Oh and for the record, I've never successfully pulled this off. My girlfriend and I were flying to Nashville though and we'd talked for weeks about how we were totally gonna do it.
So we're on the flight, they've turned off the 'fasten seatbelts' sign, and we start discretely making out to get in the mood. When she's ready, I went back to the restrooms, went in and closed the door but didn't lock it. The plan was she'd follow me within a minute. I'm waiting in there, I see the door start to open, and then I hear a voice "EXCUSE ME, THERE'S SOMEONE IN THERE, YOU CAN'T BE GOING IN THERE."
Some asshole woman in the back row had totally busted her, so she hurried back to her seat, which we both agreed later in retrospect was pretty dumb. So I pretended to "finish up in the bathroom" and exited and as I walked past the lady, she said "I know what you two were going to do!" And I then employed my razor sharp quick wit to blast her with a reply: "You don't even... know what... my name is." We were both so confused by this that neither of us said anything further and I returned to my seat.
The post-script bummer is I realized when I sat down that I actually did need to take a leak but I sure as shit wasn't going back there again.
