Via New York Post A Delta flight from Atlanta to Barcelona was forced to turn around and make an emergency landing after a passenger “had diarrhea all the way through the plane.”

The Airbus A350 aircraft was two hours into a transatlantic flight from Georgia to Spain on Friday when the pilot asked to come back because of the fecal fiasco.

“This is a biohazard issue,” the pilot said to air traffic control recorded from LiveATC.com and shared on X.

“We’ve had a passenger who’s had diarrhea all the way through the airplane, so they want us to come back to Atlanta.”

The identity of the passenger remains a mystery, but the passengers and crew were transferred and Flight DL194 finally made it to Barcelona at 5:10 p.m. the next day — eight hours later than scheduled, according to Flightradar24.

It is not known if the passenger who had the diarrhea problem was aboard the plane when it touched down in Spain.

On a routine Delta flight bound for its destination, an unexpected and rather messy situation unfolded that required an emergency landing. Passengers and crew members were caught off guard when a passenger suddenly experienced a severe bout of diarrhea, causing a distressing scene inside the aircraft.

Given the urgency of the situation, the flight’s captain decided to divert the aircraft to the nearest airport where they could safely land. Passengers were informed of the situation and the change in flight plan, and they were asked to remain seated with their seatbelts fastened for the upcoming emergency landing.
