I believe it's departing daily for KL @ 8:00 & 22:00 via 2nd
Link.
ETA @ Pudu Raya in KL ~ 13:15 & 3:15 with 1 toilet stop ~ 10
mins.
I note of some suggestions from others of taking plane & ERL
etc.
However, overall i still find the coach (all the way) approach THE
preferred way to go SGP-KL or vice-versa, especially when
cost:benefit taken into account !
Especially the much reduced walking, getting up & down, the
more door-step like service & reduced 'hidden costs' etc.
The plane flight itself may be short BUT the waiting @ the
airports, walking up & down & in & out from bus to
plane to train etc. how much NETT time you really 'save' overall
?!?? Also note the total costs incurred ?!
If the bus-plane-train way is really so attractive between SGP-KL,
then Golden Mile, Lavender, Boon Lay etc. would have been deserted
long time ago !! Of course that isn't the case, most logically
& practically so.
