Reports say that the woman was caught performing oral sex on the plane while the duo were still in their seats.
In case you missed it, a Delta flight that landed in Detroit on Sunday carried a 48-year-old woman and a 28-year-old man who failed miserably at joining the mile high club. Officials said the two were total strangers before boarding the plane.
The man was catching a connecting flight to Miami from Detroit while the woman was going on to Nashville, according to officials.
The feds said the two could be charged with anything from a misdemeanor to a felony.
One passenger on the flight reportedly told ClickOnDetroit.com, "There are children".
"We investigate crimes aboard aircraft, once the boarding door closes, regardless of severity", Federal Bureau of Investigation spokesman Ray Johnson told the Detroit Free Press.
WDIV reports that airport police issued them citations upon landing in Detroit, and the FBI is now investigating the incident because all suspected crimes that take place in the air are under federal jurisdiction. "There are seniors. These things should be respected", a passenger told ClickOnDetroit.
Delta has declined to comment on the incident.
Rather than fall in love, the two were caught committing a sexual act in their seats, and have since been issued citations.
