What types of pets can be transported
The regulation defines a domestic animal as any companion animal that can live with people in a home environment. Wild animals and any species not considered a companion animal are excluded.
Guide and assistance dogs are not covered by this regulation, since they continue to be governed by their own regulations and retain the right to travel without additional restrictions.
How pets must travel
The animals must be transported in a closed carrier or crate, designed to guarantee safety, hygiene, and well-being. It may be placed on the passenger's lap, under the front seat, or in a seat next to the window, properly secured.
