Pets in the Cabin

Frontier Airlines allows small pets (dogs, cats, rabbits, guinea pigs, hamsters and small household birds) to travel in the cabin on flights within the USA. Only dogs and cats are able to travel on international flights. It is your responsibility to make arrangements for complying with all applicable laws, customs and other governmental regulations, requirements or restrictions of the country, state or territory to which the animal is being transported. Your pet's carrier must be able to fit underneath the seat in front of you. The pet fee on Frontier Airlines is a one-way, directional charge of $99

Pets in Checked Baggage

Unfortunately, Frontier Airlines no longer accepts pets as checked baggage or as cargo.

Carrier Guidelines

For pets traveling in the cabin, carriers on Airbus A318 / A319 / A320 should not exceed 24" x 15. 5" x 9.5" (61 cm x 40 cm x 24 cm); and on Embraer E190, the carrier dimensions shouldn't exceed 18" x 13.5" x 10" (45 cm x 24 cm x 25 cm). Carriers must be large enough for animals to stand, turn around, and lie down in a natural position. Frontier recommend that you use a soft-sided carrier.

Other Restrictions

Frontier will no longer accept new bookings for passengers wishing to travel with an emotional support animal.

    Changed the rules after I bought ticket

    They changed the rules about ESA's after I bought my ticket and expected me to look at the website to know about the change in rules.

    Great for bringing guinea pigs!

    Frontier was the only airline we found that would allow us to bring our guinea pig in the cabin (not sure why others do not allow them but they do not seem to). TSA, staff for boarding and flight attendants were all nice, curious and friendly. We will use them again!

    Would do so again on a direct flight

    I brought my twelve-pound Chihuahua on a direct flight in April 2018, and all went well in spite of a forty minute delay in the airport and arriving early at the airport on the return portion. In the airport, I waited with her near the Pet Relief Area. While she walked through the airport, I put her inside the carrier during the flight in the Airbus as well as in the rental car shuttle. The fit of the soft-sided carrier under the seat (mostly) left something to be desired, so on my next flight with her, I have purchased the premium stretch seat. I don't know whether or not the steward would have offered to place (safely) the carrier elsewhere in the cabin, though one inquired on the return whether it would fit under the seat. Of course, it did do so going.

    Great Airline

    So far, I've had pretty good experiences with Frontier. Although I have had one issue where my flight was rescheduled that made me have a delay, but that was fine because they did compensate me for it and still allowed me to fly. I recently had to move across country and I flew with Frontier. I have two small emotional support cats that I only keep at home, but I didn't want to take them on a 14 hour drive, frontier happily allowed me to bring them (although they both have to fit in the same crate.) which isn't that hard. Thankfully.,

    Super Friendly and understanding

    I flew with my Emotional Support dog (mini-schnauzer) for the first time, and I was incredibly nervous about the carrier situation since their under seat area is a little smaller than other airlines. However, the flight attendant told me I could keep him out on my lap. Every flight attendant that came by was incredibly kind and friendly toward me and Shaker, both on the way there and back. It was such a relief to be able to have him on my lap the entire trip! I'm hopeful that my next trip with Frontier will be equally as positive!

    (side note: This was just luck, but the couple next to me was also incredibly understanding of my having him out, and even offered to hold him when I went to the bathroom so he wouldn't have to go back in the carrier!)

    Emotional Support Dogs

    Unfortunately, I did not have a positive experience flying Frontier for the first time with my emotional support dog (a small pug). The carrier couldn't be pushed under the seat all the way (never the case with other airlines) and the flight attendant kept insisting that it be pushed in. She even manually tried to shift it around herself and she was NOT gentle about it. Afterwards, in a condescending tone, she told me that having my carrier/dog there was "illegal" which I did not appreciate considering he was my emotional support animal.

    I plan to pick up a puppy in Seattle and bring him back to Denver. The only price shown is $150 on the web which suggests a round trip with a pet. Tried to call and got in "hold", "what do you want recording", finally gave up and went United.

    Pup with Pearls

    I was looking at flights to Denver and Frontier boast "low fares done right" when I went to book it was very easy to add a pet to my ticket, and very reasonable at $75 each way. However with all the other add ons like carry-ons I began to wonder about extra fees. I decided to call and after a 30 minute wait time I got someone that said that I would have to pay again for my pet as a carry on because a pet doesn't count as a personal item like on other airlines. So I don't see how this is "low fares done right if I have to pay twice to fly.

    Inconsiderate Flight Attendants

    We have flown many times with our small Jack Russell with various airlines and the flight attendants are usually very accommodating. Our most recent trip with Frontier left us overwhelmed and unhappy. As soon as arriving on the plane the flight attendant made a point to yell to us from the middle of the plane that the dog must remain zipped into the case the entire flight. Other airlines have allowed us to unzip the top of the case while in flight (pets must be zippered in and under the seat during take off and landing). And this allows the air to circulate and for us to comfort and give refreshment to a stressed animal. They were very unkind when we tried to explain.

    I travelled with my 19 lb shih tsu mix from Nashville to Spokane and back a few weeks later. Not only did they allow my big soft sided carrier, they also gate checked my dogs stroller. I put her in the stroller in the airport on the layover so she can stand up and move around. They were nice at the counter and at the gate they didnt even notice I had a dog. My dog is quiet-never barks. Most everyone around me didnt even realize I had a dog.

    And for anyone who complains about allergies, I have had allergic reactions to people's stinky perfume, B.O., cigarette stink, etc. My dog is groomed and way better smelling than a lot of people!

    If could only get someone on the phone

    I need to send my animals by plane, which costs a LOT of money. But I can't even get a real person on the phone. So i can't even make a resrvation if I wanted to. Very bad first impression.

    Bringing the kids

    Frontier does allow 1 pet in cabin per passenger and 2 additional if needed as cargo. They are one of the few airlines that allow you to fly with your bully breed as long as the weather permits. Many others put full embargo's during the summer. I flew my last bulldog with them twice and he was taken care of. One employee heard him yelping when he saw me at a transfer and offered to take him out to go to the restroom. I'm booked to fly them again with my dog and cats and hope to have another great experience.

    Frontier has never not allowed Service Dogs on board the aircraft. We evel allow "emotional Support" animals to travel on baord the aircraft with the proper documentation. As for other dogs, you can purchase a seat on frontier for a fee or place the animal in cargo for a fee. As with all airlines, pets in cargo are subject to weather and weight restrictions for that particular flight. I have a dog that travels with me on Frontier in the cabin all the time.

    Service Dogs

    XXXXXXXX to be accompanied by his Service Dog in the cabin of the aircraft, in accordance with the Air Carrier Access Act (49 U.S.C. 41705 and 14 C.F.R. 382). There are some additional guidlines that must be met but if you meet the legal definition of being disabled then Frontier Airlines CANNOT RESTRICT YOU FROM TAKING THE SERVICE DOG INTO THE CABIN!

    Dogs On Frontier Airlines

    Article is not totally correct. Please check ADA guidelines as a Service Dog is allowed inside the cabin with the handler and they are not permitted to charge any additional fees for the Service Dog.

    Great For Pets!!!!

    I have a mini schnauzer, he is not small enough to fit in the cabin. We have traveled 4 trips with my dog and Frontier. Every time it seems that they really care. One instance, the lady at the gate double-checked to make sure my dog had enough water by going outside and giving him water personally through his cage before they put him on the plane! The pilot then assured me that "Banjo" was fine and hanging out with Jay the parrot! ;) This was really the most amazing thing ever!!
