What was your strategy of getting the Mile High Club achievement? I've been thinking of going back and trying it again, so I need some good tips.

this is the one i used but i died just before i got to the Vip

Just memorize where to take cover, where to place you stun grenades and just spend 2 whole days doing it.

That's basically what i did and oh yeah... YOU HAVE TO GET A HEAD SHOT!

Good luck dude

use the guide pig gave you, or look at the one by Nexgenwalkthroughs.
best of luck

There are a lot of helpful videos on youtube.com that helped me get the achievement. Look up those.

oh god forget this achievement.  Talk about making you feel like a terrible player.

Youtube videos, and playing for an hour straight.

I don't even remember how many times I tried before giving up. It's way too hard.

My friend did it on veteran. He said he kept popping in and out of the sights to lock on to enemies.

I actually found the video on XBL's Insider Moves to be very helpful. Used the exact strategy they did to get the achievement last Friday night.

i played for 5 hours last night on it and i almost made it i keep running out of time get get to the final hallway and there's 1 second left and the plane blows up.

Go on youtube and follow what they do EXACTLY.

I just rushed through it as fast as I could and got it in about 15 minutes. It wasn't too bad, but something I would never want to try and get ever again.

I always run and knife the guy that comes out of the toilet, then I use flashbangs all the way!

very basically:

Knife the dude  that comes out of the toilets, throw a flash down the corridor, and mop up all the guys in the room directly in front of you while walking to get behind the seats on the right in the next room. Your guys will mop up any bad guys you left behind (hopefully >.<) The cabin will go ka-boom, throw a flash and take cover behind the seats in the middle, watching your right, theres sometimes a guy camping there. Dudes will come down the stairs, shoot them, run to the top while reloading. Throw a flash and shoot while taking cover, your guys will mop up most of them. Time is usually getting really tight for me here so I end up rushing through, you usually do have more time than you need though so chill out. Go through watching your right while throwing your last flash straight down the narrow corridor, run while shooting (youll probably have to get your pistol out at some point) and hopefully youll reach the hostage in time. Shoot the guy in the head as soon as the event starts. I got to this part 5 FUCKING TIMES before I shot him right.

Best Mile High Club strategy, right there. I tried over 100 times using various strategies, then I started using that one and got it after 4 tries."

I hate how for this mission you get a god damn silenced smg.  I also hate how stupid your teammates are.  I mean they should know we have to rush but no they don't and when they do it's at the staircase and they block your path.  That seriously happened once.
