Frontier Baggage Fees 2026: Bundles, Bag Sizes and Overweight Costs

Frontier baggage fees depend on what you buy and when you buy it. Every Frontier fare includes one personal item that fits under the seat, but a carry-on bag and checked bags cost extra unless your fare bundle, elite status or military ID covers them. Frontier does not publish one flat bag price; it changes with your travel dates and how close to departure you pay, so the cheapest move is almost always to add bags when you book.

How much does a carry-on or checked bag cost on Frontier?

Frontier's own FAQ says bag prices "vary depending on your travel dates and when you purchase them," and it points travelers to its Bag Price Checker on the bag options page instead of listing a fixed fee. So any single number you see quoted elsewhere is a snapshot, not a rule. Check current bag prices for your exact dates before you book.

What Frontier does state clearly is the order of prices:

When you book: lowest price.
Later, before the airport (through Manage Trip on flyfrontier.com or the app): still cheaper than the airport.
At the airport: higher.
At the gate: highest.

Frontier also says to buy checked bags at least 60 minutes before your flight. If you think there is any chance you will need a bag, adding it during booking is the safe play, because bag purchases are generally non-refundable once made (Frontier makes exceptions when it cannot provide the service, such as after a cancellation or significant schedule change).

What each Frontier bundle includes

Bundles are Frontier's way of packaging extras with the fare. Frontier lists bundles starting from $29 per passenger, per direction, though the actual price depends on the flight.

Bundle	Personal item	Carry-on	Checked bags	Seat	Other
Basic fare (no bundle)	Included	Extra	Extra	Extra	Change and cancel fees apply
Economy	Included	Included	Extra	Standard seat	No change or cancel fee
Premium	Included	Included	Extra	Premium seat	Early boarding with overhead bin space
Business	Included	Included	2 bags, up to 50 lbs each	UpFront Plus seat	Everything in Premium

The Business bundle is the only one that includes checked bags, and it raises the weight limit to 50 lbs per bag instead of the standard 40 lbs.

When a bundle makes sense

You need a carry-on and might change plans: the Economy bundle covers the carry-on and removes change and cancel fees. On a basic fare booked on or after September 25, 2026, Frontier lists a $149 change fee inside 59 days of departure and a $149 cancellation fee.
You are checking two bags: price the Business bundle against two separate checked bags plus a seat. With the higher 50 lb limit, it can also spare you an overweight charge.
You only need a backpack: skip the bundle. The personal item is included on every fare.

Personal item rules: the one thing that is always included

Your personal item must fit under the seat in front of you and stay within 18 x 14 x 8 inches, including any wheels, handles and straps. Frontier checks size at boarding, and an item that is too big is subject to an extra charge at the gate. Frontier does not list that gate amount, which is a good reason to measure your bag at home.

Good personal item choices are a soft backpack, a tote or a slim under-seat roller. A small rolling carry-on that fits other airlines' overhead bins will usually be too deep for Frontier's 8-inch limit.

Carry-on rules

Maximum 24 x 16 x 10 inches and 35 lbs.
It must fit in the overhead bin. If bins are full, Frontier says it may gate-check your paid carry-on at no additional cost.
Coats, canes, crutches, portable oxygen concentrators, respiratory devices and assistive devices do not count toward carry-on charges.
Board First ($2.99 to $14.99 per passenger, per direction) puts you in Group 1 and guarantees overhead bin space, but it can only be added when you buy a carry-on.
Priority Boarding ($0.99 to $9.99 per passenger, per direction) boards you in Group 4.

Checked bag rules

Maximum 62 linear inches (length + width + depth) and 40 lbs, unless your bundle or status allows more.
41 to 50 lbs: $75 overweight charge each way. 51 to 99.99 lbs: $129 each way for bookings made on or after April 4, 2026.
63 to 110 linear inches: $75 oversize charge each way.
Bicycles can be checked but not carried on. For bookings made on or after May 29, 2026, Frontier lists $100 per bag, per direction.
Do not pack medication, cash, electronics, car keys, important documents or valuables in checked bags. Lithium batteries, aerosols and other hazardous items are prohibited.

Since the overweight charge starts at just 41 lbs, weigh your bag at home. Moving a few pounds into your personal item can save $75.

Who gets bags included

Frontier elite status

Status	Bags included
Elite Silver	Personal item
Elite Gold	Carry-on bag (member only)
Elite Platinum	Carry-on and 1 checked bag (member plus up to 8 on the same reservation)
Elite Diamond	Carry-on and 2 checked bags (member plus up to 8 on the same reservation)

Active-duty military

Active-duty service members get one personal item, one carry-on and two checked bags at no charge on all ticket types, with overweight and oversize charges waived on the two checked bags. An accompanying spouse and children on the same itinerary also qualify. Bring a valid Common Access Card or Armed Forces ID with an active duty, reserve, guard or academy affiliation. Frontier says military bags can be added at the airport counter or gate without an agent assistance fee.

Families with kids

Frontier says strollers and car seats can be checked at no charge, and they do not count toward your carry-on or personal item allowance. You can gate-check a stroller and get it back at your destination. To use a car seat onboard, you need to buy a seat for your child and the car seat must carry an air-travel approval label.

Other Frontier fees that catch travelers off guard

Airport agent assistance: up to $25 per passenger, per direction, whether pre-paid or not.
Seat selection: from $15 per passenger, per flight segment.
Pets in the cabin: $149 per pet, per direction.
Name change: $75 per passenger.

Tips to pay less for bags on Frontier

Decide on bags before you book. Booking is Frontier's lowest bag price, and the gate is its highest.
Pack to the personal item size. 18 x 14 x 8 inches is enough for a weekend if you pack light.
Compare the bundle, not just the fare. If you need a carry-on and a seat, the Economy bundle may cost less than adding them separately, and it drops change fees.
Weigh checked bags at home. Frontier's standard limit is 40 lbs, and charges start at 41.
Use Manage Trip if plans change. Adding a bag online before you leave still beats paying at the airport.
