Allegiant Carry on Bag Size and Luggage Rules

Traveling with Allegiant Air requires a strategic approach to packing to ensure you avoid high fees at the boarding gate. Understanding the specific Allegiant carry on bag size requirements is the first step toward a stress free travel experience. This guide provides the exact measurements and rules you need to pack with confidence and arrive prepared.

Official Allegiant Carry on Bag Size Limits

Allegiant Air classifies baggage into two distinct categories: personal items and carry on bags. Unlike many traditional carriers, Allegiant only includes one small personal item for free with every ticket. Any luggage intended for the overhead bin requires an additional fee, which varies based on your route and when you purchase the allowance. To help you plan, the table below outlines the specific dimensions for each type of luggage.

It is important to note that these measurements must include any wheels, handles, or side pockets. If your bag exceeds the allegiant carry on bag size even by a fraction of an inch, you may be forced to check the bag at the gate for a significantly higher fee than if you had paid in advance. For more details on how these rules compare to other airlines, you can read our guide on United Airlines carry on luggage size rules.

How Strict is Allegiant with Carry on Size Measurements

Allegiant is widely known for being quite strict regarding luggage dimensions. Because their business model relies on low base fares and optional add ons, they carefully monitor bag sizes at the gate. Most Allegiant terminals feature a metal luggage sizer near the check in counter and the boarding gate. If an agent suspects your bag is too large, they will ask you to place it inside the sizer. If the bag does not slide in easily, it will be deemed oversized.

Soft sided bags like duffels often have an advantage because they can be compressed slightly to fit. However, if you pack a leather duffel bag to its maximum capacity, it may lose that flexibility. Many travelers prefer using specialized bags that are built specifically to meet airline standards.

What Size Bag Can You Carry on Allegiant for Free

The only bag you can bring on an Allegiant flight for free is a personal item. This item must be small enough to fit completely under the seat in front of you. The dimensions for this free bag are 7 inches deep, 15 inches wide, and 16 inches tall. Common examples of personal items include small backpacks, purses, laptop bags, or briefcases. If you are trying to decide which bag type is right for your next trip, check out our comparison on personal item vs carry on bag sizes.

For those looking to travel light and avoid fees, the Luhxe Hoodie Backpack is an excellent choice. It is designed for travelers who need a functional, stylish bag that fits comfortably within small spaces. When using a personal item, efficiency is key. You should prioritize packing essentials like electronics, medications, and one change of clothes if possible. If you need more room, it is always cheaper to pay for a carry on bag during the initial booking process rather than waiting until you get to the airport.

Can You Bring a Backpack and a Purse on Allegiant Flights

A common question among travelers is whether they can bring both a backpack and a purse for free. On Allegiant, the answer is no. Allegiant allows only one free personal item. If you bring both a backpack and a purse, the airline will count them as two separate items. This means you would be required to pay for the second item as a carry on bag or a checked bag.

The best way to handle this is to consolidate. You should place your purse inside your backpack or use a versatile bag like the Luhxe 3 in 1 Tote Bag. This allows you to have the functionality of multiple bags while appearing as a single unit during the boarding process. Once you are on the plane, you can take your purse out if needed, as long as everything fits within your designated storage space.

Choosing the Best Bag for Allegiant Flights

Selecting the right luggage can make the difference between a smooth boarding process and a stressful confrontation at the gate. For travelers who are willing to pay the carry on fee, the Luhxe Travel Bag 2.0 is a premier option. This flagship bag functions as a convertible garment and duffel bag, making it perfect for business professionals who need to keep suits or dresses wrinkle free. It also comes in a roller wheels variation, which fits perfectly within the 22 by 16 by 10 inch allegiant carry on bag size limit.

If you prefer a more classic aesthetic, a premium leather duffel bag offers durability and style. Leather bags are often more flexible than hard shell suitcases, allowing them to fit more easily into crowded overhead bins. Luhxe offers high quality travel bags ranging from $110 to $280, providing options for different budgets and style preferences. When shopping, always look for features like dedicated shoe compartments or exterior pockets for easy access to your passport and boarding pass.

How to Measure Your Bag for Allegiant at Home

To avoid any surprises, you should measure your bag at home before heading to the airport. Start by packing the bag exactly as you intend to for your trip. A bag that fits when empty might bulge and exceed dimensions when full. Use a standard measuring tape to check the height, width, and depth. Remember that Allegiant counts the wheels and handles in their measurements. Many people make the mistake of only measuring the body of the suitcase, which can lead to it being rejected by the gate agent.

Another helpful trick is to place your bag against a wall and mark the height and width on the floor and wall. This gives you a clear visual of the physical footprint of your luggage. If you find that your bag is slightly over the limit, try removing bulky items and wearing them on the plane instead. According to the official Allegiant baggage policy, items that do not fit in the sizer must be checked, so accurate home measurement is your best defense against extra costs.

Strategies to Avoid Allegiant Oversize Bag Fees

The most effective strategy to avoid fees is to pay for your bags at the time of booking. Allegiant uses a tiered pricing model where the cost of a carry on bag increases as you get closer to your departure date. Paying at the airport check in desk is more expensive, and paying at the gate is the most expensive option. If you are unsure whether you will need a carry on, it is usually safer to pay for one in advance than to risk a gate fee that could exceed $50 or $75.

Another tip is to understand the boarding process. Allegiant boards passengers in zones. Those who have paid for a carry on bag usually board in earlier zones, ensuring they have access to overhead bin space. If you are traveling with a personal item only, you will likely board later, but you do not need to worry about bin space since your bag must go under the seat.

Packing Essentials for Budget Airline Travel

When you are limited by the allegiant carry on bag size, you must be disciplined with your packing list. Use packing cubes to compress your clothing and keep your bag organized. This is especially helpful if you are using a duffel bag, as it prevents items from shifting and creating bulges that might make the bag appear oversized. Focus on versatile clothing pieces that can be mixed and matched to create multiple outfits from just a few items.

Always keep your liquids in a clear, TSA approved bag to speed up the security process. You can find more information on liquid requirements on the TSA official website. Additionally, consider the weight of your bag. While Allegiant does not have a strict weight limit for carry on luggage, you must be able to lift the bag into the overhead bin without assistance. If your bag is too heavy for you to handle, the crew may require you to check it for safety reasons.

Frequently Asked Questions About Allegiant Luggage

Many travelers find themselves confused by the specific terminology used by budget airlines. It is important to distinguish between a personal item, a carry on, and checked luggage. A carry on is what goes in the overhead bin, while a personal item goes under the seat. If you have medical equipment or a diaper bag, these are generally allowed in addition to your personal item, but it is always wise to check the latest FAA luggage safety guidelines for the most up to date information on exceptions.

By following these guidelines and choosing high quality gear like the bags from Luhxe, you can navigate the Allegiant carry on bag size rules with ease. Whether you are heading out for a quick weekend getaway or a week long business trip, the right preparation ensures that your focus remains on the journey rather than the logistics of your luggage.
