Tip: My favorite suitcase is this 20-inch Samsonite Winfield. It is a durable carry-on with a spacious interior, with spinner wheels, and is compliant with most budget and international airlines check it out on Amazon.

How Strict is Frontier With Its Carry-on Luggage Policies?

Just like the majority of US carriers, Frontier Airlines has set limits to the number of bags you can bring on board the airplane.

All frontier Airlines passengers are allowed to take on board two items of carry on baggage:

  • 1 carry on bag; subject for applicable fee
  • 1 personal item without applicable fees

Size and weight limits for carry on

Frontier didn’t have concerns about the weight of carry-on luggage as long as you can handle your suitcase without any help, but they do about the size.

So make sure that your carry-on doesn’t exceed the following size limits: 24″ in Height, 16″ in Weight, 10″ in Depth (including handles, wheels, and straps).

Frontier Carry on Liquids Policy

If you are planning to bring any types of liquids in your carry on bag, you will need to follow the TSA liquid rules.

The TSA stated that each container of liquids need to be 3.4 oz / 100 ml or less, and placed inside a quart sized bag.

You will need to remove any liquids from your carry-on bag and place them in a separated bag at the security checkpoint.

Does Frontier Charge For Carry On Bags?


Frontier carry-on baggage fee varies but the standard rate is about $30 if you check in early and pay for your carry-on on the airline website rather than the airport or the gate.

Please note that the gate fees are more expensive than the airport and the website.

So you will need to make sure that you respect Frontier Airlines carry on size and weight.

My Carry on is slightly big, What should I do?

Most airlines will apply an oversized baggage fee for any suitcase that is over the allowed size, However some passengers with soft sided bags may succeed to sneak in some extra size and weight on board.

If you are traveling with a very large suitcase you may consider checking in it, rather than taking the risk, checking your bag in the gate may cause a significant fee.

Frontier Luggage Connecting Flights

If you have a connecting flight provided by another airline, please review and respect the baggage transport rules set by this airline.
These rules may be different from Frontier airlines baggage rules. the airline recommends that you respect the most restrictive rules for the entirety of your trip.

The ideal Carry on bag for Frontier Flights

For the best experience not just on frontier flights or any other airline, you should be armed with a full sized carry on bag that fits the airline size and weight.

I highly recommend this Maximum Allowance Suitcases on Amazon, they will fit also most US Airlines carry on size.
