Options are getting limited for travelers looking to fly with unconventional animal companions. Southwest Airlines is the latest carrier to restrict the creatures allowed for emotional support on planes.
The new rules kick in Sept. 17 and mean Southwest passengers can no longer bring along emotional support animals that aren't dogs or cats, which must be on a leash or in a carrier, and limited to one per customer. Those traveling with an emotional support animal also need to bring along a current letter from a doctor or licensed mental health professional, Southwest said.
In addition, Southwest is restricting allowable trained service animals to dogs, cats and miniature horses. Any animals engaging in disruptive behavior like growling or urinating in the gate area may be denied boarding.
United's policy on comfort animals changed in March after an incident involving an emotional support peacock, which a passenger attempted to take on a cross-country flight in January. Upon toughening its requirements in the same month, Delta reported an 84 percent hike in animal incidents since 2016, including the mauling of a passenger by a 50-pound dog on a flight from Atlanta to San Diego last year.
U.S. airlines flew 751,000 emotional support animals last year, up 80 percent from 2016, according to the industry group Airlines for America.
