What date?
How are you getting back from BKK or where is your onward travel after BKK?
Just had a quick look at JQ ex DRW to BKK via SIN & most dates in Feb are around AUD218.00 to AUD238.00 so IMHO do your DRW/BKK booking in the one pnr then flying up the day before of a cheap fare either QF JQ or DJ.
With the $$$ you save doing it that way you'll have more than enough coin for your nights accommodation in DRW & SIN unless you sleep at Changi Airport.[h=3]Booking Summary[/h]
