6 min read

Understanding the Allegiant Airlines baggage policy before heading to the airport can help you avoid unexpected baggage charges, oversized-bag fees, and last-minute problems at the gate. Allegiant allows every passenger to bring one personal item free of charge, while carry-on and checked baggage generally require additional fees. The exact baggage price depends on your route and when you add the bag to your reservation.

Quick answer: Under the current Allegiant baggage policy, passengers can bring one free personal item up to 8 x 14 x 18 inches. A paid carry-on can measure up to 10 x 16 x 22 inches, while a standard checked bag can weigh up to 50 pounds and measure no more than 80 linear inches. Allegiant allows up to four checked bags to be reserved online, while its terms permit up to five checked bags per passenger.

Allegiant Airlines Baggage Allowance at a Glance

The simplest way to understand the policy is to separate your luggage into personal items, carry-on bags, and checked baggage.

Baggage Type	Maximum Size	Weight Limit	Fee
Personal Item	8 x 14 x 18 inches	Not specified	Free
Carry-On	10 x 16 x 22 inches	Not specified	Fee applies
Checked Bag	80 linear inches	50 lbs	Fee applies
Overweight Bag	Up to applicable limits	51–70 lbs / 71–99 lbs	Additional fee
Oversized Bag	Over 80 linear inches	—	Additional fee

Allegiant states that measurements include wheels, handles, pockets, and decorations, so travelers should measure their luggage carefully rather than relying only on the manufacturer's listed dimensions.

Allegiant Airlines Personal Item Policy

Every passenger can bring one personal item free of charge as long as it meets Allegiant's size requirements.

The maximum personal-item dimensions are:

8 inches high x 14 inches wide x 18 inches deep.

The item must fit completely underneath the seat in front of you. Examples can include a purse, briefcase, laptop bag, small backpack, camera bag, or similar small item.

This is an important distinction because an oversized personal item can be treated differently and may result in a baggage charge.

Before leaving home, measure your bag with its wheels, handles, pockets, and other exterior features included. If you're unsure whether your backpack qualifies, you can contact +1-844-584-7422 before traveling.

Allegiant Airlines Carry-On Baggage Policy

Unlike the personal item, an Allegiant carry-on bag is not automatically free. Passengers may purchase one carry-on bag that fits in the overhead compartment.

The maximum carry-on dimensions are:

10 x 16 x 22 inches.

Allegiant's current published optional-services information lists carry-on fees that can vary by route and booking stage, with its current fee page showing a range of $10 to $75. Airport charges can be higher, so travelers should check the baggage price associated with their specific itinerary before arriving at the airport.

If you are uncertain whether your luggage qualifies as a carry-on, contacting +1-844-584-7422 before your trip can help you determine what to expect.

How Much Does Allegiant Charge for Baggage?

There isn't one universal Allegiant baggage price for every passenger. Baggage fees vary according to the route, baggage type, and when the bag is added to the reservation.

Allegiant specifically recommends purchasing baggage in advance because airport baggage fees can be higher. Its published information currently states that airport bag fees can reach $75 each way per passenger, per bag for a carry-on and the first five checked bags.

Because prices can change according to the itinerary, passengers should check their reservation or Allegiant's baggage-fee information rather than relying on a generic online price.

Allegiant Airlines Checked Baggage Policy

Passengers who need more luggage can purchase checked baggage.

A standard checked bag can weigh up to 50 pounds (22 kg) and must not exceed 80 linear inches, calculated by adding height + width + depth. Allegiant's current baggage information says passengers can pre-purchase up to four checked bags, while the airline's terms allow a maximum of five checked bags per passenger.

For example, if a suitcase measures 30 x 20 x 10 inches, its total linear measurement is 60 inches, which is below the 80-inch limit.

Remember that the 50-pound allowance is not simply a recommendation. Bags exceeding that weight can incur additional charges.

Allegiant Overweight Baggage Fees

If your checked bag weighs more than 50 pounds, Allegiant can apply an additional overweight baggage charge.

According to Allegiant's published fee information:

51–70 pounds: additional $50
71–99 pounds: additional $75
More than 99 pounds: generally not accepted, with certain exceptions for specialized items

These charges are applied in addition to the applicable baggage fee.

That means weighing your suitcase before leaving home can prevent an expensive surprise at the airport. For baggage-related questions, travelers can also contact +1-844-584-7422.

Allegiant Oversized Baggage Policy

A standard checked bag should remain within 80 linear inches.

When the combined height, width, and depth exceeds 80 inches, an oversized baggage charge can apply. Allegiant's current published fee information lists an additional $75 charge for an oversized checked bag exceeding the standard 80-linear-inch limit.

Sports equipment can have different size and weight provisions, so passengers traveling with golf clubs, bicycles, musical instruments, or other specialty equipment should check the applicable rules before packing.

Can You Save Money on Allegiant Baggage?

Yes. One of the easiest ways to control baggage costs is to add your bags before reaching the airport.

Allegiant states that passengers can reserve bags during booking and through Manage Travel or online check-in. Airport baggage fees are generally higher than advance purchase prices.

A practical strategy is to decide how many bags you actually need before completing your trip preparations. If your belongings can fit into the free personal-item allowance, you may avoid a carry-on fee altogether.

What Happens If Your Carry-On Is Too Large?

An oversized personal item may be treated as a carry-on or subject to an applicable airport baggage charge. Similarly, a carry-on that exceeds the permitted dimensions may need to be gate-checked or incur additional charges. Allegiant also notes that overhead space can be limited.

This is why measuring your luggage before traveling is much safer than assuming a suitcase will fit once you arrive at the gate.

Allegiant Baggage Policy for Strollers and Mobility Devices

Certain items receive different treatment from normal baggage. Allegiant states that baggage fees do not apply to qualifying car seats, strollers, mobility aids, and assistive devices.

Passengers traveling with medical or accessibility equipment should check the specific requirements before departure because special handling rules can apply.

Tips to Avoid Allegiant Baggage Fees

The best way to reduce baggage expenses is to plan before reaching the airport. First, measure your personal item carefully and make sure it fits underneath the seat. Second, weigh checked luggage at home and keep it at or below 50 pounds. Third, compare the cost of purchasing baggage in advance with the airport price. Finally, avoid packing unnecessary items that could force you to purchase another bag.

Allegiant's baggage rules are particularly important for travelers using low-fare tickets because baggage and other optional services may be priced separately from the base fare.
