Traveling with Frontier Airlines in 2025? Before going to an airport both regular and new fliers should familiarize themselves with existing baggage policies. Knowledge of personal item dimensions and carry-on restrictions and checked-bag expense policies enables travelers to avoid delays as well as expenses and decrease their stress. You will find comprehensive information about Frontier Personal Item Size and the associated fees for carry-on bags according to this guide.

Frontier Airlines Personal Item Size Policy

Frontier Airlines provides low-cost flights together with expensive fees for passengers to bring their own items on board. All travelers are permitted to carry one free personal item with them. Frontier Airline passengers need to know the precise dimensions that qualify as personal items because it affects their travel experience.

In 2025, the Frontier Airlines Personal Item Size limit remains:

14 x 18 x 8 inches (35.5 x 45.7 x 20.3 cm)

This personal item must fit under the seat in front of you. Examples of acceptable personal items include:

• A small backpack
  
  

• A laptop bag
  
  

• A purse
  
  

• A diaper bag
  
  

If your personal item is larger than the allowed dimensions, Frontier may charge you a carry-on fee at the gate. This can cost more than pre-paying online, so it’s best to measure your bag before your trip.

What Happens If Your Bag Is Too Big?

A bag exceeding Personal Bag Size Frontier allows will automatically count as either a carry-on or checked bag. Frontier employees perform size checks through airport gate measuring bins for passenger bags. The rule states that bags which fail to match dimensions will incur additional fees that typically cost more when purchased at the airport than on the website.

Tip: Always measure your personal bag at home and compare it to Frontier’s limit of 14 x 18 x 8 inches.

Carry-On Bag Fees and Policy

Unlike some airlines, Frontier does not include a free carry-on with its basic fare. If you want to bring a carry-on bag, you’ll need to pay extra. A carry-on bag must not exceed:

24 x 16 x 10 inches (61 x 40.6 x 25.4 cm) including handles and wheels.

The price of a carry-on bag depends on:

• When you purchase (cheaper online, more expensive at the gate)
  
  

• Your route
  
  

• Whether you’re part of a bundle like “The WORKS” or “The PERKS”
  
  

Fees can range from $30 to over $60 depending on the above.

Frontier Checked Bag Size and Weight Limit

If you plan to check a bag, you need to follow the Frontier Checked Bag Size and weight guidelines. Each checked bag must not exceed:

• 62 linear inches (length + width + height)
  
  

• 40 pounds in weight
  
  

If your bag is larger or heavier, additional fees apply.

Overweight bags (41–50 lbs): $50 extra Oversized bags (63–80 inches): $75 extra

Frontier does not accept bags over 100 pounds or 110 linear inches.
