It is very essential to keep in mind that the Air Canada Pet Policy is subject to change and may differ depending on the location and the specific flight. Pets are not allowed in the cabin on some flights, particularly those that are international. In order to fly in the cabin, a pet must be small enough to fit in a carrier that can fit under the seat in front of you.
