Are Carry On Bags Free On Allegiant Air? | Know Before You Go

No, standard carry-on bags that fit in the overhead bin are not free on Allegiant Air; only a small personal item is included with your ticket.

Navigating airline baggage policies can feel like deciphering a secret code, especially with ultra-low-cost carriers like Allegiant Air. Understanding what’s included and what costs extra is key to a smooth trip and avoiding unexpected fees at the airport.

Allegiant’s Baggage Philosophy: The Unbundled Approach

Allegiant Air operates on an “unbundled” pricing model, which means you pay for only the services you choose. This approach allows them to offer very competitive base fares, but it also means many amenities considered standard on other airlines, like seat selection or a full-sized carry-on bag, come with an additional charge. This model empowers travelers to customize their experience and only pay for what they need.

The core idea is transparency: you see the lowest possible fare upfront, and then you add on extras like baggage, seat assignments, or priority boarding as desired. This differs significantly from traditional airlines where a carry-on bag is typically included in the base fare.

The Personal Item: Your One Free Bag

Every Allegiant Air ticket includes one free personal item. This is the only bag you can bring on board without incurring an additional fee. The personal item must be small enough to fit completely under the seat in front of you.

Common examples of personal items include a purse, a small backpack, a briefcase, or a laptop bag. The key is its size and its ability to stow without obstructing the aisle or another passenger’s space. Maximizing this free allowance is a smart strategy for budget-conscious travelers.

Personal Item Dimensions and Maximization Tips

Allegiant specifies strict dimensions for personal items. Your personal item cannot exceed 7 inches x 15 inches x 16 inches (17.8 cm x 38.1 cm x 40.6 cm). These dimensions include wheels and handles. It’s crucial to measure your bag accurately before heading to the airport.

• Pack Smart: Utilize every inch of space. Roll clothes tightly, use compression bags, and choose items that serve multiple purposes.
• Wear Bulky Items: If you’re bringing a jacket, wear it onto the plane instead of packing it. This frees up valuable space in your personal item.
• Digitalize Documents: Store boarding passes, hotel reservations, and other important papers on your phone or tablet to avoid carrying physical folders.
• Consolidate Personal Items: If you typically carry a purse and a small backpack, try to combine essentials into one bag that meets the personal item dimensions.

Carry-On Bags: When They Cost Extra

A standard carry-on bag, designed to fit in the overhead bin, is not included with your Allegiant ticket and always incurs a fee. This is a common point of confusion for travelers accustomed to other airlines where a carry-on is often free.

Allegiant defines a carry-on bag as any item that exceeds personal item dimensions but fits within the overhead compartment. These bags are subject to specific size and weight restrictions and must be purchased separately. The cost for a carry-on bag varies based on when and where you purchase it.

Purchasing Carry-On Bags and Cost Differences

The most economical way to purchase a carry-on bag on Allegiant Air is during your initial booking online. Prices typically increase if you add it later through their website, and they are significantly higher if purchased at the airport counter or, worst of all, at the boarding gate. Paying at the gate often results in the highest possible fee, so planning ahead is essential.

Allegiant’s pricing is dynamic, meaning baggage fees can vary by route and demand. Always check the exact cost for your specific flight during the booking process on their official website. The fee covers one carry-on bag per passenger.

Allegiant Baggage Fee Purchase Tiers (Example)

Bag Type	Purchase Time	Estimated Cost Range
Personal Item	N/A	Free
Carry-On Bag	Online (Initial Booking)	$15 – $35
Carry-On Bag	Online (After Booking)	$20 – $45
Carry-On Bag	Airport Counter	$50 – $65
Carry-On Bag	Boarding Gate	$75 – $100

Understanding Allegiant’s Baggage Dimensions

Adhering to Allegiant’s precise baggage dimensions is critical to avoid unexpected fees. Airlines use bag sizers at the airport, and if your bag does not fit, you will be required to pay the higher airport or gate fee for it to be checked or carried on.

For a paid carry-on bag, the maximum dimensions are 9 inches x 14 inches x 22 inches (22.9 cm x 35.6 cm x 55.9 cm), including wheels and handles. These dimensions are standard for most overhead bins. It is always a good practice to measure your bag when it’s fully packed to ensure it complies. For the most current and specific guidelines, always refer directly to the Allegiant Air official website.

The Importance of Measuring Your Bag

Many soft-sided bags can expand beyond their stated dimensions when overpacked. A bag labeled “carry-on compliant” by a manufacturer might still exceed Allegiant’s specific limits if it’s bulging. Use a tape measure to verify your bag’s height, width, and depth, including any external pockets, handles, or wheels. This small step can save you significant money and stress at the airport.

Checked Bags: An Alternative to Carry-On Fees

For travelers needing more space than a personal item allows, a checked bag can sometimes be a more cost-effective option than a paid carry-on, especially if you have multiple items. Allegiant allows up to four checked bags per passenger.

Checked bags have different size and weight restrictions. Each checked bag must not exceed 80 linear inches (length + width + height) and typically has a weight limit of 40 pounds (18 kg). Overweight or oversized bags will incur additional fees. Like carry-on bags, checked bags are cheapest when purchased online during the initial booking.

TSA Guidelines for Checked vs. Carry-On Items

When deciding between a carry-on and a checked bag, remember Transportation Security Administration (TSA) regulations. Certain items are restricted to either carry-on or checked luggage for safety reasons. For example, liquids, aerosols, and gels in carry-on bags must follow the 3-1-1 rule (containers 3.4 ounces or less, in a 1-quart-sized bag, one bag per passenger). However, larger quantities must go in checked luggage. Conversely, lithium-ion power banks and spare batteries are generally allowed only in carry-on bags, not checked luggage. According to the TSA, these batteries pose a fire risk in the cargo hold and must be accessible in the cabin.

Smart Packing Strategies for Allegiant Travelers

Efficient packing is a superpower when flying Allegiant. With strict size limits and fees for anything beyond a personal item, thoughtful preparation makes a significant difference in your travel experience and budget.

• Roll, Don’t Fold: Rolling clothes tightly saves space and can minimize wrinkles.
• Utilize Packing Cubes: These help compress items and organize your bag, making it easier to fit more.
• Wear Your Heaviest Items: If you’re bringing boots or a heavy jacket, wear them on the plane rather than packing them.
• Travel-Size Toiletries: Stick to the TSA 3-1-1 rule for liquids in your personal item. Consider solid toiletries like shampoo bars to save space and avoid liquid limits.
• Multi-Use Items: Choose clothing that can be mixed and matched, and bring versatile accessories.
• Digital Entertainment: Load movies, books, and music onto your devices instead of carrying physical copies.

Avoiding Surprises: Pre-Purchase and Verification

The best way to manage baggage fees with Allegiant Air is to be proactive. Always assume that any bag larger than a small personal item will cost extra. The moment you book your flight, consider your baggage needs and add them to your reservation. This pre-purchase step consistently offers the lowest rates.

Before every trip, take a few minutes to verify Allegiant’s current baggage policies on their official website. Policies can occasionally be updated, and staying informed ensures you’re prepared. Double-check the specific dimensions and weight limits for your personal item and any purchased bags. This diligence eliminates stress and unexpected costs at the airport, allowing you to focus on enjoying your trip.
