I have reviewed some older posts regarding the express bus services(Aeroliner,Transtar,etc), but they tend to be in the opposite direction. My concern is whether an 8 AM or 9AM departure from KL will arrive in SIN such that I can zip out to the airport for a 4:15 PM SQ departure. The airline schedule KUL-SIN requires a 12:00 noon departure at the latest. Which means leaving from central KL no later than 10AM. Not a big time saver and a lot more money.

I’m taking a 2 day excursion to KL because 5 days in SIN is too much time there. But if the logistics of the KL excursion are too daunting, I’ll skip it.

Thanks in advance.
