Frontier Airlines Baggage Fees: What Is Free, What You Pay, and When to Buy

Quick Answer: Does Frontier Include a Free Bag?

Yes. Every Frontier ticket includes one free personal item. The personal item must fit within 18 × 14 × 8 inches, including handles, wheels and straps, and must fit under the seat in front of you. Carry-on and checked bags are not included with every fare and can be purchased separately or included with certain Frontier bundles and Elite benefits.

There is no single Frontier Airlines baggage fee that applies to every flight. Bag prices vary according to your travel dates and when you purchase the bag. Frontier states that buying bags during booking gives you the lowest price, while airport and gate prices are higher.

So, if you are trying to spend as little as possible, the basic rule is simple: use the free personal item if it is enough for your trip, and if you need another bag, compare the price of buying it early with the cost of a bundle.

Frontier baggage fees can change by itinerary, purchase timing, fare and other conditions. Check the current price for your specific reservation before traveling.

Frontier’s current baggage information confirms that every ticket includes one personal item, while carry-on and checked bags can be purchased individually or through bundles. Frontier allows up to six checked bags per passenger, although operational limitations can reduce the number accepted on a particular flight. 

What Is the Free Frontier Personal Item?

Your personal item is the one bag you can bring free on every Frontier ticket. It must be no larger than 18 × 14 × 8 inches and must fit under the seat in front of you. The 35-pound maximum includes the item itself, including its handles, wheels and straps.

Examples include:

• Small backpacks
• Purses
• Totes
• Laptop or computer bags
• Briefcases
• Kids’ backpacks

Frontier says the size of your personal item can be checked during boarding. If it exceeds the permitted dimensions, an additional charge may apply.

If everything you need fits into a compliant personal item, you can avoid a baggage charge altogether. This can work well for a short trip when you can pack lightly.

Is a Carry-On Free on Frontier?

Not with every Frontier fare. A carry-on is an additional purchase unless it is included with your selected bundle or qualifying Elite benefit.

A Frontier carry-on can measure up to 24 × 16 × 10 inches, including handles, wheels and straps, and can weigh up to 35 pounds. It must fit in the overhead bin or under the seat as applicable.

Frontier allows one personal item and one carry-on per passenger when the carry-on has been purchased or is included with the fare or status benefit.

How Much Does a Frontier Carry-On Cost?

There is no universal Frontier carry-on price. Frontier says carry-on prices vary based on your travel dates and when you purchase the bag. The airline’s current guidance recommends using its Bag Price Checker for the most accurate price for your trip.

Frontier also states that buying the carry-on during booking gives you the best available price compared with waiting until the airport.

For more information about what you can bring into the cabin and the check-in process, see our [Frontier Airlines carry-on and check-in guide].

Frontier Checked Baggage: Size, Weight and Fees

A standard Frontier checked bag must not exceed 62 linear inches and must weigh 40 pounds or less. . Linear inches mean the total of the bag’s length, width and height.

For example:

Length + width + height = total linear inches

Frontier’s current Bag Options page lists the standard checked-bag limit as 62 linear inches and up to 40 pounds. Some bundles or Elite benefits can provide a higher weight allowance.

How Much Does Frontier Charge for Checked Baggage?

The price of a Frontier checked bag depends on your itinerary and when you purchase it. Frontier does not publish one fixed checked-bag price that applies to every passenger. Instead, the airline directs travelers to its Bag Price Checker to see the applicable price for their trip.

The important timing rule is straightforward:

• During booking: lowest available baggage pricing
• Before departure: prices may be higher
• At the airport: higher pricing applies
• At the gate: baggage can be the most expensive option

Frontier specifically advises travelers to buy bags early to save money.

If you are comparing baggage costs across airlines, our [Airline Baggage Fees Hub] can help you see how Frontier compares with other carriers.

When Is Frontier Baggage Cheapest?

The cheapest time to buy a Frontier carry-on or checked bag is during your initial booking. Frontier says baggage prices increase the closer you get to departure, with airport pricing higher than advance purchase pricing.

Instead of relying on a fixed price chart, think about Frontier’s pricing this way:

When you buy	What to expect
During booking	Lowest available baggage price
After booking online	Price may be higher
At the airport	Higher price
At the gate	Generally the most expensive option

Because the actual amount varies, check your reservation rather than relying on a generic online baggage-price range.

Frontier Baggage Bundles: When Are They Worth It?

A Frontier bundle can make sense when you need more than the free personal item and also want other travel benefits. Frontier’s current bundles combine different products such as bags, seat assignments and boarding benefits.

The current bundle structure includes:

Bundle	Baggage included	Other key benefits
Basic fare	Personal item	Additional bags available for purchase
Economy	Personal item + carry-on	Standard seat assignment and other bundle benefits
Premium	Personal item + carry-on	Premium seat and early boarding benefits
Business	Personal item + carry-on + 2 checked bags	Up to 6 per passenger, subject to operational limitations

Frontier’s Business bundle currently includes two checked bags of up to 50 pounds each per person, per direction, subject to the bundle terms shown during booking. 

This means you should compare the total bundle price with the cost of your base fare plus the individual bags and other options you actually need.

For example, if you need a carry-on and a seat assignment, an Economy bundle may be worth comparing with purchasing those options separately.

For information about how the bundles affect your seat, see our [Frontier Airlines seat selection and upgrade guide].

