Gary Leff, a travel blogger who first wrote about the change, recalled travelling years ago with a Yorkshire terrier.
“It was always frustrating that the dog counted as the carry-on even though I was paying the extra (pet) fee that was sometimes more than the ticket for me,” he said Friday.
Leff said he thinks American’s change will reduce the urge for travellers to falsely claim that their pet is a service animal that flies for free.
An American spokeswoman confirmed that the rules change took effect on Thursday.
“We made the change to provide a more convenient and comfortable experience to customers whose pets fly American,” she said.
In 2018 American Airlines was at the front of a crackdown on what it saw as abuse of rules on emotional support animals.
The airline prohibited flying with frogs, ferrets, hedgehogs and goats as therapy animals.
“Unfortunately, untrained animals can lead to safety issues for our team, our customers and working dogs onboard our aircraft,” said a spokesperson at the time.
