Habib Battah was traveling from Paris to Toronto on Air France on June 30, 2023, when he smelled what he thought smelled like manure coming from the footbed below his and his wife’s seats.

They were also traveling with their cats, who were in carriers below the seats. At first, Battah thought maybe the cats had an accident, so he looked at the cats, but they were fine.

However, and this is where the nightmare begins, Battah then noticed a wet stain underneath the cats’ carriers. He flagged a flight attendant, who gave him some wet wipes. But when he started cleaning, what got on the wipes was BLOOD RED. 

As it turned out, it was human blood. According to CNN, “The day before, on a Paris-Boston flight, a male passenger had suffered what Battah says the crew called a ‘hemorrhage.'” Although the passenger “survived,” the aircraft had not been cleaned. Worse, because the flight was full, Battah his wife, and the cats, were unable to move their seats.

It was later confirmed by Air France that the liquid was blood and feces.
