Delta flight diverted after passenger reportedly has 'diarrhea all the way through the airplane'

A Delta Airlines flight from Atlanta, Georgia to Barcelona, Spain was diverted back to its original airport after a passenger experienced an "onboard medical issue," which was reportedly a case of "diarrhea all the way through the plane."

The website FlightRadar24.com shows Delta Flight DL194 was about two hours into its eight-hour flight when it turned around over Virginia and headed back to Atlanta.

A user on X, formerly known as Twitter, who appears to devote his page to flight material shared audio recorded from the Airbus A350 that was broadcast on LiveATC.com.

"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 pilot added.
