I'm sure you've spent a lot of time in both the QF and EK flagship lounges, as have I, but I'd rate the QF F SYD lounge as superior to its EK equivalent at Dubai.

Sure, it's not as expansive, although I personally don't count that against it - but the space, design, furnishings and fittings, spa and especially the dining for QF all trump those of EK, imho.

I know which lounge I'd rather be stuck in for three hours.
