An airline is investigating after a crew member recorded video of 2 passengers engaged in 'intimate acts'

• Two passengers engaged in "intimate acts" on a Swiss International flight from Bangkok to Zurich.
• A flight crew member took a video of the incident from a monitor in the cockpit.
• Swiss said the crew should have intervened immediately, and that it was investigating.

Airline crew members are under investigation after a video of two passengers on a Swiss International Air Lines flight emerged on social media.

The incident took place last Friday on a flight from Bangkok and Zurich, an airline spokesperson told Business Insider.

The spokesperson said two passengers were in the front galley of the Boeing 777 near the flight deck, where a camera is located that lets pilots carry out checks before opening the cockpit door.

From a screen on the flight deck, the couple were "observed engaging in intimate acts" while a crew member recorded them on a phone.

Footage of the couple then began circulating on WhatsApp and was obtained by the Swiss newspaper 20 Minuten, which first reported the story.

The airline said it expected the crew to intervene immediately and found it "intolerable" that the passengers were filmed and commented on instead. Disciplinary action against the crew members was being considered.

"Filming people without their clear consent and sharing these recordings is contrary to our guidelines and values," the Swiss spokesperson said.

"The behavior of the passengers in question was inappropriate — therefore, our employees should have acted in line with our protocols and intervened immediately," they added. "Why the crew did not act accordingly is the subject of the ongoing investigation."

Among other things, the airline plans to increase employee education and training on such topics to help avoid similar incidents in the future.
