Planning a trip with Allegiant Air in 2026? As an ultra-low-cost carrier, Allegiant keeps base fares affordable by charging separately for additional services—and baggage is one of the biggest factors that can increase your travel costs if you’re not prepared.
Understanding the Allegiant Airlines baggage policy before you arrive at the airport is crucial. Showing up with an oversized carry-on or an overweight suitcase can lead to unexpected fees that might double the cost of your ticket.
This comprehensive guide breaks down everything you need to know for 2026, including size limits for carry-ons, checked baggage fees, rules for special items, and expert tips to avoid extra charges.

Introduction: Why Knowing Allegiant’s Rules Matters

Allegiant Airlines operates differently than major carriers like Delta or American. Because they are an "unbundled" airline, the price you see for your seat typically only includes a personal item. Everything else—from a carry-on bag to a checked suitcase—comes with an additional fee.
The worst time to learn about these fees is at the boarding gate, where you could be forced to check an oversized bag at a premium price. By familiarizing yourself with the Allegiant Airlines baggage fees for 2026 now, you can pack smarter, prepay online, and save significant money.
Whether you're heading to Las Vegas, Florida, or a national park gateway city, knowing the exact dimensions and costs ensures a smoother, cheaper journey. If you are traveling with something unusual or simply want to confirm your bag fits the limits, don't hesitate to reach out. Travel experts at airfarepolicies are available at +1-855-869-7071 to guide you through the process.
Allegiant Airlines Carry-On Allowance
One of the most common points of confusion for Allegiant passengers is the difference between a personal item and a carry-on bag. Unlike legacy carriers, Allegiant charges a fee for standard carry-on bags that go in the overhead bin.
Personal Item (Free)
Every passenger is allowed one personal item free of charge. This item must fit entirely underneath the seat in front of you.
Max Dimensions: 7" x 15" x 16" (inches)
Examples: A purse, small backpack, laptop bag, or briefcase.
2026 Tip: Ensure your "personal item" isn't overstuffed. If it bulges out of the sizer box at the gate, you may be charged a carry-on fee plus a gate handling charge.
Carry-On Bag (Fee Applies)
If you need access to items during the flight or prefer not to check a bag, you can bring a standard carry-on, but you must pay for it.
Max Dimensions: 22" x 14" x 9" (including wheels and handles)
Weight Limit: Allegiant does not enforce a weight limit for carry-on bags (as long as you can lift it yourself).
Cost: Fees vary based on when you purchase.
Cheapest: During initial booking online.
Moderate: Pre-purchasing in the "Manage Travel" section before check-in.
Most Expensive: At the airport ticket counter or gate.
Oversized Carry-On Fees
If your carry-on exceeds the 22" x 14" x 9" limit, it must be checked to the baggage compartment. If discovered at the gate, you will face a hefty oversized baggage fee plus the standard carry-on charge. This is why it is vital to measure your bag before leaving home.
If you are unsure whether your new suitcase meets the Allegiant Airlines bag size limit, you can call airfarepolicies at +1-855-869-7071 for advice on measuring and compliance.
Allegiant Airlines Checked Baggage Rules
For longer trips or when you need to pack liquids or larger items, checking a bag is the way to go. However, the Allegiant Airlines checked baggage rules are strictly enforced regarding weight.
Weight and Size Limits
Weight Limit: 40 lbs (18.1 kg) per bag. Note: This is lower than many other airlines' 50 lb limit.
Size Limit: The total linear dimensions (length + width + height) must not exceed 80 inches.
Quantity: You can check up to 4 bags per passenger, subject to availability and fees.
Checked Baggage Fees (2026 Outlook)
Allegiant’s fees are not flat; they vary by route and demand. However, the structure remains consistent. You save the most money by paying during initial booking.
Bag TypePaid Online (During Booking)Paid at Airport (Ticket Counter)First Checked Bag$20 - $30$40 - $50Second Checked Bag$30 - $40$50 - $60Third/Fourth Bag$50+ (each)$75+ (each)
Note: Prices are estimates and subject to change based on specific flight routes and dates in 2026.
