I hate flying in a passenger plane too, but my reaction is to be as alert and straight as possible the entire flight - just in case I need to save the plane by flapping my arms or something. The thought of being in any way impaired during a flight bugs me more than the flight does.
The weird thing is that flying only bothers me on a big plane. Put me in a Cessna or a helicopter and I’m fine.
And no, the Mile High Club (Airborne) has eluded me so far.
The rotary mile high club is considerably more exclusive - because helicopters do not routinely have any good reason to fly a mile above ground level, because there’s usually little privacy from the crew, and because if you’re flying it yourself it generally requires a lot more attention than fixed wing.
Again, as stated by the OP - sitting in the hangar in Denver doesn’t count. It’s a mile above ground level, not sea level.
So this would be an impressive achievement - any members on here? I’d have to guess most likely somebody in a large military transport heli, if anything?
Whatever anyone may say, you sure do get a lot of privacy…
I have fooled around while we were sharing a blanket but never gone all the way.
We did it in the refueling seat of a KC-135 right after fueling up a B-52D. A bunch of us were being transported to Guam, and she wanted to know if I’d like to watch the procedure. The ships docked.
The ships undocked.
We followed suit.
I have, a couple of times; even made a video that I loaded to Vimeo of one of them.
Sadly, in a balloon, the mile high club is just higher than 5280’ & does not include the downward travel of zippers.
Yes both on a domestic flight and an international flight.
That’s not what I read in the Penthouse letter you wrote. 
No but I am a member of the Force Ten club - on a ship in a near hurricane in the North Atlantic.
Sigh… I figured any username-post combos for me would involve a boat trailer or something. Didn’t see that one coming. 
But yes, there were two of us. In one instance, (the future) mizpullin fretted about closing the curtains on the passenger windows. I assured her we were unlikely to be observed.
No, generally I’m too busy flying the plane to get it on with my spouse.
I had to change a monster blow-out poopy diaper in the plane’s tiny little lavatory a week ago - is there a Club for that?
That would be the Pile High Club.
Well, I don’t know… What do you have in mind?
Hey-O!
Traveling messes with my stomach, too. :eek:
12,000 feet - Trail Camp on the Mt. Whitney Trail in the Sierra Nevada range. Also below sea level in nearby Death Valley. (-190 feet)
Flying boom or drogue and probe? 
Boom.
Never mind Denver. People don’t realize Albuquerque is on a slope and 4900-6700 feet, depending on where in the city you are. Santa Fe is 7200 feet. I used to live in Albuquerque, so I’m a member in that sense.
