A family is in mourning after their 10-month-old puppy was found dead following a flight from Houston to New York City.
On Monday, the french bulldog, named Kokito, was on board a United Airlines flight and was originally placed in TSA-compliant pet carrier that was designed to be small enough to fit underneath any of the seats.
However, a flight attendant allegedly forced the family - which included a mother and her two children - to place the animal and its carrier in an overhead bin for the entire four hour flight, as it was partly obstructing the aisle.
Those on the airplane reportedly heard Kokito bark throughout the flight, but were unaware it had passed away until they landed at LaGuardia Airport.
Passenger Maggie Gremminger, 30, said she wasn't the only one horrified over the incident, as the flight attendant became "frazzled" and became insistent she was unaware there was actually a dog in the carrier.
Following the incident, Gremminger posted on Twitter to express her grief: "I want to help this woman and her daughter. They lost their dog because of an @united flight attendant. My heart is broken."
