Well first I tried with my Amex Centurion card, did nothing and was turned away after the lad looked at my Boarding pass being Qantas. Then went back and another lad was in charge and I said look can I just have a quick look as im interested in changing lounges in the future. Bingo, in I went and actually took video all the lounges so I could send back to family in Aus to let them know what the other lounges looked like.
Are you sure it wasn't just the SQ Biz Lounge?
