Rich,

Thanks for the recommedation about airfares.com.sg. It was EXACTLY the kind of site I was looking for.
I also have a couple of questions about the MAS bus from SIN to Johor Nahru:
1.Is it free for MAS ticket holders who are
flying out of Johor Bahru?
2.Do you have to call and make a reservation
for the bus or is it just "first come,
first served" until it fills up?
3.The MAS web site shows a transit time of
about 1 hour 45 minutes from SIN to the
Johor Bahru airport. Is this reliable or
often subject to delay at peak border
crossing times?

Thanks for your help.

Mike
