A dog died on an Air France flight from Amsterdam to Los Angeles, the airline confirmed to Business Insider in an email on Wednesday.
The animal was found in the plane’s cargo hold. Investigators are working to determine its cause of death.
“The dog’s owner has been notified and we express our condolences,” Air France’s statement reads. “In cooperation with local health authority in the US, the CDC, the dog was initially examined to ensure there was no immediately obvious public health threat.”
Air France says the dog was loaded correctly onto the plane, according to its pet policy.
Airlines have faced scrutiny over which pets they will transport and how they transport them.
Airlines have also faced questions over which animals passengers can classify as emotional-support animals. Delta Air Lines banned emotional-support animals from long flights in 2018, and United, American Airlines, and Alaska Airlines have also announced new policies around emotional-support animals in recent years.
