When traveling with your pet, you have two options—in cabin or cargo hold. Pets who travel in cabin are in the custody of their pet parents, while pets traveling in the cargo hold are in the airline’s custody. Each airline has its pet policies, but, in general, only small dogs and cats can travel with their pet parents in cabin. If you’re wondering what size dog can fly in cabin, the typical rule is that the pet will need to remain in a soft-sided container the entire flight—and this container needs to fit underneath the seat directly in front of you. Unfortunately, your dog cannot sit in your lap on the plane. Larger pets will travel in the cargo hold area, and each airline has its own specific policies. However, some airlines, such as Southwest, JetBlue, and Spirit, will not transport pets in the cargo hold. Certain brachycephalic breeds (including dogs such as Pugs and Boxers and cats such as Persians and Himalayans) should not fly in the cargo hold, because they are at higher risk of breathing issues. According to Nelva J. Bryant, DVM, MPH, an airline industry veterinarian and pet travel expert based in Atlanta, Georgia, if your pet is well-prepared to travel and has been medically cleared by their veterinarian, it is safe to fly in the cargo hold.,Whether you’re gearing up for a big move or planning a holiday vacation with your furry best friend, flying with pets requires careful planning and preparation. From navigating airline policies to ensuring your pet’s comfort during the journey, there’s a lot to remember. Here, we’re covering everything you need to know to make your pet’s travel experience as smooth and stress-free as possible.