Frontier Airlines Baggage Allowance for Elite Members

Eligible Frontier Miles Elite members receive baggage benefits based on their status level. The current Frontier policy lists the following baggage benefits:

• Elite Silver: Personal item
• Elite Gold: Carry-on for the member
• Elite Platinum: Carry-on + 1 checked bag
• Elite Diamond: Carry-on + 2 checked bags

Frontier also states that the Platinum and Diamond checked-bag benefits can extend to up to eight other passengers on the same reservation, subject to the applicable terms.

If you have Frontier Elite status, check your benefits before paying separately for baggage.

Frontier Overweight Baggage Fees

A standard Frontier checked bag is limited to 40 pounds, so a heavier bag can incur an additional overweight charge.

For current bookings, Frontier lists:

Checked-bag weight	Additional fee
41–50 lb	$75 per bag, per direction
51–99.99 lb	$129 per bag, per direction for bookings made on or after April 4, 2026
Over 100 lb	Not accepted

For bookings made before April 4, 2026, Frontier lists a $100 fee per bag, per direction for bags weighing 51–99.99 lb.

These overweight charges are in addition to the applicable checked-bag fee. Frontier also notes that assistive devices can be subject to different rules.

If your bag is close to the 40-pound limit, weighing it at home can help you avoid an unexpected surcharge.

Frontier Oversized Baggage Fees

A checked bag becomes oversized when it exceeds 62 linear inches. Frontier currently charges an additional $75 per bag, per direction for bags measuring between 63 and 110 linear inches. Bags over 110 linear inches are not accepted, except for certain assistive devices.

Remember that linear inches are calculated as:

Length + width + height

If your suitcase measures 30 × 20 × 15 inches, for example, its total is 65 linear inches and it falls into Frontier’s oversized range.

If a bag is both overweight and oversized, the applicable charges can both apply. Check Frontier’s current optional-services terms for the rules that apply to your specific item.

Can I Add Baggage After Booking?

Yes. Frontier allows passengers to purchase bags after the original booking through FlyFrontier.com or the Frontier app. Frontier’s FAQ says customers can purchase seats and bags during the initial booking or anytime afterward.

A simple way to manage your baggage is:

1. Open your Frontier reservation.
2. Go to your trip or booking details.
3. Select the option to add bags.
4. Choose the baggage you need.
5. Review the current price before paying.

The key point is not to wait until the airport if you already know you need a bag. Frontier states that baggage is cheaper when purchased earlier.

If you need assistance with a booking or baggage issue, our [Frontier Airlines customer service guide] explains the available support options.

How Many Bags Can I Take on Frontier?

You can bring one personal item and, when purchased or included, one carry-on. Frontier allows up to six checked bags per trip, although operational restrictions can reduce that number on some flights.

This does not mean that six checked bags are included with your ticket. Each checked bag is subject to the applicable fare, baggage pricing and restrictions.

If you need multiple checked bags, check the price for each bag in your reservation before completing your purchase.

What About Children, Strollers and Special Items?

Some items have different rules from ordinary passenger baggage.

Frontier’s current baggage information identifies certain essential baby gear and assistive devices as eligible for special treatment. For example, Frontier’s optional-services information states that a stroller and car seat may be checked free when traveling with a child, while a diaper bag may be carried on free of charge when traveling with a child.

Special rules can also apply to:

• Wheelchairs and mobility devices
• Medical equipment
• Sporting equipment
• Musical instruments
• Strollers and car seats
• Other special items

Do not assume that a sports item or oversized piece of equipment follows the same rules as an ordinary suitcase. Check Frontier’s special-item policy for the specific item before traveling.

Sports Equipment and Musical Instruments

Sports equipment and musical instruments can have baggage rules that differ from ordinary checked bags. Some items may be subject to standard checked-bag charges, while others can also attract overweight or oversized fees.

Frontier’s current optional-services information specifically notes that items such as golf equipment, skis and snowboards are subject to applicable checked-baggage and overweight rules, while other special items may also be subject to oversized charges.

If you are traveling with specialized equipment, check the rules for that item before adding it to your reservation.

What Is the Cheapest Way to Fly With Baggage on Frontier?

The cheapest option depends on how much you need to bring.

If you can pack light

Use the free personal item and avoid purchasing additional baggage.

If you need an overhead bag

Compare the price of a carry-on purchased during booking with the Economy, Premium or Business bundle.

If you need checked luggage

Check the price of the bag during booking and compare it with any bundle that includes checked baggage.

If you need multiple bags

The Business bundle may be worth comparing because Frontier currently includes two checked bags with a 50-pound allowance each in that bundle.

There is no single option that is cheapest for every passenger. Your best choice depends on your fare, number of travelers, number of bags and other services you need.

Practical Examples

Example 1: Weekend traveler with one small backpack

A traveler is going away for two nights and can fit everything into a bag measuring less than 18 × 14 × 8 inches.

Best option: Use the free personal-item allowance and avoid buying a carry-on or checked bag.

Example 2: Traveler who needs an overhead suitcase

The traveler needs more space than a personal item but does not want to check luggage.

Best option: Purchase a carry-on during booking and compare its price with the Economy bundle.

Example 3: Traveler with a 43-pound suitcase

The suitcase fits within the 62-linear-inch size limit but weighs 43 pounds.

Result: It exceeds Frontier’s standard 40-pound checked-bag limit and falls into the 41–50-pound overweight category, which currently carries a $75 additional charge per bag, per direction.

Example 4: Family needing multiple bags

A family needs carry-ons, checked luggage and assigned seats.

Best option: Compare the total cost of individual baggage and seat purchases with the applicable Frontier bundle. A bundle can be more useful when several included benefits match what the family already needs.
