Airports join airlines in tightening the leash on animal travel
As had been widely reported, airlines have seen a sharp rise in the number of animals traveling on planes. Some are ticketed pets, but many are pets that have been flying for free thanks to loopholes in rules governing the transport of emotional or psychiatric support animals.
American Airlines reported a 40 percent increase in the number of service and emotional support animals on flights between 2016 and 2017. United Airlines cited a 75 percent increase year over year.
