Current QF F opening hours 14.30-23.00.

I had planned to visit QR also, but all the champagne makes my legs and head lazy 🙂.

Other useful SIN info if connecting: 3K Jetstar do print BP's for AY. They even printed my AY domestic leg. So whole another level of service compared to HEL. However 3K BP's doesn't show Oneworld status or number or travelclass. Needed to show my status and AY number in the app to the QF Dragon.
