If you have an upcoming flight with this airline or looking to understand their travel guidelines more, you are in the right spot! Allegiant Air has relatively standard baggage restrictions that will be familiar to regular flyers.

When you fly with Allegiant you get to bring a carry-on and a personal item free of charge! As long as these items are within the airlines’ size limitations, you can bring these two items on without issue. If you need assistance devices or child-care items, those you can bring on without them counting towards your carry-on allowance.

Exceeding the sizing limitations for Allegiant means you will be charged a fee or denied if they are too large. To make sure you do not run into this problem, measure your luggage before going to the airport. 

Your checked bags should not exceed 62” linear inches (157.48 linear centimeters) in their dimensions. Otherwise, they will be considered oversized. These bags should also not exceed 40 pounds (22.68 kg), or they will be overweight. 

To quickly summarize Allegiant’s baggage restrictions, you are allowed a free personal item and the option to pay for a carry-on bag with each ticket. Your carry-on must not be larger than 22″ x 14″ x 9″. Otherwise, you will have to pay between $18 and $50 to check it under the plane. 

Checked bags must not be larger than 80 linear inches or 40 pounds, otherwise, you will face steep oversized fees. And if your checked bag is over 80 linear inches or 100 pounds, it will not be accepted at all. 

What Are The Size Limitations For Allegiant Air?

Sizing standards for Allegiant are very standard for the industry and can apply to pretty much every airline. You will see the phrase ‘linear inches/centimeters’ a lot when reviewing sizing limitations so different kinds of bags can be used for travel.

Linear inches or centimeters are found by adding up the length, width, and height of your bag. As long as the sum of these numbers doesn’t pass the linear limit, it is allowed!

Personal items are less regulated on airlines as the primary rule is they should be able to fit underneath the seat in front of you. If you are worried about your personal item being too big, measure it! 

A personal item on Allegiant should generally not exceed the measurements of 17″ x 13″ x 8″ or 38 linear inches. Typically a standard backpack, purse, briefcase, or laptop bag can fit in these dimensions without a problem.

Your carry-on should not exceed the measurements of 22″ x 14″ x 9″ or 45 linear inches altogether. There will be measurement bins around the airport to make sure your bag can fit, but it is best to measure beforehand to avoid any issues.

Carry-on size limitations are quite strict on Allegiant Air. An oversized carry-on can take space away from other passengers and cause problems for the flight. 

What Are The Weight Limitations For Allegiant Air?

There is no official carry-on weight limit for Allegiant Air! However, the general rule of thumb is to keep the weight under 40 pounds. This is because you will need to live your carry-on over your body to place in the overhead bins.

It is best to keep the packing light so there is no struggle during boarding. You will not run into any scales before going onto your flight. But if you pack the typical clothes and toiletries you are unlikely to get near this weight.

What Is Not Allowed In a Carry-On For Allegiant Air?

Allegiant Air follows the TSA restrictions for carry-on liquids, gels, and aerosols. These substances are only allowed in containers with a maximum size of 3.4 ounces (100 milliliters). All containers also must fit into a single, sealable clear quart-size plastic bag. Anything over these restrictions is not allowed in their carry-on.

Drugs such as tobacco, alcohol, marijuana, or e-cigarettes are not allowed in your carry-on. Other more obvious items such as firearms and explosives will not make it through TSA and onto an Allegiant Air flight.

Some lesser-known items you can not bring are pepper spray, hoverboards, lithium batteries, bleach, or any form of lighters. Since these items are not allowed in your carry-on, they are also not allowed in your personal item.

It is always best to make sure your liquids are in TSA-approved bottle sizes and there are no hazards in your luggage. Items such as a corkscrew or a screwdriver can be flagged, so be thorough!

If you happen to pack one of these banned items, you will likely get flagged at TSA and they will confiscate the items. Allegiant Air baggage restrictions align with those of TSA.

So even though the airline itself does not take these items from you, TSA will do so on their behalf. Accidents do happen, so if you forget one of the minorly banned items in your bag you will likely not be punished.

How Strict Is Allegiant Air About Carry-Ons?

