Perfect. I'll be doing the SIN QR lounge before that and if I decide to leave home and get to the airport at 2pm, 6.5 hours before taking off on the 944 I might venture to terminal 4 to check out the CX lounge which I have yet to do so all these years, before the QR SIN lounge, then the BA arrivals lounge in LHR before I check into an airport hotel for 26 hours of layover time. Hitting up 4 lounges in 24 hours- never done this before!