Extra Baggage Fees: Overweight and Oversized
Because Allegiant has a lower standard weight limit (40 lbs), passengers frequently incur Allegiant Airlines overweight baggage fees. It is essential to weigh your suitcase on a home scale before heading to the airport.
Overweight Fees:
41 to 50 lbs: A significant surcharge (often $50) is added on top of the standard checked bag fee.
51 to 70 lbs: An even higher surcharge is applied (often $75+).
71 to 100 lbs: Must be shipped as cargo; not accepted as standard checked baggage.
Oversized Fees:
Bags exceeding 80 linear inches will incur an oversized surcharge, typically starting around $75.
Important: If your bag is both overweight and oversized, you will pay both penalties. This can quickly turn a $30 bag into a $150 bag. To avoid these steep Allegiant Airlines extra baggage fees, consider shipping heavy items ahead of time or distributing weight across multiple bags (paying for a second checked bag is often cheaper than paying an overweight fee on one bag).
If you are trying to calculate whether it is cheaper to pay for a second bag or an overweight fee, call airfarepolicies at +1-855-869-7071 for a cost breakdown based on your specific route.
Special Items & Exceptions
The standard baggage rules don't always apply to sports gear or medical equipment. Here is how the Allegiant Airlines baggage policy 2026 handles special items.
Sports Equipment
Allegiant allows sporting equipment (like golf bags, skis, and bicycles) but counts them as standard checked bags if they fit within the size limits. However, they often have specific packaging requirements.
Golf: A golf bag containing clubs and shoes is usually accepted as a standard checked bag, provided it is within the 40 lb limit. If it weighs more, overweight fees apply.
Skis/Snowboards: One pair of skis with poles and boots in a suitable container counts as one checked bag.
Bicycles: Bikes must have the handlebars turned sideways, pedals removed, and tires deflated. A $75 fee often applies in addition to standard baggage charges.
Musical Instruments
Small instruments that fit in the overhead or under the seat can be brought as a carry-on or personal item (space permitting). Larger instruments require purchasing a seat for the instrument or being checked at the counter.
Medical Devices and Service Animals
Medical Devices: Wheelchairs, walkers, and CPAP machines are transported free of charge. It is highly recommended to gate-check these items.
Service Animals: Qualified service animals fly for free in the cabin. They do not count toward your baggage allowance. Emotional support animals are now subject to the standard pet policy (which requires a fee and travel in a kennel in the cargo hold).
Unaccompanied Minor Baggage
Children traveling as unaccompanied minors are subject to the same Allegiant Airlines checked baggage rules as adults. They are allowed one carry-on (fee applies) and one personal item. There are no special baggage allowances or waivers for minors, though the escort escorting them through the airport may assist with their bags.
How to Avoid Baggage Fees on Allegiant
Allegiant is known for ancillary revenue, but a smart traveler can minimize or avoid these costs. Here are four strategies to beat the Allegiant Airlines baggage fees in 2026.
1. Master the Personal Item
The number one way to avoid fees is to maximize your free personal item. A 7" x 15" x 16" bag is bigger than it sounds. You can fit several days' worth of clothing in a well-packed backpack if you use compression cubes. By skipping the paid carry-on and the checked bag, you save $40–$60 round trip.
2. Always Prepay Online
Never wait until you get to the airport to pay for bags. The difference between the online price and the airport price is often double. After booking your flight, immediately go to the "Manage Travel" section on Allegiant.com to add your bags to the reservation.
3. Invest in a Portable Luggage Scale
Since Allegiant’s weight limit is only 40 lbs, a cheap handheld luggage scale is a worthwhile investment. Weigh your bag at home. If it’s 42 lbs, remove a heavy jacket or a pair of shoes to wear on the plane instead of paying the $50 overweight fee.
4. Check for Bundles or Memberships
When booking, compare the fare difference. Sometimes, adding the "Bundle" (which includes a carry-on, checked bag, seat assignment, and priority boarding) is only marginally more expensive than buying a carry-on and checked bag separately. Also, Allegiant offers a credit card that sometimes includes a free checked bag as a perk.
