Carrier size and weight

WestJet doesn't publish a weight limit for pets in the cabin. What matters is the carrier: your pet has to fit inside it, and it has to fit under the seat in front of you.

≈ 16.1 × 10 × 8.5 in (L × W × H)

  • Pets must be at least 8 weeks old.
  • The number of pets allowed on each flight depends on the aircraft.

Routes, breeds and other restrictions

Where pets can't fly

We haven't verified which routes, if any, don't accept pets on WestJet. Check the official page before you book.

Breeds

Short-nosed (brachycephalic) breeds are not accepted in cargo. For bookings made after July 4, 2023, short-nosed (brachycephalic) cats and dogs and their mixes can't travel in the baggage compartment and must go through WestJet Cargo.

Also good to know

  • If a guest with a severe cat allergy is on your flight, you may be moved toward the back of the plane to create a buffer zone.
  • Removing your pet from its kennel on board can get you banned from flying with a pet in the cabin on future WestJet flights.
