According to air transat pet policy , customers can add their animal to the journey a few days before departure or when you board. If a passenger wants to reserve in advance, they must book a pet at least 72 hours beforehand. Contact the airline's authorities and depositing the required fee to the carrier will enable you to achieve this. If you decide you really want to bring your pet, you can do so by visiting the airport. Visit the check-in desk for this at least 90 minutes prior to the start of your flight. You can easily fly with your pet if you pay the pet travel expenses.
