Not under the first definition of “sexual intercourse” in the Collegiate Dictionary. Under the second definition yes, but that definition would also include oral sex so is obviously not the one intended by the OP.
I’m on the side of including oral as well – as long as it is taken to its full conclusion, i.e. to orgasm by at least one of the parties. It’s not THAT easy, in the kind of tight-pitched packed-full flights I tend to take. Heck, it’s not that easy to get here on the ground! 
(OTOH, the SJU-CLE Saturday midday flight would be very propitious for covert activity, as it has a low load factor) Heck, I’d even extend to mutual manual (with or without devices) stimulation-to-orgasm. Otherwise it would be discriminatory to lesbian passengers and the airlines are not in any shape to ignore market degments 
From Merriam-Webster Online:
It covers all three. Just because oral has been discounted doesn’t mean anal is.
If you’re trying to be funny, ha ha.
If not, then Jesus Christ, your objection is a little, well, unnecessary.
I’m not a member yet… but I will be February 5, 2003. That’s the day my husband and I are flying to Las Vegas. My first plane ride ever… gotta make it memorable.
As for the OP… I think you should actually have intercourse in order to become a member. After all, how hard is it to give a guy a blow job in a small cramped bathroom? Ummmm, not very!

Smile when you say that!
I had hoped it would be obvious that any objection to the membership requirements of a fictional club would be so clearly unecessary that they would immediately be understood to be intended humorously, but I guess I was wrong.
The small shred of seriousness behind the humor would be that it is rather insulting to several groups and many individuals to insist that the only “real” sex is sex that involves a penis going into a vagina.
Which reminds me, dantheman, your revised defintion still excludes most lesbian sexual activities (and all lesbian sexual activities not involving special props). Why must lesbians be barred from membership in this elite club? As soon as I finish painting my picket signs I’m going to march right down to the offices of the Mile High Club and show them what’s what.
Damn The Man!
People have sex in Albuquerque?
EWWWWW!
Who would of thought, but:
I had always understood that one of you (at least) had to be piloting the aircraft. However, the web site says you can just be passengers in the lavatory.
But I’m one of the lucky ones! I hold a pilot’s license, and plan to add this little tidbit to my list of deeds done soon.
Envy me, all of you!
Don’t think so - can’t lesbians use fingers? The definition only says that the genitalia of at lesat one person must be used. 
Ah, but the anus is not a part of the genitalia, so the inclusion of anal sex still does the ladies no good.
However, if by the above you mean to say that you’re willing to include a round of good old-fashioned box buffing then our respective parties may be able to reach a compromise.
But I still think sex is sex is sex is sex, and anyone who insists upon saying that a particular sex act “doesn’t count” is just being silly. Sillier than me, even!
No, it is not cheating.
I’m not a member yet, but I will be one, eventually.
I’ll tell you what. This needs to be settled conclusively. I’m willing to fly with someone, somewhere. We can try all of the possibilities. In fact, we can even poll the flight crew otherwise. If they hold up signs of 5 or better, then it was an acceptable action; if not, back to the screwing board.
Who’s game?
"Just out of interest, how easy is it to actually do the deed? "
It depends. We were both pretty well looped on rum at the time, so the whole event took on a sort of weird acrobatic, fumbling, tone:
"Wait, I think I"ve almost got…
“No, no, wait, that’s not right…”
“Ow! Your elbows in my ribs…”
“Yeah, yeah, right ther…no, no, wait a minute…here let me sit down…”
KNOCK KNOCK KNOCK
“Oh fuck, what do we do now…oh yeah, RIGHT THERE!”
KNOCK KNOCK KNOCK
“Just a minute…”
In order to fullfill my responsibilities, I will volunteer. As I thought I had been a member for the last 27 years, and I find now that I have been sadly mistaken (vote is 9-5 for intercourse) - I must rectify the situation.
So, dantheman, how you doin’? 
[Checking out flights to Houston, and not to see Ringo…]
While I’m not a member of the club under either definition, I’d have to vote for oral sex not qualifying.
If it’s really important that such a ‘club’ not discriminate against gays, we say anal sex counts, as does penetration with strap-ons. This thread suggests the latter seems to have a following among at least some of the SDMB’s lesbians.
There. Are we being “inclusive” enough today?
I’ve had both oral and penetrative sex on a train. Is there a club for that?
Extra points if you’re on a United flight?
How do you do this without people knowing? Do you get funny looks when they see two people coming out of the bathroom with flushed looks on their faces?
I’m jealous.
“coming out of the bathroom with flushed looks”
What other kind comes from there?
