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

Just like the majority of ultra-low-cost 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 and it can be a backpack , small duffel bag or a small suitcase( subject for applicable fee)
  • 1 personal item without applicable fees ( free of charge )

Size and weight limits restrictions

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 depending on your ticket, 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, and Frontier is no exception.

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 some significant fees.
