Unfortunately, the nighttime flights dont work as India being India, a lot of my meetings are in the evening time with dinner etc. And who really wants to do back-to-back redeyes in Y? One is bad enough!SG operates two overnight flights BOM-SIN, SQ 423 and SQ 425, leaving 10:45pm and 11:40pm from BOM. I suggest the easiest option would be to use one of those to connect to your QF flight, with a daytime layover in SIN. You can sleep in a transit hotel in Singapore, which will be a replacement for the hotel night in BOM that you missed - this shouldn't really change your overall time spent in BOM or arrival date back in BNE.
