JetBlue in-cabin pet policy — and the carriers that fit
JetBlue allows small pets in the cabin in a carrier up to 17 × 12.5 × 8.5 in, soft-sided, stowed under the seat in front of you. Already own a carrier? Enter its measurements below to check it against this limit. The in-cabin fee is $150 each way (or TrueBlue points). 1 of the 15 carriers we track clears that published limit.
The only one that clears it — the Sherpa Original Deluxe (Small) — matches JetBlue's published limit exactly, with no measurable slack, so measure your own carrier before you fly. JetBlue's 8.5" height ceiling sits mid-pack among the 77 airlines we track (shared with Cape, WestJet): Aegean, Air Europa, Air France and Air Transat allow more, while EL AL Israel allows only 7".
Will your carrier fit JetBlue?
Measure the outside of your carrier (bulges included) and enter it below. The check uses JetBlue’s published 17 × 12.5 × 8.5 in limit — height is checked strictly, the footprint may rotate.

This table ranks by JetBlue’s size limit — not by your pet. The weight under each carrier is what that size is rated to hold. A bag can clear the airline and still be the wrong size for the animal, which is the most common reason one goes back — measure your pet first →

How to confirm your actual under-seat space
JetBlue's number is its published maximum, not a guarantee for your exact seat. Before you buy or fly:
- Check which aircraft operates your flight (in your booking or on a seat-map site).
- Avoid bulkhead and exit rows — bulkheads have no under-seat storage and most airlines ban pets there — and check this airline's seat rules above.
- Call JetBlue to confirm under-seat dimensions for that aircraft, or
- Choose a collapsible / flexible-height carrier that adapts to a tighter space.

How much does JetBlue charge for an in-cabin pet?
$150 each way (or TrueBlue points). Always confirm the current fee on the official JetBlue pet page before you fly.
Which pet carriers fit JetBlue?
1 of the 15 carriers we track clears JetBlue's published 17 × 12.5 × 8.5 in. The roomiest is the Sherpa Original Deluxe (Small), and even that one matches the limit exactly rather than clearing it, so measure before you fly. The heaviest pet any carrier that clears JetBlue is rated for is 8 lb. Full shortlist: /fits/jetblue/.
Does JetBlue require a soft-sided pet carrier?
Yes — JetBlue requires a soft-sided carrier in the cabin. Height is what rules carriers out: JetBlue publishes 8.5", against 13" at the most generous airline we track.
How many pets can I bring in the cabin on JetBlue?
2 per traveler (each in its own carrier; 2nd needs a 2nd seat + fee) · 6 per flight. Species accepted: small dogs, cats. Add in the Extras section at jetblue.com or the app
