WestJet in-cabin pet policy — and the carriers that fit
WestJet allows small pets in the cabin in a carrier up to 16 × 10 × 8.5 in, soft-sided, stowed under the seat in front of you. The in-cabin fee is $50–$59 within Canada and the U.S. 1 of the 15 carriers we track clears that published limit.
The only one that clears it — the Sherpa Original Deluxe (Small) — matches WestJet's published limit exactly, with no measurable slack, so measure your own carrier before you fly. WestJet's 8.5" height ceiling sits mid-pack among the 17 airlines we track (shared with JetBlue, Southwest): Delta, American, United and Alaska allow more, while Air Canada allows only 8".

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

Common questions
What size pet carrier does WestJet allow in the cabin?
WestJet's recommended maximum in-cabin carrier is 16 × 10 × 8.5 in. It must fit fully under the seat in front of you. Source: the WestJet pet policy.
How much does WestJet charge for an in-cabin pet?
$50–$59 within Canada and the U.S.; $100–$118 outside Canada and the U.S. (pet kennel fee, as published on WestJet's fees page; applies each direction). Always confirm the current fee on the official WestJet pet page before you fly.
Which pet carriers fit WestJet?
1 of the 15 carriers we track clears WestJet's published 16 × 10 × 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. Full shortlist: /fits/westjet/.
Is WestJet's 16 × 10 × 8.5 in limit guaranteed on every aircraft?
No. WestJet states that space beneath the seat varies by aircraft type, and that depending on the aircraft you may be required to sit in a window seat because of limited space beneath non-window seats. Treat the published figure as a fleet-wide maximum, not a promise for your seat, and prefer a collapsible or flexible-height carrier.
How many pets can I bring in the cabin on WestJet?
One (1) pet per guest and per kennel in the cabin · the kennel counts as your personal item in your carry-on allowance. Species accepted: small dogs, cats, birds. Request space for your pet as soon as your booking is complete and at least 48 hours before departure — WestJet limits pets per flight and cannot guarantee space otherwise
