Show it at Sydney tower and they waive the $35 entrance fee...
the thrill wears off after awhile though...
Also good for any crew bar in SIN, HKG etc etc... discounted drinks, free food, yada yada yada...
Doesn't work for 'upgrades'on Virgin.... I practically had to twist the girl's arm to let me sit in a spare exit row seat... knowing full well they needed minimum 2 in each row... she came back and let me move
Get in quick and it's yours.... didn't flash the card for that though, it's just a bit sad. I do carry it when SLF-ing... just because you never know whose help you might need, fellow crew helping crew and all that jazz
