I have taken Aeroline several times in the past for trips from Singapore to KL and chose them primarily because of their very convenient drop off point at the Corus Hotel. The location is situated a quick one block walk from the KLCC LRT Station and from there a short ride to KL Sentral and the Hilton.

I would rate the experience with Aeroline as "OK." Not super luxurious by any means but they arrived on time. However, on the couple of times I rode with them, I objected to their decision to broadcast a movie throughout the bus at very high volume. Repeated pleas from myself and my Singaporean seat mate to turn down the volume a bit fell on deaf ears. Well, I guess I can understand why they were deaf.

Anyway, on more recent trips to KL, I have been quite happy with the inexpensive fares provided by Air Asia, followed by a relatively comfortable 45 minute bus ride with the nine ringgit red bus or eight ringgit yellow bus to KL Sentral. That being said, I was already at Changi so taking the flight versus the bus made more sense to me.
