Understanding the value of your Frontier Airlines flight is understanding Frontier baggage fees.

All the additional fees that Frontier charges is the tradeoff for such low airfare. Frontier's baggage fees are some of the airline's strictest, though, so it's important to understand them thoroughly.

Your baggage allowance on Frontier varies depending on what fare you've purchased, when you purchase your bags, and what route of Frontier's you're flying, among other things.

In most cases, Frontier baggage fees look something like this chart for bags on flights from Minneapolis-St. Paul (MSP) to Denver (DEN) in September 2022. We tried a handful of other international and domestic routes on Frontier and found the same price chart when we searched, so this appears to be a good indication of what you can expect your Frontier costs to be.
 

Frontier baggage fees 

The fees Frontier charges at booking are the lowest you can find during the travel process. The next lowest baggage fees on Frontier are before check-in. Once you get the to airport, you can expect to pay as much as $20 more per bag on Frontier.

And Frontier checked bags are noticeably cheaper than carry-on bags are – especially when purchased during your flight booking.

As with every airline, every traveler gets one personal item for free on Frontier Airlines … at least so long as it fits underneath the seat in front of you.

 

Frontier Airlines Carry-On Baggage Policy

If your Frontier carry-on bag fits the airline's size parameters, you can bring it on board the plane with you and put it in the overhead bin.

Carry-on bags must be 35 pounds or less to qualify, and must be smaller than 24 inches tall, 16 inches wide, and 10 inches deep.
 

Frontier baggage fees 

It's worth noting that on Frontier, baggage fees are higher for carry-on bags than they are for checked bags. For most flights, the price difference is only $5 or so.

As with all Frontier baggage fees, the earlier in the process you book your bags, the cheaper they are. Carry-on bags booked at check-in will cost flyers $60 in most cases, but if you wait until you're at the airport, the bag will cost you $79 (or $89 if you have to check it at the boarding gate).

 

Free Bags on a Frontier Airlines Flight

No matter what fare you purchase, there's one Frontier bag that is always free: A personal item.

Personal items on Frontier Airlines are anything that can fit underneath the seat in front of you.
 

Frontier baggage fees 

According to Frontier, personal item bags can only be 14 inches tall, 18 inches wide, and 8 inches deep.

Make sure your bag is the correct size before heading to the airport, because paying for a carry-on or checked bag upon arrival at the airport could cost you up to $80.
 

Carry-On Baggage Fees and Specifications

Frontier carry-on bags must be no larger than 24 inches tall, 16 inches wide, and 10 inches deep or smaller in order to qualify for those specific baggage fees on Frontier.

If they are small enough to be considered carry-on bags, the bags typically cost around $60 when purchased during flight booking, but are slightly more expensive after that.

For instance, for a flight between Minneapolis (MSP) and Denver (DEN), Frontier charges $62 to add a carry-on pre-check-in, $64 to add one during check-in, $79 to add one at the airport or by calling customer service, and $89 to add one at the gate.

The single cheapest way to purchase a carry-on bag with Frontier is to purchase it online while booking your flight.
 

Traveling with Pets

Pets are allowed to travel on Frontier flights for a fee in the cabin, but cannot be checked as baggage. Pets on Frontier will cost travelers $99 each way and must be paid in advance during booking.

Travelers can still bring a personal item on board free of charge when traveling with a pet.

Pets must be “domesticated” according to Frontier, and all cats and dogs must be at least 8 weeks old. Frontier accepts dogs, cats, rabbits, guinea pigs, hamsters, or small household birds on its flights.

Large birds, rodents, beavers, ferrets, reptiles, amphibians, spiders, and insects are not allowed on any Frontier flight. Pets must remain in their carriers the entire duration of the flight, according to Frontier's rules.

Oh, and travelers with pets cannot sit in an exit row on Frontier flights.
 

flying with a carry-on pet 

The container itself can be a maximum of 18 inches long, 14 inches wide, and 8 inches tall. It's recommended that the case be soft-sided and the carrier must be large enough for the pet to stand, turn around, and lie down in a natural position.

