I believe that QF is currently turning away non QF pax due to over crowding. Not sure how consistent this is and whether it’s only during certain times.
This doesn't surprise me - plenty of QF/OW elites travelling out of Singapore, especially towards the end of the working week and QF now have up to seven wide departures of their own in five hours in the evenings including the A380s to Sydney, Melbourne and then London later on. I imagine earlier in the week less of an issue and maybe around 8pm when the first "wave" has departed is OK
The hoardings are up for their F lounge so seems to be proceeding on schedule.
