Flying with Your Pet on JetBlue: Everything You Need to Know
OK hear me out — I've flown Nala, my 22kg Australian Shepherd, on basically every major US carrier, and JetBlue's pet policy is genuinely one of the most straightforward out there. Whether you're bringing your furry friend in the cabin or checking them below, this guide breaks down exactly what JetBlue requires, what it costs, and how to nail the logistics so you and your pet actually enjoy the journey.
I'm not gonna sugarcoat it: flying with pets requires serious prep. But once you know the rules, it's totally doable. Let's walk through this together.
Can Your Pet Fly in the Cabin with You?
Yes — dogs and cats can travel in JetBlue's cabin. This is the gold standard for pet travel because your furry friend stays with you the whole flight. No cargo hold stress, no temperature worries, no separation anxiety. Trust me on this one: if your pet qualifies for cabin travel, that's your move.
Here's the catch: your pet has to be small enough to fit under the seat in front of you in a soft-sided carrier. This isn't a suggestion — it's a hard requirement.
Cabin Carrier Dimensions & Weight Limits
JetBlue's cabin pet carrier must fit these specs:
- Length: 43 cm (17 inches) maximum
- Width: 32 cm (12.5 inches) maximum
- Height: 22 cm (8.5 inches) maximum
- Combined weight (pet + carrier): 9 kg (20 lbs) maximum
The carrier must be soft-sided — hard-sided crates won't fit under the seat. Look for collapsible carriers with mesh panels for ventilation. I use a Sherpa bag for Nala when she was smaller, and it's held up through dozens of flights.
Real talk: if your dog or cat weighs more than 9kg total with the carrier, you'll need to explore checked baggage or cargo options instead. Nala's at 22kg now, so cabin travel isn't an option for her anymore — but when she was a puppy, we made it work.
Cabin Pet Fee
$125 USD per pet, one way. So a round trip is $250. This is a flat fee regardless of flight length, which is actually pretty reasonable compared to other carriers.
Cabin Booking Requirements
You must book your pet at least 24 hours in advance — you cannot show up at the airport with a pet and expect to bring them aboard. JetBlue limits the number of pets per flight, so early booking is essential. Call or book online as soon as you have your flight details locked in.
Only one pet carrier per passenger is allowed in the cabin. So if you're traveling solo with two small dogs, they'd need to share one carrier (which, realistically, only works for very small pets).
Health Certificate & Documentation
This is non-negotiable: you need a vet-issued health certificate dated within 10 days of your departure. Get it as close to your travel date as possible — don't wait until the last minute. Your vet will examine your pet and issue the certificate, which you'll present at check-in.
Even if JetBlue's website doesn't explicitly mention it, the airport staff will ask for it. I've seen people denied boarding without one. Don't be that person.
Breed Restrictions: Brachycephalic Breeds Are Banned
JetBlue does not allow brachycephalic (snub-nosed) breeds in the cabin due to respiratory risks during flight. This is an industry-wide safety standard, not just JetBlue being strict.
Restricted breeds include:
- Bulldogs (all types: English, French, American)
- Pugs (all types)
- Boston Terriers
- Boxers
- Shih Tzus
- Pekingese
- Chow Chows
- Japanese Chin
- Lhasa Apso
- Shar Pei
- Pit Bulls and related breeds (American Pit Bull Terrier, Staffordshire Bull Terrier, American Staffordshire Terrier, American Bully)
- Mastiffs (all types)
- Cane Corso
- Dogue de Bordeaux
- Presa Canario
If your breed is on this list, you might still be able to travel via checked baggage or cargo, but cabin travel is off the table. Check with JetBlue directly to confirm your specific breed.
Age Requirements
Your pet must be at least 8 weeks old and fully weaned to travel in the cabin. Younger puppies and kittens aren't ready for the stress of air travel anyway.
What You Cannot Do
Do not sedate your pet. IATA regulations (which JetBlue follows) strictly prohibit sedation during air travel. A sedated animal can't maintain balance or respond to emergencies. Even if your vet suggests it, don't do it unless both your vet and JetBlue explicitly approve it in writing — which they almost certainly won't.
Also, visibly pregnant animals are not accepted for cabin travel due to health risks. If your pet is pregnant, contact JetBlue before booking.
Checked Baggage & Cargo Options
If your pet is too large for the cabin, JetBlue allows travel via checked baggage or cargo. Here's what changes:
- Carrier type: Hard-sided, IATA-compliant crates only (soft-sided won't work)
- Water bowl: Must have an attached water bowl or trough that can be filled from outside
- Absorbent liner: Required inside the carrier
- Live Animal labels: Required on at least three sides with orientation arrows
- Ventilation: Openings on at least three sides per IATA standards
- Minimum age: 10 weeks (older than cabin travel)
- Temperature restrictions: Not allowed if tarmac temps exceed 29.4°C (85°F) or drop below -6.7°C (20°F) — though vet acclimation certificates may allow travel in colder conditions
- Advance booking: Required; you cannot show up with a pet
- Health certificate: Still required, dated within 10 days
- Brachycephalic breeds: Still banned

What You Need to Do: Pre-Flight Checklist
- Schedule a vet appointment — Get your health certificate issued within 10 days of departure. Don't wait.
- Book your pet at least 24 hours ahead — Call JetBlue or book online. Mention your pet's weight and breed to confirm they qualify.
- Get the right carrier — Soft-sided for cabin, hard-sided IATA-compliant for checked/cargo. Measure it against JetBlue's specs.
- Add absorbent liners — Line the carrier with pee pads or absorbent mats. Accidents happen.
- Confirm breed restrictions — If your pet is a brachycephalic breed, confirm with JetBlue whether cabin travel is possible.
- Practice carrier time — Get your pet comfortable in the carrier weeks before travel. Take short trips in the car first.
- Exercise before the flight — A tired pet is a calm pet. Walk or play with your dog before heading to the airport.
- Bring water and food — Pack collapsible bowls and your pet's regular food. Bring enough for the flight plus delays.
- Arrive early — Give yourself extra time at the airport for pet check-in procedures.
- Keep documents handy — Health certificate, booking confirmation, and ID should be easily accessible.
Pro Tips from My Experience with Nala
When Nala was small enough for cabin travel, I learned a few things the hard way. First, book a direct flight if possible — connections mean more time in carriers and more stress. Second, choose an aisle seat so you can discreetly check on your pet without climbing over seatmates. Third, bring a small blanket or familiar toy inside the carrier — it helps with anxiety.
For larger dogs like Nala is now, I've had to use checked baggage on a few flights. The hardest part isn't the logistics — it's the emotional piece of not having your pup with you. But JetBlue's process is solid, and I've never had an issue.
One more thing: arrive at the airport with time to spare. Pet check-in takes longer than regular baggage, and you don't want to be rushed.
