A couple flying to Mexico were caught shamelessly having sex in their seats as a husband and wife filmed the unexpected in-flight entertainment.
The clip shows a man and woman romping two rows behind their fellow passengers, who look wide-eyed with shock as they sneakily record the amorous pair.
At one point, the woman filming pans to show how small the plane is and that seemingly no other passengers have clocked on to the frisky business going on nearby.
The clip was uploaded to Twitter by Kiley Tully.
She said: "My mom and dad were just trying to have a peaceful trip to Mexico and they sent me this."
