I was in the Sin QF lounge this week and on arrival and for the first two hours it was jammed. However once QF1 and some others departed early evening it was quiet. As a platinum, there is a line of seats pre allocated and a little more service offered but there is really no difference and frankly the whole place has a Qantas Pub not Club atmosphere. Dining area feels like a cafeteria and the whole place is no different to the business lounge in Sydney or Melbourne which is not saying much. I wouldn't be making plans to get to my flight early based on this experience regardless of my status or class of travel. Indeed as a result of QF's move back to Singapore, I might even re.evaluate my Asian stopovers away from Sin.
