Larger animals may need to fly in the cargo area, which can be very stressful for both your pet and for you. This option should only be considered if absolutely necessary. In this case, it may be better to leave your pet with a trusted pet sitter.
For Cats and Small Dogs, travelling in the cabin with their owners is an option as long as your pet is in an airline approved carriers for carry-on travel. They are usually made of a soft, durable material which makes it easy to fit it underneath the seat in front of you on the plane. Always label the carrier with your name and contact information as well as the number for your veterinarian. Another good idea is to include any special instructions if your pet takes any sort of medications or requires any specific care.
Once you are on the plane, you may be allowed to open the carrier to check on your pet and give them some treats or water, or to offer a comforting touch! This is by far the best way to ensure their safety and comfort, as they will be with you for the entire trip.
