Frontier Airlines is known for low base fares, but bags are not always included in the ticket price. If you are planning to carry more than a small personal item, understanding the Frontier checked bag fee, size limit, and weight limit can help you avoid expensive airport charges.
Frontier Airlines checked bags usually cost less when added during booking and become more expensive closer to departure. A standard checked bag on Frontier must stay within 62 linear inches and 40 lbs. Bags heavier than 40 lbs may be charged overweight baggage fees, and bags larger than 62 linear inches may be charged oversized baggage fees.

Quick Answer: How Much Is a Checked Bag on Frontier?
A checked bag on Frontier Airlines usually costs around $53–$63 when added during booking, but the price may increase at check-in, at the airport counter, or at the gate. The final Frontier checked bag fee depends on your route, travel date, and when you purchase baggage.
Here is the simple answer:
| Frontier bag rule | 2026 limit / fee |
|---|---|
| Standard checked bag size | 62 linear inches |
| Standard checked bag weight | 40 lbs |
| 41–50 lbs overweight fee | $75 per bag, per direction |
| 51–99.99 lbs overweight fee | $129 for bookings made on or after April 4, 2026 |
| Oversized checked bag | $75 for 63–110 linear inches |
| Bag over 100 lbs | Not accepted |
| Bag over 110 linear inches | Not accepted |
The cheapest way to pay for checked baggage on Frontier is to add your bag online during booking. Waiting until the airport or gate can make the same bag much more expensive.
Frontier Airlines Baggage Fees 2026
Frontier baggage fees are not fixed for every passenger. They can change based on the route, travel date, and purchase timing. In most cases, the earlier you add your bags, the less you pay.
Here is a general Frontier baggage fee breakdown:
| Bag type | During booking | Online check-in | Airport counter | Gate |
|---|---|---|---|---|
| Personal item | Free | Free | Free | Free |
| Carry-on bag | Paid add-on | Higher than booking | Higher | Highest |
| First checked bag | Around $53–$63 | Usually higher | Higher | Up to around $117 |
| Second checked bag | Around $53–$63 | Usually higher | Higher | Up to around $117 |
| Third or additional checked bag | Usually higher | Usually higher | Usually higher | Usually higher |
Frontier includes one free personal item with every fare. Carry-on bags and checked bags are usually paid add-ons unless you buy a bundle, have eligible elite status, qualify for a special benefit, or book a fare that includes baggage.
Important: Always check Frontier’s Bag Price Checker before booking because Frontier bag prices can vary by route and date.
Frontier Checked Bag Size Limit
The standard Frontier checked bag size limit is 62 linear inches.
Linear inches means:
Length + Width + Height
This measurement includes handles, wheels, and straps. If your bag measures more than 62 linear inches, Frontier may treat it as an oversized bag and charge an extra oversized baggage fee.
Frontier checked bag size rules:
| Checked bag type | Size limit |
|---|---|
| Standard checked bag | Up to 62 linear inches |
| Oversized checked bag | 63–110 linear inches |
| Over 110 linear inches | Not accepted |
Frontier’s oversized baggage fee is usually $75 per bag, per direction for bags between 63 and 110 linear inches.
A bag over 110 linear inches is not accepted as checked baggage.
Frontier Checked Bag Weight Limit
The standard Frontier checked bag weight limit is 40 lbs.
This is important because many major U.S. airlines allow checked bags up to 50 lbs before overweight charges begin. Frontier’s limit is stricter. If your bag weighs more than 40 lbs, you may have to pay an overweight baggage fee.
Frontier checked bag weight rules:
| Bag weight | Fee / rule |
|---|---|
| Up to 40 lbs | Standard checked bag |
| 41–50 lbs | $75 overweight fee |
| 51–99.99 lbs | $129 for bookings made on or after April 4, 2026 |
| 100 lbs or more | Not accepted |
If your checked bag is both overweight and oversized, Frontier may charge both fees. That means you pay the standard checked bag fee plus the overweight fee plus the oversized fee.
Example:
If your checked bag weighs 45 lbs and measures 65 linear inches, you may pay the standard checked bag fee, a $75 overweight fee, and a $75 oversized fee.
