Air Transat in-cabin pet policy — and the carriers that fit
Air Transat allows small pets in the cabin in a carrier up to 17 × 9.5 × 10 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 $50 within Canada or to the USA · $100 to Europe, Africa, or South destinations (Caribbean, Mexico, Peru, etc.) — per pet, per flight segment, paid up to 24h before departure. 0 of the 15 carriers we track clear that published limit.
That means no carrier on our list clears it outright — the closest is the Sherpa Original Deluxe (Small) (squeezes — 0.5" over), with 1 other in the same range. Measure yours and expect an agent to check it. Air Transat's 10" height ceiling sits mid-pack among the 77 airlines we track (shared with Avianca, Contour, Southwest): Air Europa, Allegiant, American and American Eagle (regional, incl. Republic Airways) allow more, while EL AL Israel allows only 7".
Will your carrier fit Air Transat?
Measure the outside of your carrier (bulges included) and enter it below. The check uses Air Transat’s published 17 × 9.5 × 10 in limit — height is checked strictly, the footprint may rotate.

This table ranks by Air Transat’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
Air Transat'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 Air Transat to confirm under-seat dimensions for that aircraft, or
- Choose a collapsible / flexible-height carrier that adapts to a tighter space.
