interesting thread...so what about people who print two copies of a bording pass and instead of going to a BA lounge, go to another oneworld lounge based on Class of Travel...typically, i just show my bording pass and never another bit of ID to get in....i guess you could fly up front and a buddy in the back but both could be able to get into the lounge...
i agree, a few free drinks is not worth trying to scam my way in although i am sure the lure of the booze is too much to resist for some....
