Yes. All US domestic Airlines allow ESA owners to travel with their Emotional Support Animals. We recommend that you contact your airline prior to check-in to let them know that you are traveling with an Emotional Support Animal so that they may provide appropriate accommodations. Similarly, for Travelling (by air), you wouldn’t have to pay any additional deposits, costs, or fees to the airline for taking your pet on board with you since the letter is good for a whole year (12 months) so most of our average ESA LETTER HOLDERS  save around $450-$600 in additional fares for traveling with their pet by air, all around the year!
