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 58 airlines we track (shared with Cape, Southwest, WestJet): Aegean, Air France, Air Transat and Alaska allow more, while EL AL Israel allows only 7".

How to confirm your actual under-seat space
JetBlue's number is a fleet-wide recommendation, not a promise 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 some window seats — they have less (or no) under-seat storage.
- Call JetBlue to confirm under-seat dimensions for that aircraft, or
- Choose a collapsible / flexible-height carrier that adapts to a tighter space.
