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. 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: a collapsible or flexible-height model is the realistic option here. Air Transat's 10" height ceiling sits mid-pack among the 17 airlines we track: Delta, American, United and Frontier allow more, while Air Canada allows only 8".

How to confirm your actual under-seat space
Air Transat'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 Air Transat to confirm under-seat dimensions for that aircraft, or
- Choose a collapsible / flexible-height carrier that adapts to a tighter space.
