Only speculation of course, but perhaps 16/34 closure looks like a reasonable possibility with an earlier arrival time than expected;

And 27 would not be an option with the taxiway closures even though given those conditions according to the LPA a MLW up to a little more than 400 t would be possible. If we do use 27, the runway has to be closed for a runway inspection for some reason.
Did this trip on the weekend and decided to delay the takeoff out of SIN to be there about 6.00 and also carried a few tonnes extra in case there was queue to land.
Of course while we taxying out to 02C, someone managed to hit a bird on take-off and so we had to wait 20 mins for a runway inspection, and ended up running late anyway.
The roast duck in the airport canteen would have been nice and tender next morning though!!!