Much like other budget airlines, Allegiant is relatively strict about its carry-on rules. When it comes to items allowed in carry-ons, those restrictions come from TSA and not the airline.

Those rules are for safety and can not be exempted. However, in terms of size and carry-on allowance, Allegiant has full control over this division. And the purpose of keeping these rules strict is because it keeps the tickets cheap!

If you are caught with an oversized carry-on or more than one, you will have to pay roughly double that you would normally. Following the sizing restrictions and carry-on allowance will make sure that you are not forced to pay more money, and that your flight is smooth and stress-free! The restrictions can be frustrating when discovered too late so it’s best to be prepared!

How Many Carry-Ons Can I Bring On Allegiant Air?

Regardless of your ticket, you will only be allowed to bring on a single carry-on item with you onto the Allegiant Air plane. Too many carry-ons stuffed into the overhead bins on the plane could cause them to suddenly open during the flight and fall onto the heads of other passengers. So never plan to bring more than one carry-on item per passenger.

Beyond the carry-on item and personal item, you will not be allowed to bring anything else onto the plane. If you have special items like strollers or wheelchairs, those may need to be checked. There are some items you are allowed to bring on that will not count towards your carry-on allowance.

Regardless of its special status, you can often check these items at the gate rather than at the ticket counter so you can use them at the airport. Be sure to communicate at the ticket counter or review the Allegiant website to understand these special cases better.

You are always allowed to bring a personal item on the plane. This includes items such as backpacks, purses, pillows, laptop bags, jackets, and other small items. The personal item must be small enough to fit underneath the seat in front of you. Meaning it can not be another small suitcase.

To summarize, you are only allowed a single carry-on and a personal item on Allegiant Air unless you have a special item that qualified otherwise.

Can I Bring a Purse and a Backpack On To Allegiant Air?

Generally speaking, you can absolutely bring a purse or backpack onto an Allegiant flight! These items tend to usually qualify as your personal item. Which makes it easy to keep at your feet during the flight. So long as the bag is not too large that it will not fit under the seat or bigger than 38 linear inches, you can certainly bring these bags along with you.

A traditional school backpack or simple purse fits perfectly in this space. You will run into problems if your backpack or purse is too large to fit under the seat in front of you. If you are looking to bring an extremely large backpack, such as one made for long hiking trips, that should be checked.

If you are looking to bring a traditional purse or backpack with you onto an Allegiant Air flight, you will have no need to worry. Even larger than average backpacks and purses as be brought as personal items. But if it gets too large you could use the bag as your carry-on item or check it under the plane.

Does Allegiant Air Charge For a Carry-On?

Allegiant Air is a budget airline and therefore does charge for carry-ons. The prices for carry-on range from $10 to $50 depending on the length and route of your flight. There is no set carry-on price, but the length of your trip should give you a hint about its range. Carry-ons with Allegiant must not be oversized and stay below 45 linear inches.

However, if you are caught with an oversized carry-on it will be checked at the same price as a larger bag. If you find yourself needing to check your Allegiant carry-on last minute, the bag will be around $50 when checked at the ticket counter. This is why it is best to carefully measure your bag to avoid the extra fees!

What Are Allegiant Air Checked Baggage Policies?

For checked bags, you want to make sure the luggage does not exceed 80 linear inches (157.48 linear centimeters). You will likely face steep oversized fees if your bag is larger than this.

It is best to be safe and measure your luggage before you leave. These limitations are very strict with Allegiant Air. It is better to be safe than sorry and take the time to measure your luggage!

With checked bags, you can not exceed 40 pounds (22.68 kg) in weight to only pay the basic fare. Even if your luggage is 41 pounds, you will have to pay an extra fee of $50 to check the bag. If your bag is over 100 pounds, it will not be checked onto the plane at all. So if you are worried about the weight, simply measure the bag with a scale at home.

If your checked bag is too big in dimensions you will have to pay a $50 – $75 fee. The oversized dimensions are those over the linear measure meets of 80 inches or 203 centimeters.

Overweight bags are those between 41 and 99 pounds. If the bag weighs more than 100 pounds it will not be excepted onto the plane. Additionally, if your bag is overweight and oversized, you will need to pay both the overweight fee and the oversized fee
