It's all possible with Frontier Airlines, provided that it does not dent the pocket too much; however, its strict baggage policy may catch someone by surprise. The biggest rule that a person needs to know is the Frontier personal item size limit as it is the only bag you can take on board without having to pay anything. In this blog, we could actually unpack all the details one needs to know about Frontier Airlines personal item size, personal bag size Frontier, Frontier checked bag size, and Frontier checked bag price so that one gets to have full knowledge on how better to avoid surprises through fees and travel smarter.

What Is the Frontier Personal Item Size Limit?

The airline allows each passenger to carry, free of charge, a personal item which fits under the seat directly in front of them. The dimensions of the Frontier personal item are strictly enforced: 14 inches high, 18 inches wide, and 8 inches deep (this measurement includes handles, wheels, and shoulder straps). This translates into a compact bag like a handbag, small backpack, briefcase, or laptop bag. 

To give you a clearer picture, the Frontier Airlines personal item size is about 33 liters or 2,016 cubic inches. A couple of examples of bags that would generally fit within the personal bag size Frontier includes:

• Small backpacks or daypacks
• Tote bags
• Laptop bags
• Diaper bags (great for parents traveling with infants)

Why It Matters: Frontier is known for being strict about the Frontier personal item size. Gate agents often use a bag sizer to check dimensions during boarding, and if your bag exceeds the personal bag size Frontier limit, you’ll be charged a hefty fee—sometimes up to $99 at the gate—to convert it to a carry-on. Measuring your bag at home and ensuring it fits within the Frontier Airlines personal item size is crucial to avoid surprises.

How Strict Is Frontier with Personal Item Size?

Frontier’s reputation for enforcing the Frontier personal item size is no joke. Gate agents are incentivized to check bags, with some reports suggesting they earn commissions for catching oversized items. This means you can’t rely on sneaking a slightly larger bag through. If your bag doesn’t fit in the sizer (which some claim is even smaller than the stated personal bag size Frontier), you’ll face additional charges.

Pro Tip: Choose a soft-sided bag that can be slightly compressed if needed. Rigid bags are harder to squeeze into the sizer, increasing your risk of fees. Always measure your bag, including any protruding handles or wheels, to ensure it meets the Frontier Airlines personal item size requirements.

Carry-On vs. Personal Item: What’s the Difference?

Unlike the free personal item, a carry-on bag on Frontier comes with a fee and has different size restrictions. A carry-on can be up to 24 inches high, 16 inches wide, and 10 inches deep (including handles, wheels, and straps) and must weigh no more than 35 pounds. These bags can be stored in the overhead bin or under the seat, but you’ll need to pay for them, with prices varying based on when and how you purchase the allowance.

• Cheapest Option: Add a carry-on during booking (starting around $59).
• Most Expensive: Pay at the gate (up to $99).

If you’re trying to save money, sticking to the Frontier personal item size and packing light is your best bet. However, if you need more space, consider the cost of a carry-on versus checking a bag.

Frontier Checked Bag Size and Price

For travelers needing more luggage, understanding Frontier checked bag size and Frontier checked bag price is equally important. Frontier allows checked bags up to 62 linear inches (length + width + depth, including handles, wheels, and straps) and 40 pounds. Here’s a breakdown:

• Frontier Checked Bag Size: Maximum 62 linear inches. Bags between 63 and 110 linear inches incur an additional $75 oversize fee per bag, per direction. Bags over 110 linear inches are not accepted.
• Frontier Checked Bag Price: Fees vary based on when you pay (booking, check-in, or at the airport) and the flight route. Typically, prices start at around $30 if purchased during booking but can climb to $75 or more at the airport. Overweight bags (41–50 pounds) cost an extra $50, while 51–100 pounds add $100 per bag, per direction.

Special Offer: As of March 2025, Frontier is running a promotion where passengers traveling between May 28 and August 18, 2025, can use the promo code "FREEBAG" to get one free checked bag when booking by March 24, 2025. This is a great way to save on Frontier checked bag price if your travel plans align.

Tips to Maximize Your Frontier Personal Item

Packing within the Frontier personal item size can be challenging, but with these tips, you can make the most of your free allowance:

1. Use Packing Cubes: Organize your clothes and compress them to save space.
2. Wear Bulky Items: Layer up with jackets or boots to free up bag space.
3. Choose a Lightweight Bag: A bag like the Nomad Lane Bento Bag or UUH Luggages is designed to meet Frontier Airlines personal item size while offering ample storage.
4. Roll Your Clothes: Rolling instead of folding maximizes space in your personal bag size Frontier.
5. Opt for Travel-Sized Toiletries: Stick to TSA’s 3-1-1 rule (3.4 oz containers in a 1-quart bag) to stay compliant.

Special Cases: Infants, Pets, and Medical Devices

Frontier offers some flexibility for specific situations:

• Infants: Passengers with infants can bring a diaper bag as a second free personal item, as long as it meets the Frontier personal item size (14 x 18 x 8 inches). Strollers and car seats can be checked at the gate for free.
• Pets: Pet carriers count as your personal item and must not exceed 18 x 14 x 8 inches. A $99 fee applies per direction for domestic flights.
• Medical Devices: Items like CPAP machines are considered medical devices and don’t count as a personal item, meaning they’re free to bring, provided they’re in a separate carry case.

How to Avoid Frontier Baggage Fees

To keep your trip budget-friendly, follow THESE strategies:

• Measure Your Bag: Double-check that your bag fits the Frontier personal item size before heading to the airport.
• Book Baggage Early: If you need a carry-on or checked bag, purchase it during booking to get the lowest Frontier checked bag price.
• Consider Bundles: Frontier’s Economy Bundle (available for travel between March 18 and August 18, 2025, if booked by March 24, 2025) includes a free carry-on, seat selection, and flight changes. The WORKS or PERKS bundles also include a carry-on and checked bag, which can save money if you need both.
• Use Elite Status or Credit Card Perks: Frontier Miles Elite Platinum or Diamond members get a free carry-on, and World Mastercard holders can earn two free checked bags.
• Test the Sizer Early: If possible, use Frontier’s bag sizer at an empty gate before boarding to confirm your personal bag size Frontier fits.