If you're planning to travel abroad with your pet, make sure you go over the U.S. Department of Agriculture's guidelines about pet transport before you begin planning your journey. For instance, pet health certificates and vaccination proof are required in many countries where Frontier flies.

 

Frontier Airlines Checked Baggage Policy

Frontier Airlines baggage fees also apply to checked bags, but checking your luggage with Frontier is actually cheaper than carrying it on.

First, make sure your Frontier checked bags meet the size criteria. The size of your bag cannot exceed 62″ when you add the length, width, and depth of the bag together.
 

Frontier baggage fees 

Additionally, Frontier has a slightly stricter 40-pound weight threshold. Most major airlines allow bags up to 50 pounds, but not Frontier. Your baggage allowance on Frontier hinges on the size and weight of these bags, so double-check before leaving for the airport.
 

Checked Baggage Fees and Specifications

The best and easiest way to check for the latest, up-to-date Frontier baggage fees is to use the airline's “Bag Price Checker.”
 

Frontier baggage fees 

Just plug in your booked flights or your potential flights and the airline will give you a breakdown of what you can expect to pay.

As always with Frontier Airlines, the least expensive your bags will be is at booking.
 

Frontier baggage fees 

For most flights, your first checked bag costs just $55 if you purchase it at booking. Compare that to what it would cost if you try to check your bag at the airport, $79, and you're saving more than $20 by getting it done earlier.

Second checked bags on Frontier Airlines cost $60 at booking and as much as $89 at the airport.

For each additional bag, you can expect to pay a hefty sum. If you have the foresight to get it at booking, you'll pay $85, but at the airport, it's going to cost you almost $100. On Frontier, that's probably as much as the cost of your ticket!
 

Frontier Airlines Paid Special Items

Of course, there are always special items that travelers want to fly with, from guns, to hockey sticks, to trombones, and more. Frontier baggage fees for these items vary, too.

  • Frontier Airlines is a terrible airlines. Even when someone takes the time to understand the fees and bag charges the staff is just plain unprofessional. My flight was cancelled and no refund was given. They don’t give any refunds based on the type of ticket I bought. They denied service and a refund. The staff is just rude and don’t deserve to operate an airlines.

  • I recently flew from Detroit to las Vegas on Frontier Airlines. The flight there and back was good, but that’s all I can say about this airline. I was charged $67 and $64 for my carry on which I paid for before flight. I had a C-Pap machine which I had to cram into my small suitcase. At the Vegas Airport they pulled me aside and patted me down and took my shoes and suitcase to look at my C-Pap machine. I’m 70 years old, they couldn’t see the machine clear enough on the xray. My friend and I got to the airport 2 hours before the flight. By the time we got to the gate we were one of the last ones to board. I tried to call before we left Detroit to talk to someone about my machine. The number I called on the website was just a call center and very rude. The number I was given was just a recording, I never was able to talk to anyone. I don’t recommend this airline.

  • Frontier bag fees are a scam! We purchased tickets with them and paid a bag fee in advance, since it’s “cheaper” like that. They cancelled our flight and never refunded our bag fee! They kept our money for a service that was not even provided. The staff was very rude and unhelpful. We will not be flying with them anymore.
    If you add up the bag fee to the ticket price you can find much better options out there.

  • I will never fly Frontier again. It was a nightmare!! Cheap flights equals horrible customer service, cancelations without notice and the representatives that work for this horrible airline are rude and very unprofessional! I will be sure to let those i know who fly frequently to NEVER fly Frontier !!

  • Frontier is indeed a scam. And Priceline abets their thuggery. Buy a Frontier ticket thru Priceline and only after it is too late you learn that the ticket is a third of the fare. For good reasons, airlines are regulated. Write the FAA; write your Congressional Rep. this is bald thievery.
