Frontier Carry-On Size Rules: Fees, Limits & Packing Guide (2026)
Before boarding, knowing the Frontier carry on size can save you from expensive gate charges and last-minute stress. Frontier Airlines allows one free personal item, while larger carry-on bags require payment and must meet strict size limits. This guide breaks down everything you need to know from dimensions and fees to packing tips, so you can avoid extra charges and travel without stress or confusion.
What Is the Frontier Carry On Size?
If you're wondering about Frontier’s carry on bag size, here's the short answer:
- Carry-on bag (Paid): 24 × 16 × 10 inches (61 × 40.6 × 25.4 cm)
- Maximum weight: 35 lbs (15.9 kg)
- Must fit inside the overhead bin.

Understanding Frontier Personal Item Size
Every passenger receives one free Frontier personal item with the base fare. A personal item’s dimensions, as mentioned in the table above include wheels, pockets, handles, and straps.
Examples include:
- Small backpack
- Laptop bag
- Purse
- Tote bag
- Briefcase
A backpack qualifies only if it stays within the required dimensions.
Is Frontier Strict About Carry-On Size?
Yes. Frontier is considered one of the strictest U.S. airlines when it comes to baggage checks.
Airport agents regularly ask travelers to place bags inside the official metal sizer before boarding. If a bag doesn’t fit completely, even due to wheels or an overstuffed pocket, you may have to pay a costly gate fee.
Understanding Frontier Airlines carry on size limits in advance helps avoid these unexpected charges.
To reduce the risk:
- Measure your luggage before leaving home.
- Don't overpack.
- Use soft-sided luggage if possible.
- Compress clothing using packing cubes.
Can You Bring Both a Carry-On and a Backpack?
Yes, Frontier allows bringing both the bags types, but only under certain conditions.

Frontier Checked Bag Size Rules
Before packing heavier luggage, it’s important to understand the Frontier checked bag size limits to avoid unexpected fees and ensure smooth check-in at the airport. If your luggage exceeds the carry-on limits, you will need checked baggage.
Current limits include:
- Maximum dimensions: 62 linear inches
- Maximum weight: 40 lbs
Oversized or overweight luggage results in additional fees.
If you're packing bulky clothing, sports equipment, or souvenirs, checking a bag may be more practical than paying oversized carry-on charges.
Frontier Oversize and Overweight Fees
If your bag exceeds standard size or weight limits, additional charges apply at the airport.
- 41–50 lbs: +$75
- 51–99.99 lbs: +$100
- Over 99.99 lbs: Not accepted
- 63–110 linear inches: +$75
- Over 110 linear inches: Not accepted
These charges are applied per bag and are higher at the airport compared to pre-booked baggage options. Packing within limits is the best way to avoid unnecessary costs.
How to Avoid Frontier Carry-On Fees?
You don't always have to pay for luggage. Understanding the Frontier Airlines baggage policy is essential to avoid unnecessary charges and pack smartly before your flight.
Here are the smartest ways to save money:
Pack Only a Personal Item
A carefully packed backpack that meets the Frontier personal item dimensions travels free.
Purchase Bags Early
Carry-on prices increase as your departure date approaches. Adding baggage during booking usually costs less than paying later.
Choose a Bundle
Frontier frequently offers travel bundles that combine baggage, seat selection, and flexibility for less than buying each separately.

Elite members receive complimentary baggage benefits depending on tier.
Use the Frontier World Mastercard
Eligible cardholders may receive free checked baggage benefits on qualifying bookings.
Military Benefits
Eligible active-duty U.S. military travelers receive baggage allowances, including carry-on and checked bags, subject to Frontier's policy.
How to Add a Carry-On After Booking?

If you already booked:
- Open the app or go to Manage Trip.
- Enter your last name and confirmation code.
- Hit Search.
- Select Add Seat or Add Baggage.
- Complete the payment.
If you are checking in (within 24 hours):
- Open the app or go to “My Trip” on the airline’s website.
- Enter your details (last name + confirmation code).
- Click Search.
- Start check-in and add seats or bags if needed.
Buying baggage in advance is usually cheaper.
Smart Packing Tips for Frontier Flights
Packing efficiently makes a noticeable difference on Frontier.
- Measure your luggage before every trip.
- Keep heavy shoes on your feet instead of inside your bag.
- Wear your jacket instead of packing it.
- Choose compression cubes.
- Avoid rigid suitcases if they're close to the size limit.
- Leave extra room so your bag easily fits inside the sizer.
These small habits can prevent expensive surprises at the gate.
Common Mistakes That Cost Travelers Money
Avoid these frequent errors:
- Assuming wheels don't count toward measurements.
- Overstuffing backpacks.
- Waiting until airport check-in to buy baggage.
- Ignoring the 35-pound carry-on weight limit.
- Bringing a backpack that's too large for under-seat storage.
Planning ahead is far cheaper than paying last-minute baggage fees.
