A woman has been arrested after she allegedly performed oral sex on a male passenger on a Delta flight from Los Angeles to Detroit.
The 48-year-old woman and 28-year-old man, who were reported to have been strangers that met on the flight, were both issued citations after the woman allegedly performed oral sex on the man while they were in their seats on the plane, according to WDIV.
The pair were both connecting to separate flights -- the woman was heading to Nashville while the man was going to Miami.
"The act itself is inappropriate in a public space," said a passenger.
"There are children," said another. "There are families. There are seniors. These things should be respected."
"If people will go so far as to disrespect themselves and disrespect you, something should be done," said another passenger.
The investigation is reported to have been taken over by the FBI, who said the incident is still being investigated, and charges have not yet been decided. Charges could be issued as early as Oct. 31, FBI agents said.
Delta has yet to comment on the incident.
In August, a couple was caught engaging in sexual activity on a Southwest flight heading from Atlanta to Las Vegas, according to the New York Post. Police met the couple when they deplaned, but no arrests were made, and the investigation was reportedly dropped.
"Apparently, they just couldn't control themselves," said McCarran International Airport spokesman Michael Oram. "They were all over each other."
"Southwest does not condone this type of activity and we apologize to the other passengers onboard who were potentially exposed to this activity," the airline said in a statement about the incident.
A number of celebrities have previously also revealed that they were in the "mile high club," a term used for those who have had sex on an airplane, reports The Sun.
Reality television star Kris Jenner said she had an embarrassing experience when she had sex on a plane with her husband at the time, Bruce Jenner, who is now Caitlyn Jenner.
"We had sex in the bathroom and we came out and nobody said anything," recalled Kris. "At the end of the flight, the flight attendant got on the microphone, 'Congratulations, Mr. and Mrs. Jenner! You've just joined the mile high club. We're so proud of you, and we decided to give you a bottle of champagne! Yay!'"
"I could not squish down in my seat low enough," added Kris. "I was mortified."
In 2007, a stewardess for Qantas said that she had sex with actor Ralph Fiennes during a flight.
"I know some people will think it's disgusting," the airline employee said. "And I'm not proud of what I did -- it was inappropriate behavior. But I don't regret it."
"Ralph is gorgeous and the chemistry between us was amazing," she added. "What woman wouldn't want to make love with him?"
