  • Conclusion: Allegiant Carry-On Rules

Low-cost airlines, like Allegiant Air, may have lower base fares, but if you aren’t careful, you’ll end up paying more because of all their additional fees.   These include fees for checked and carry-on bags (as well as seat assignments, beverages, printing your boarding pass, etc..).

Spirit and Frontier are the worst offenders, but Allegiant can be challenging as well if you aren’t careful.

In this article, we’ll explain everything you need to know about Allegiant’s carry-on rules. This includes Allegiant’s carry-on and personal items size restrictions, liquid policy, and other rules and restrictions you should know before boarding your flight.

Allegiant Carry-On Policy

Allegiant allows one personal item onboard at no charge, but they charge for both carry-on and checked bags.  The personal item must fit under the seat in front of you, and the carry-on bag must fit and be stowed in the overhead bin or it will have to be checked.

Allegiant Carry-On Size

Allegiant Carry-On Bag Size

The maximum size for an Allegiant carry-on bag is 10 x 16 x 22 inches (25 x 40 x 55cm)

Baggage fees apply to carry-on and checked bags and vary depending on the route and when the bag is added to your itinerary. Additional charges for sporting equipment and/or overweight and/or oversize and excess baggage may apply.

The following are the fees you will pay for your carry-on and checked bag, each way, depending on your destination.

Time of PurchaseChecked BagCarry-On Bag
At Booking (Online)$35$30
Pre-Departure (Online)$45$45
At Airport (In Person)$50$50

If you want to know the exact cost for bags on your specific flight go to the Allegiant Baggage Fees Calculator and enter your travel route and date.

Does Allegiant Have a Weight Limit for Carry-on Bags?

Allegiant does not have a weight limit for carry-on bags. Checked bags cannot be over 50 lbs., but they do not specify a weight limit for carry-on bags and personal items.

Recommended Carry-On Bag

If you are looking for a great carry-on bag when flying Allegiant, I recommend the Travelpro Maxlite 5 Expandable Spinner. I have used this carry-on for years. It’s durable, reasonably priced, and holds everything I need for shorter trips.

As stated before, you will still have to pay a fee to carry this bag on an Allegiant flight, but it will cost a little less than a checked back and you won’t have to wait at the baggage carousel.

Travelpro Maxlite 5 21" Carry-On Expandable Spinner

This carry-on bag has been sizer bin tested to accommodate overhead bin space on most major US airlines.

Case Dimensions:

  • H: 21 in. W: 14 in. D: 9 in.

Note: If fully expanded it may not meet overhead bin size limits, so be careful to not overpack.

Allegiant Personal Item Size & Examples

Allegiant allows every passenger to bring one personal item onboard with them at no additional charge. Your personal items must be stored completely underneath the seat in front of you.

Examples of Allegiant personal items can include a purse, briefcase, laptop computer, iPad, camera case, or a similar-sized item.  Personal item dimensions must not exceed 8 in. x 14 in. x 18 in. (20cm x 35cm x 45cm).

Medical and assistive devices (including walkers, canes, and strollers), a diaper bag, a coat, a small umbrella, and food to be consumed on the plane do not count as personal items and can be brought on board at no additional fee.

Allegiant has bag sizers at the gate and they will double check to make sure your personal fits within their guidelines before you board your flight. If your personal item is too large, you will be charged a fee!

Allegiant Carry-On Liquids Policy

The rules for carry-on liquids are set by the TSA (Transportation Security Administration), not by the airline.  Allegiant will enforce the rules and policies of the TSA.

Each passenger may include in their carry-on bag One quart-sized bag of liquids, gels, and aerosols that are in travel-size containers no larger than 3.4 ounces (100 ml). Common travel items that must comply with the 3-1-1 liquids rule include toothpaste, shampoo, perfume, deodorant, and lotion.

Any liquid that does not meet the TSA 3-1-1 rule will either have to be checked with your luggage or will be thrown away at the security checkpoint.

Exceptions to this rule are certain medications and baby food/child nourishment.

Allegiant Food Policy

The TSA also sets the rules for what type of food you can bring on the plane.

When bringing food with you from home, an important thing to note is the classification of liquid vs. solid foods.   The general rule is “If you can spill it, spread it, spray it, pump it, or pour it, then it’s considered a liquid or gel,”.   This means your food may be considered a liquid.

Here’s a link to the TSA website advising what food can be brought with you on your Allegiant flight. 

Prohibited and Restricted Items

Certain items are considered dangerous and classified as hazardous materials.  Dangerous goods are prohibited from both your carry-on and checked bag on all Allegiant flights.  These rules are not specific to Allegiant and are mandated by the Federal Aviation Administration.

By Federal Law, certain items are considered hazardous and are prohibited from all Allegiant flights. Violation of Federal Law could result in up to 5 years imprisonment and a fine of $250,000 (49 U.S.C. 4124).

Restricted Items on Allegiant:

Items considered “dangerous goods” are prohibited under Allegiant’s carry-on policy and include the following:

  • Firearms and ammunition
  • Self-defense sprays, such as mace and pepper spray
  • Explosives, including fireworks and flares
  • Flammable liquids, including gasoline, lighter fluid, and kerosene
  • Poisonous, infectious, or radioactive substances
  • Knives and sharp objects (pocket knives, cutting instruments, razors, ice picks, carpet knives, metal scissors, box cutters, or similar items) 
  • Hoverboards, including electric skateboards, balance boards, gravity boards, and self-balancing devices
  • Medical or liquid oxygen 
  • Torch lighters, lighter fluid, strike-anywhere matches, and fire starters
  • Wet-cell batteries
  • For additional items check out Allegiant’s Restricted Articles List

It is important to note that this is not an exhaustive list and that the TSA’s rules and regulations are subject to change. When in doubt, leave it out.

Additional prohibited or restricted goods and materials can be found in the following resources:

  • IATA Dangerous Goods Regulations
  • TSA Permitted and Prohibited Items
  • FAA Packsafe List

Conclusion: Allegiant Carry-On Rules

In conclusion, Allegiant has a very straightforward carry-on policy that’s easy to understand and follow. You can bring one personal item (for free) and one carry-on bag (for a fee), with additional fees for larger bags or additional items.

It’s important to check the specific dimensions and weight restrictions before heading to the airport to avoid any unexpected charges or issues at the airport.
