DALLAS -- American Airlines is banning emotional-support animals in a move that will force most owners to pay extra if they want their pets to travel with them.
The airline said Tuesday that it will allow animals in the cabin free of charge only if they are trained service dogs. The change takes effect Monday, although passengers who already bought tickets can fly with their companion animals until Feb. 1.
The move follows a similar decision by Alaska Airlines and is likely to be copied by other carriers. The U.S. Transportation Department last month cleared the way for the crackdown against companion animals.
American Airlines said passengers with service dogs will need to complete a government form vouching for the dogs' health, training and temperament.
Other animals, including dogs not trained as service dogs, will be able to fly only in the cargo hold or a kennel that fits under a seat in the cabin. Either way, American Airlines will collect a pet fee ranging from $125 to several hundred dollars.
Jessica Tyler, the airline's president of cargo, said the rules will help passengers with service animals and protect employees on planes and in airports.
The number of passengers flying with companion animals grew rapidly in recent years, with some saying the animals helped them overcome anxiety and other issues. Passengers only needed a note from a health professional, and a cottage industry sprang up to provide those notes along with vests and other accoutrements for their animals.
Airlines and particularly flight attendants took a more critical view, saying passengers were exploiting a loophole in federal regulations to avoid pet fees. In a few cases, including some involving serious injuries, companion animals bit other passengers.
Last month, the Transportation Department settled the matter, siding mostly with the airlines. It said carriers were free to ban any animal other than dogs formally trained to help people with physical or psychological disabilities.
The department estimated that under the new rules, airlines will get $59.6 million a year in pet fees.
