Delta flight from Atlanta forced to return after passenger reportedly suffers diarrhea on plane. ATLANTA - A Delta pilot allegedly had to make an emergency landing back to the origin city when a passenger's loose bowels resulted in diarrhea all the way through the plane.

In September 2023, a Delta Air Lines flight from Atlanta to Barcelona made international headlines when it was forced to make an emergency U-turn over central Virginia due to a severe medical situation involving a passenger. The pilot communicated with air traffic control, explicitly stating that the aircraft had to return because of a "biohazard issue" after a passenger suffered from severe diarrhea that had spread "all the way through the airplane." The incident, which occurred on an Airbus A350, resulted in the flight returning to Hartsfield-Jackson Atlanta International Airport just two hours into its eight-hour journey. Upon landing, maintenance crews spent several hours deep-cleaning the aircraft and even replaced portions of the aisle carpet to ensure the plane was safe for subsequent use. Passengers were eventually moved to another aircraft and reached their destination in Spain after an eight-hour delay. The story went viral globally, highlighting the unusual and challenging operational decisions flight crews must make when health incidents create an environment that is no longer sanitary or safe for travelers and staff.
