Published in 2025 / Updated in 2026

JSX isn’t just pet-friendly; they’re pet-obsessed. Operating out of private terminals (FBOs), they allow you to skip the crowds and board just 20-30 minutes before takeoff.

Small Pets: The Under-Seat VIPs

If your pet is a lightweight, they travel for a flat fee and stay tucked right at your feet.

• Who’s Invited? Cats and small dogs.
• The Weight Limit: Small pets must weigh less than 30 lbs (including their carrier).
• The Cost: $100 USD per flight segment.
• Family Travel: You can bring one pet carrier per passenger. If you have two tiny pets that fit comfortably in one carrier (and are the same species), they can share the ticket!

Approved Carrier Sizes (Small Pets)

• Maximum Dimensions: 17″ L x 11″ W x 13″ H.
• The Comfort Rule: Your pet must be able to stand up and turn around. Since it’s a semi-private jet, the under-seat space is often more generous than a commercial “sardine can” flight.

Medium & Large Dogs: The “Buy-a-Seat” Hack

This is the game-changer. JSX is one of the only airlines that lets your large dog fly in the cabin without a crate.

• The Rule: If your dog is too big for a carrier but weighs 79 lbs or less, they can fly in the cabin!
• The Requirement: You must purchase the adjacent seat at the prevailing fare. Your dog doesn’t actually sit on the seat (safety first!), but they get to sprawl out on the floor directly in front of that extra seat.
• Booking: You can’t book this “Big Dog” option online. You must call JSX at (800) 435-9579 to secure your spot.

The Paperwork & Procedures

JSX keeps it professional so you don’t have to worry about a “ruff” arrival.

1. Pet Acceptance Form: Every pet owner must complete the JSX Pet Acceptance Form and present a printed copy at check-in.
2. Vaccinations: Up-to-date Rabies vaccination records are a must.
3. International (Mexico): If you’re heading to Cabo, you’ll need a health certificate, a USDA-endorsed permit, and for 2026, you must complete the CDC Dog Import Form if returning to the U.S.
4. Age: Dogs traveling internationally must be at least 6 months old.

🛑 Crucial Restrictions

• Cargo Policy: JSX has no cargo or shipping program. If your pet doesn’t fit the cabin rules, they can’t fly.
• Capacity: Only 5 pets are allowed per flight. With JSX’s popularity, these spots disappear faster than a dropped piece of bacon!
• Behavior: Pets must be leashed, well-behaved, and non-aggressive. If your pup is a “vocalist” (excessive barking), JSX may ask you to take the next flight.
• Species: It’s a Dogs and Cats Only club. Sorry, bunny and bird lovers!

💡 Expert Tips for a JSX Journey

Hydration Station: Most JSX lounges offer pet water bowls and treats before you board. It’s basically a spa day that happens to involve a jet.

Arrive Late (But Not Too Late): You only need to arrive at the private terminal 30 minutes before your flight. No long lines, no barking at strangers in the security queue!

The “Lap Infant” Exception: A very small dog (lap-infant size) may remain on your lap during the flight, though they must be in their carrier for takeoff and landing.
