United Airlines has settled with the owners of a French bulldog puppy that died after a flight attendant insisted that the carrier containing the dog be stowed in an overhead bin for a 3-hour flight.

The dog's death in March prompted animal rights groups to call for the flight attendant to be fired and United to change its rules for transporting pets. The furore even led to the introduction of federal legislation.

United Airlines declined to discuss the terms of the settlement but said "we are deeply sorry for this tragic accident."

New York attorney Evan Oshan, who represents the dog's owners, the Robledo family of Queens, said the airline and the family reached an "amicable settlement" but declined to discuss the terms.

"We hope the death of Kokito won't be in vain," he said, referring to the bulldog. "We hope all airlines will be moving in the direction of adopting the best safe transport policies."

The incident began when a flight attendant on a flight from Houston to New York ordered an animal carrier to be put in the overhead bin, saying it was too big to fit under the seat. The owners of the carrier said they told the flight attendant the carrier contained a dog but the airline said the flight attendant either didn't hear or understand that part of the exchange.
