In ADL, when I flash my QFF card they sometimes ask to check which flight I'm on. When I asked why they do that, while in MEL,SYD,BNE they only look at the card, I was told that too many VA passengers are using Qantas Club so they must verify that I'm flying QF. Fair enough, extra 30 seconds won't kill me.
They did say that MEL,SYD,BNE all have separate terminals for VA and that's why they check only in ADL.
That's not true as QF has a lounge in the VA terminal in SYD and the lounge in BNE is not that far from VA as well.
I didn't argue but found it strange that they gave me such a lame excuse.
