More animals die on United flights than on any other carrier

More animals have died in the care of United Airlines than on any other U.S. carrier over the last three years — and it's not even close.

Eighteen animals died on United flights in 2017 alone, triple the amount of deaths on all other airlines combined, according to Department of Transportation data.

A total of nine animals lost their lives on United trips in 2016, according to the DOT records. Delta had the second most deaths with five.

United and Delta combined for 25 animal deaths in 2015, with 14 pets dying under United's watch.

In addition, pets on United flights suffered more injuries over the last three years than on any other airline.

Earlier this week a woman watched as her French bulldog was stuffed into the overhead compartment of her United flight, despite her pleas to remove her beloved pet from the enclosed space. Catalina Robledo's dog Kokito died during Monday's flight from Houston to New York.

A spokesperson for United told The Associated Press that it was not known why the stewardess did not put Kokito under Robledo's seat.

Robledo’s tickets were refunded along with the $200 fee charged for carrying a pet.
