The right travel kennel can keep your pet physically and emotionally comfortable throughout their journey. To make sure your pet has a comfortable flight, we have strict kennel requirements designed to keep your pet safe.
Failure to meet all kennel requirements will result in your animal not being able to travel on the designated flight. It will need to be rebooked for a later flight or day, which may result in additional expenses.
Find the Right Kennel Size
It is important you purchase the right size kennel for your animal. Place the animal parallel to the kennel in order to ensure the kennel is large enough.
- Each animal must have enough space to stand, turn about normally while standing, sit erect and to lie in a natural position.
- No part of your pet should be taller or longer than the kennel when standing outside the kennel.
- The length of the kennel should be a minimum of the length of the cat or dog, plus half of animal’s leg length.
- The tips of the animal’s ears must not touch the sides of the kennel.
For specific details on dimensions, please view IATA.
