American Airlines is no longer allowing emotional support pets on flights due to changing government rules.
The North Texas-based air carrier says the rules go into effect next week and travelers will soon have to fill out a government form two days before boarding planes.
New federal rules define service animals as a dog trained to help a disabled person.
An American spokesperson tells The Dallas Morning News pets weighing less than 20 pounds will still be allowed onto flights but have to be in carriers.
Alaska Airlines announced last week it would also no longer allow emotional support pets.