Frontier Overweight and Oversized Baggage Fees
Frontier overweight baggage fees are charged when your checked bag weighs more than 40 lbs. Oversized baggage fees are charged when your checked bag is larger than 62 linear inches.
| Situation | Frontier baggage fee |
|---|---|
| Checked bag weighing 41–50 lbs | $75 per bag, per direction |
| Checked bag weighing 51–99.99 lbs | $129 for bookings made on or after April 4, 2026 |
| Checked bag over 100 lbs | Not accepted |
| Checked bag measuring 63–110 linear inches | $75 per bag, per direction |
| Checked bag over 110 linear inches | Not accepted |
These fees are added on top of the regular checked bag fee. They do not replace the original baggage charge.
For example, if your first checked bag costs $63 and it is overweight by 5 lbs, you may pay $63 + $75. That makes the total $138 for that one bag, one way.
This is why it is always better to weigh your luggage before leaving for the airport.
Frontier Airlines Baggage Size and Weight Limits
Frontier Airlines baggage size and weight limits are different for personal items, carry-on bags, and checked bags.
| Bag type | Maximum size | Maximum weight | Cost |
|---|---|---|---|
| Personal item | 14 x 18 x 8 inches | No listed weight limit | Free |
| Carry-on bag | 24 x 16 x 10 inches | 35 lbs | Paid add-on |
| Standard checked bag | 62 linear inches | 40 lbs | Paid add-on |
| Oversized checked bag | 63–110 linear inches | 40 lbs before overweight fees | Extra $75 fee |
| Overweight checked bag | 62 linear inches | 41–99.99 lbs | Extra $75–$129 fee |
Your personal item must fit under the seat in front of you. Your carry-on bag must fit in the overhead bin or under the seat and stay within Frontier’s carry-on size and weight limit.
Is a Backpack Free on Frontier Airlines?
Yes, a backpack can be free on Frontier Airlines if it fits within Frontier’s personal item size limit.
Frontier’s free personal item size is:
14 x 18 x 8 inches
A small backpack, laptop bag, purse, tote, or briefcase can usually count as a free personal item if it fits fully under the seat in front of you.
But if your backpack is too large, Frontier may charge it as a carry-on bag. This can become expensive at the gate, so check the size before your flight.
Tip: Do not overpack a soft backpack. Even if the bag is close to the allowed size, stuffing it too much can make it difficult to fit into the Frontier bag sizer.
Does Frontier Allow a Free Carry-On Bag?
Frontier does not usually include a free carry-on bag with the basic fare. Every passenger gets one free personal item, but a carry-on bag is usually a paid add-on.
A Frontier carry-on bag must stay within:
24 x 16 x 10 inches
It must also weigh no more than 35 lbs.
You can add a carry-on bag during booking, after booking through Manage Trip, during online check-in, at the airport, or at the gate. However, buying it early is usually cheaper than paying at the airport.
Why Are Frontier Bag Fees So Expensive?
Frontier follows an ultra-low-cost airline model. That means the base fare may look very cheap, but extras like bags, seat selection, and priority boarding are charged separately.
This model can work well for travelers who pack light. If you only travel with one free personal item, Frontier can still be very affordable.
But if you add:
- a carry-on bag
- checked baggage
- seat selection
- overweight baggage fees
- airport counter charges
…the final price may become similar to other airlines.
That is why you should always compare the total trip cost, not just the base ticket price.
Is Frontier Still Cheap After Baggage Fees?
Frontier can still be cheap after baggage fees, but only in the right situation.
It may still be a good deal if:
- You travel with only a free personal item.
- You add checked baggage during booking.
- You avoid paying for seat selection.
- You do not wait until the airport to buy bags.
- You compare the final price before booking.
Frontier may not be the cheapest option if:
- You need both a carry-on and checked bag.
- Your bag may cross the 40 lb checked bag weight limit.
- You are traveling with family and each person needs baggage.
- You pay for bags at the gate.
- You choose multiple extras separately.
Before booking, compare the full fare with baggage included. Sometimes a slightly higher ticket on another airline may cost less overall if it already includes more baggage allowance.
How to Add a Checked Bag to Your Frontier Flight
You can add checked baggage to a Frontier Airlines flight online before departure.
Here is how to add a checked bag:
- Go to Frontier’s official website or app.
- Open the “Manage Trip” or “Check-In” section.
- Enter your last name and confirmation code.
- Select “Add Baggage.”
- Choose the number of checked bags.
- Pay the baggage fee online.
