In the United States, every Service Dog handler enjoys the right to travel with their Service Dog. However, finding straightforward information about airline policies and requirements, international laws, TSA regulations, security checkpoints, and other commonly encountered situations isn't easy!

Terminology note: U.S. Federal law includes miniature horses in the list of allowable Assistance Animal species.

However, that's far from universal -- airline working dog policies range from nonexistent to clearly defined with everything in between! All handlers should confirm their airline's Working K9 or Service Dog travel policy several days prior to flying. Airlines accept Service Dogs in Training (SDiTs) at their own discretion. Service Dnimals in Training are not covered by the Air Carrier Access Act (ACAA) and therefore have no legal rights to fly under any Service Animal policy.
