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. Already own a carrier? Enter its measurements below to check it against this limit. The in-cabin fee is $50–$59 within Canada and the U.S. 1 of the 15 carriers we track clears that published limit.

Last verified 2026-08-10 · 1 of 15 carriers we track fit the 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 58 airlines we track (shared with Cape, JetBlue, Southwest): Aegean, Air France, Air Transat and Alaska allow more, while EL AL Israel allows only 7".

📏 Short height: 8.5" is one of the shortest published height limits we track. Most standard 11"-tall carriers will not fit — look for collapsible or flexible-height models.

⚠️ WestJet states under-seat space varies by aircraft. 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. Here's how to confirm yours →

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.

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.

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
