Many people are turning to emotional support dogs to overcome their fear of flying and the anxiety that often accompanies air travel. There are important differences between service animals and emotional support dogs, so it is important to know what is and what is not allowed before you take to the skies. Emotional support dogs are a fairly new addition to air travel and not everyone is fully aware of the rules and regulations that govern these animals. By knowing what to expect from both the airline and TSA and security before you fly, you can avoid any unnecessary complications and stress.
