Every Allegiant passenger can bring one free personal item, while carry-on bags and checked luggage require an additional fee. Understanding the Allegiant baggage policy before your flight helps you avoid unexpected airport charges, choose the right baggage option, and travel with confidence.

• Not block the aisle.

Examples of items that usually qualify:

• Small backpack
• Purse
• Laptop bag

A personal item is the only baggage allowance included in a standard Allegiant ticket.

Allegiant Carry-On Size and Dimensions Explained

Passengers who need overhead storage must purchase a carry-on bag.

The official Allegiant carry on size is: 10 x 16 x 22 inches (25cm x 40cm x 55cm)

Allegiant Carry-On Bag Size vs Personal Item Size

Understanding the difference between a personal item and carry-on helps you avoid extra fees and pack smarter. Check the Allegiant carry on bag size limits before choosing the right luggage option. 

Feature	Personal Item	Carry-On Bag
Included Free	Yes	No
Storage Location	Under seat	Overhead bin
Size Limit	8 x 14 x 18 inches	10 x 16 x 22 inches
Additional Fee	No	Yes
Best For	Small essentials	Larger cabin luggage

The biggest difference is where the bag is stored. Personal items go under the seat, while carry-ons use overhead bin space.

Does Allegiant Charge for Carry-On Bags?

Yes, Allegiant charges for carry-on bags.

The airline's pricing model separates the basic ticket fare from optional services. Since overhead bin space is considered an additional service, passengers must pay for a carry-on bag.

Travelers who need a carry-on should add it during booking or before arriving at the airport because last-minute airport fees are usually higher.

Allegiant Carry-On Price: What Travelers Should Know

The Allegiant carry on price varies depending on:

• Flight route
• Travel dates
• Demand
• Purchase timing

A general rule:

When You Buy	Expected Cost Level
During initial booking	Lowest
Before departure online	Usually lower
Airport counter	Higher
Gate	Highest

Buying baggage in advance is usually the easiest way to save money.

Allegiant Checked Bag Weight and Size Limits

Before packing, it's important to understand the Allegiant checked bag size requirements along with the airline's weight restrictions to avoid unexpected baggage fees at the airport. Allegiant strictly enforces its checked baggage policy, so weighing and measuring your luggage before leaving home can save both time and money.

Checked Bag Rule	Limit
Maximum Weight	50 lbs (22 kg) per checked bag
Maximum Size	80 linear inches (length + width + height)
Maximum Checked Bags	Up to 5 checked bags per passenger
Online Booking Limit	Reserve up to 4 checked bags online
Overweight Bags	Additional charges apply
Oversized Bags	Oversized baggage fees apply
Maximum Accepted Weight	Bags over 99 lbs (45 kg) are not accepted

How to Measure Your Checked Bag

To calculate your bag's size, add its length, width, and height.

Example:
30 inches + 20 inches + 12 inches = 62 linear inches

Since 62 linear inches is below the 80-linear-inch limit, the bag meets Allegiant's checked baggage size requirement.

Important Tips

• Weigh your suitcase before heading to the airport to avoid overweight baggage fees.
• Leave a little extra room in your luggage, as last-minute items can easily push your bag over the allowed weight or size.
• Extra fees apply for overweight, oversized, excess bags, and sporting equipment.
• Add checked and carry-on bags during booking or through Manage Travel to pay lower baggage fees than at the airport.

Packing within these limits helps you avoid unnecessary baggage fees. 

Allegiant Excess Baggage and Overweight Bag Fees

If your luggage exceeds Allegiant's carry-on or checked baggage limits, additional fees may apply. The charges vary based on when you purchase your baggage and whether your bag is overweight or oversized.

Carry-On Baggage Fees

Fee Type	Charge
Carry-on (booked in advance)	$10–$75
Carry-on (before departure)	~$70
Carry-on (at the airport)	~$75
Oversized carry-on or personal item	$50–$75

Overweight Checked Bag Fees

Bag Weight	Fee
51–70 lbs (22–32 kg)	$50
71–99 lbs (33–44 kg)	$75

Note:

Baggage fees vary by route and booking time and may change without notice. Always verify the latest charges on Allegiant's official website before travel.

How to Save on Allegiant Baggage Fees

Planning ahead is the easiest way to avoid unnecessary baggage charges. A few simple packing strategies can help you save money before you arrive at the airport.

• Book Baggage Early – Add your bags during booking or before departure for the lowest fees.
• Travel With a Personal Item – Pack light for short trips and avoid baggage charges whenever possible.
• Pack Smart – Use lightweight clothing, avoid duplicate items, and stay within size and weight limits.
• Keep Checked Bags Under 50 lbs – Avoid overweight baggage fees by weighing your luggage before leaving home.
• Measure Your Bags – Check your bag dimensions to prevent oversized baggage charges.
• Share Luggage – Families and groups can reduce costs by sharing checked bags instead of bringing extra luggage.

Common Allegiant Baggage Mistakes That Increase Your Travel Cost

Many travelers pay extra baggage fees because they misunderstand the rules. Checking the Allegiant baggage weight limits before you pack can help you avoid unexpected charges and enjoy a smoother airport experience.

1. Assuming Carry-On Bags Are Free

A common misunderstanding is thinking that every airline includes cabin luggage. Under the Allegiant baggage policy, only one personal item is free. A standard carry-on bag requires an additional fee.

2. Buying Baggage at the Airport

Airport baggage prices are usually higher than online purchases. Adding your baggage allowance during booking or before your travel date is generally the better option.

3. Ignoring Bag Measurements

A suitcase may look small but still exceed the airline's limits. Before arriving at the airport, always check the:

• Carry on dimensions
• Personal item size
• Checked bag size

4. Packing a Checked Bag Too Close to the Weight Limit

A suitcase packed exactly at 50 pounds can become overweight after adding small items. Keeping a small weight buffer can prevent unexpected fees.

5. Confusing Personal Items With Carry-On Bags

A larger backpack, shopping bag, or small suitcase may not qualify as a personal item. If it does not fit under the seat, it may require a paid carry-on allowance.

Carry-On vs Checked Bag: Which Option Is Better?

Choosing between a carry-on and checked bag depends on your travel style, trip length, and budget.

Category	Personal Item	Carry-On Bag	Checked Bag
Cost	Free	Paid	Paid
Location	Under seat	Overhead bin	Aircraft cargo area
Best For	Short trips	Cabin travelers	Longer trips
Size Limit	8 x 14 x 18 inches	10 x 16 x 22 inches	80 linear inches
Weight Limit	No published limit	No published limit	50 lbs

Can You Add a Checked Bag After Booking Allegiant?

Yes, passengers can add checked baggage after booking.

You can usually manage baggage through your reservation before departure. Adding baggage earlier is generally more affordable than waiting until airport arrival.

For travelers who are unsure about luggage needs, reviewing baggage requirements before the flight date can prevent last-minute expenses.

Understanding the Allegiant baggage policy before your journey is the easiest way to avoid unnecessary fees and travel confidently. Remember the key rules: one free personal item, paid carry-on and checked baggage, a 50-pound checked bag limit, and an 80-linear-inch size restriction.
