Will be flying to Sydney late December on BA15/16 in First. I understand there is a 1.5hr stopover in Singapore, and just wondering pratically how this works? Do we offload or stay on the plane, is there really time to go to the lounge, and how long is there if have to de-plane & then re-load?

Bonus questions... is there an arrival lounge in Sydney open we will be able to use, and how can I tell if the plane will have Club Suite or not?

Cheers, LG
