Airline passengers have to deal with a lot these days; getting bumped from flights and losing luggage on top of the general anxiety that nervous passengers always feel. At the Cincinnati/Northern Kentucky International Airport, miniature horses deliver a calming force two times a month. Denver and Ruby are two of the 34 therapy horses brought in from a local farm. They can usually be found in the ticket counter area interacting with travelers. More than 30 airports across the country now have therapy dogs. San Francisco has a therapy pig. San Jose, California, began a dog program after the terrorist attacks of Sept. 11. Since its beginning, the program has now grown and has 21 therapy dogs and a therapy cat. The animals don’t get startled. They have had hundreds of hours of airport training so they are used to having luggage and people crowding around them. These professional animals are probably better at finding their way in the airports than the most frequent of travelers. The passengers often say that seeing animals makes them feel much better and helps them to calm down before a flight. This little bit of support can sometimes make a big difference. Some passengers enjoy the animals so much that they call the airport to schedule flights around their visits. Visits to nursing homes and schools are also a regular part of the horses’ schedule. Their owner is already working on a new idea for a therapy animal—donkeys.
