One time I was travelling out of YVR on BA. I was QF WP at the time, and I was travelling with a QF Gold. Would they allow us to take three guests into the lounge - no way !
So does Lindsay know you borrowed his identity at the time hmmm!
I've taken 2 guests to the SYD INT lounge and been admitted, as stated above, you just have to charm the agent and I really do have plenty to give - makes me sick sometimes just how "charming" I can be, yes, really but I do it in the knowledge that I can steady myself with a stiff drink at the end.