- Check your email confirmation.
You can also add bags during online check-in. However, the best time to add checked baggage is during the original booking process because Frontier baggage fees are usually lower at that stage.
Frontier Bundles: Are They Better Than Buying Bags Separately?
Frontier bundles can help travelers save money when they need more than a personal item. Instead of buying bags, seats, and flexibility separately, a bundle combines travel extras into one package.
Frontier’s main bundle options may include:
| Bundle type | What it usually includes |
|---|---|
| Economy Bundle | Personal item, carry-on bag, standard seat selection, no change/cancel fee |
| Premium Bundle | Economy benefits plus premium seat and early boarding with overhead bin space |
| Business Bundle | Premium benefits plus 2 checked bags and UpFront Plus seat |
The Business Bundle can be useful if you need checked baggage because it may include two checked bags. Frontier says bundle benefits can vary, so check the exact inclusions during booking.
A bundle may be worth it if you need:
- a carry-on bag
- checked baggage
- seat selection
- more flexibility
- early boarding
- overhead bin space
But if you only need one checked bag and no seat selection, compare the bundle price with the individual bag fee before paying.
Who Gets Free Bags on Frontier Airlines?
Most standard Frontier passengers do not get free checked bags. However, some travelers may qualify for free baggage benefits.
| Passenger type | Free carry-on? | Free checked bags? |
|---|---|---|
| Standard passenger | No | No |
| Passenger with only personal item | Personal item only | No |
| Eligible bundle passenger | Depends on bundle | Depends on bundle |
| Business Bundle passenger | Carry-on included | 2 checked bags may be included |
| Active-duty U.S. military | Usually eligible for baggage benefits | Usually eligible for baggage benefits |
| Passenger with mobility device | Assistive device free | Assistive device free |
| Parent traveling with infant | Diaper bag / stroller rules may apply | Stroller and car seat may be checked free |
Frontier baggage benefits can depend on fare type, status, card benefits, bundle, and route. Always check the baggage allowance shown in your booking before your flight.
Frontier Checked Bag Policy for Special Items
Frontier may accept sports equipment, musical instruments, strollers, car seats, and medical devices, but fees depend on the item and its size or weight.
Common special item rules:
- Strollers and car seats can usually be checked or gate-checked without an extra baggage fee.
- Assistive devices like wheelchairs, walkers, and medical devices are usually carried free of charge.
- Sports equipment may count as checked baggage if it meets standard size and weight limits.
- Oversized sports items may receive an oversized baggage fee.
- Musical instruments may be carried on if they fit within the carry-on size limit and space is available.
If your item is large, heavy, fragile, or unusual, check Frontier’s official special items policy before traveling. If you need help with baggage or booking your Frontier flight reservations, reach out to us at our phone today!
5 Ways to Save on Frontier Baggage Fees
Frontier baggage fees can add up quickly, but you can reduce the cost with a few smart steps.
1. Buy bags during booking
This is usually the cheapest time to add baggage. Frontier baggage fees often increase after booking, during check-in, at the airport, and at the gate.
2. Travel with only a personal item
If your trip is short, pack inside a personal item that fits within 14 x 18 x 8 inches. This helps you avoid carry-on and checked bag fees completely.
3. Weigh your checked bag at home
Frontier’s checked bag weight limit is 40 lbs. A bag that weighs 41 lbs can trigger an overweight fee. Use a luggage scale before leaving for the airport.
4. Compare bundle pricing
If you need a carry-on bag, seat selection, and checked baggage, a Frontier bundle may be cheaper than buying each item separately.
5. Avoid paying at the gate
Gate baggage fees are usually among the highest. If you know you need a checked bag or carry-on bag, pay online before arriving at the airport.
Frontier Checked Bag Fee vs Other Airlines
Frontier’s checked bag fee can look affordable when purchased early, but the 40 lb weight limit is stricter than many major U.S. airlines.
Many airlines allow checked bags up to 50 lbs before charging overweight fees. Frontier starts charging overweight fees once the bag crosses 40 lbs.
This makes weight planning very important. A suitcase that would be normal on another airline may be overweight on Frontier.
If you are comparing Frontier with another airline, check:
- base fare
- carry-on fee
- checked bag fee
- seat selection cost
- overweight baggage risk
- airport baggage pricing
- bundle options
The cheapest ticket is not always the cheapest trip.
