Singapore airlines mate ,they really look after you .

The air hostesses are beautiful ,and everything is very clean in the plane and Singapore airport is nice .for the transit stop over .
enjoy your trip .i think you can take 32kgs ..being a international flight .
so bag plus board ,no problem ...book early ..as flights get more$$ as seats run out ,
i left it to last minute and it cost me a extra 600.

I have been on a number of Singapore Airlines (and Silkair fly from Singapore to the Maldives) and have had up to 9'6" (the big flying objects double-board bags) without issue. I don't know the official policy but they are pretty good.

Mate went to the Maldives last year and Singapore Airlines is definitely the go. We had eight guys with double and triple board bags and had no difficulties at all. Also ask for the 30kg baggage allowance.
