does it provide policy exceptions or waivers for the death of a family member or travel companion. Standard cancellation fees, Trip Flex rules, and advance booking deadlines apply across all reservations regardless of bereavement circumstances.

Trip Flex vs. Travel Insurance

OTAs, Vacation Packages & Hotel-Only Bookings

What If I Booked Allegiant Through an Agency or OTA?

Allegiant sells almost all inventory directly via its official website and mobile app. If you booked through an online travel agency (OTA), corporate booking tool, or package vendor:

• Manage Travel Access: If you have an official 6-character confirmation code, you can generally retrieve your reservation to view flights, select seats, or purchase luggage.
• Processing Changes and Refunds: Cancellations, ticket adjustments, and cash refund requests must usually be processed through the third-party agency that issued the ticket.
• DOT 24-Hour Rule Applicability: The federal 24-hour refund mandate applies strictly to direct airline ticket purchases and does not bind third-party ticket agents to identical procedures. The agency’s independent cancellation policies and service fees will apply.

Allegiant Vacation Package Cancellation Rules

Vacation packages bundling flights with hotel accommodations or rental cars follow distinct rules:

• Excluded from 24-Hour Cash Refunds: Vacation packages containing land elements are excluded from the standard 24-hour cash refund policy.
• Trip Flex Package Cutoff: If your package includes Trip Flex, cancellations or modifications must be completed at least 72 hours before scheduled departure (compared to 1 hour for flight-only tickets).
• Third-Party Partner Terms: Hotels and rental car companies operate under separate supplier contracts. Even if Allegiant issues a credit voucher for the airfare portion, third-party hotel or rental car cancellation fees may apply depending on supplier policies.

Hotel-Only Bookings

If you purchased a standalone hotel reservation through Allegiant without airfare, flight cancellation rules do not apply. Standalone hotel bookings follow these terms:

• More than 7 days before check-in: May be canceled for a full refund back to the original payment method.
• Between 7 days and 24 hours before check-in: Eligible for a refund minus the cost of the first night’s room rate plus applicable taxes and fees.
• Within 24 hours of check-in: Non-refundable; cancellations inside 24 hours receive no refund or travel credit.

Fare Differences, Refund Timelines & Credit Calculations

Fare Differences on Rescheduled Flights

If you modify an Allegiant itinerary:

• Higher Fare: If the new flight segment costs more than the original ticket, you are required to pay the fare difference in addition to any applicable change fees.
• Lower Fare: If the new flight costs less, the residual fare difference is not refunded in cash. Depending on whether Trip Flex was applied, any eligible remaining balance is issued as an Allegiant travel credit voucher.

Refund Processing Timeline

Under Allegiant's Customer Service Plan and federal aviation rules, eligible refunds to the original payment method are processed according to these timelines:

• Credit Card Purchases: Allegiant transmits refund requests to card issuers within 7 business days of receiving a qualifying request. Depending on your banking institution, funds may take 1 to 2 billing cycles to post to your statement.
• Cash or Check Purchases: Processed within 20 business days.
• Travel Credit Vouchers: Digital vouchers generated through online cancellations are issued immediately to your email address and profile.

For unresolved billing issues, contact support using our Allegiant Customer Care directory.

How Cancellation Credits Are Calculated

Allegiant does not use a flat refund rate. The final credit or refund balance depends on your original fare, how close to departure you cancel, whether Trip Flex was purchased, and non-refundable service fees.

Before you confirm any cancellation online, Allegiant displays an itemized summary showing the exact amount to be returned.

Cancellation Scenarios & Decision Table

Practical Cancellation Examples

• Example 1: Air-only ticket canceled within 24 hours of booking (flight departs in 3 weeks). The booking meets all criteria: purchased directly, canceled within 24 hours, departs more than 168 hours away, and contains no land elements. Outcome: 100% cash refund to the original payment card with zero fees deducted.
• Example 2: Round-trip ticket for 2 travelers without Trip Flex canceled 14 days before departure. The booking has 4 passenger segments ($25 × 4 = $100 in cancellation fees). Outcome: The remaining balance after deducting $100 and carrier charges is issued as an Allegiant travel voucher valid for 365 days from the original booking date.
• Example 3: Flight-only ticket without Trip Flex canceled 4 days before departure. The cancellation is initiated inside the 7-day window. Outcome: Complete forfeiture of airfare and fees; $0 credit voucher issued.
• Example 4: Flight-only ticket with Trip Flex canceled 3 hours before departure. The cancellation occurs prior to the 1-hour cutoff. Outcome: The $25 segment fee is waived; remaining funds (excluding the non-refundable Trip Flex add-on fee) are issued as an Allegiant travel voucher valid for 365 days from booking.
