Okay, wilderness crew, listen up. If your trail dog rides shotgun in the cabin the way Nala does, Frontier just made your day: dogs are accepted right there in the cabin with you, no cargo hold, no separation anxiety. That means your best trail buddy stays at your feet the whole flight. Grab that coffee, unfold the map, and let's sort out the details.

Frontier Airlines's pet policy splits into cabin and cargo. This page summarizes the weight limits, fees, brachycephalic-breed restrictions, and carrier specifications for both modes — sourced from the airline's official pet pages.

Frontier accepts dogs in the cabin only from a minimum of 8 weeks of age. Confirm the puppy has passed the 8-week mark before booking any cabin travel. Puppies younger than 8 weeks stay grounded. Check the birthdate against the departure date, and hold the booking until that 8-week threshold is cleared for the specific flight.

Frequently asked

How many pets can I bring on Frontier Airlines?
Frontier Airlines allows 1 in the cabin, per passenger. Each pet needs its own carrier.
How much does it cost to fly a pet on Frontier Airlines?
On flights within Metropolitan France, Frontier Airlines charges from 99 USD in the cabin, one way per pet. Longer routes cost more — price your exact itinerary.
What if my flight is delayed past my health certificate validity?
If the certificate window expires before you board, you'll need a re-issue. Build a 1-2 day buffer between the cert date and departure to absorb minor delays.
What happens if I forget a document?
At the destination airport: at best, an extended inspection while you produce backup; at worst, the pet is held in quarantine or returned to origin at your cost. Bring printed copies.
Frontier charges a cabin pet fee of 99 USD one way to bring a dog in the cabin. Budget 99 USD for each direction, so a round trip runs 198 USD. Add the fee when pricing the ticket, and pay it at the time of booking to secure the cabin spot for the dog.
So that's Frontier sorted: cabin dog, fee locked, chip checked. But every route has its own quirks, and your trip is not a generic one. Head over to Pawgo's plan-builder and pull a personalized plan for your exact departure, dates, and destination. Nala approves of anything that keeps the guesswork out of the airport.
