Lounge access with economy + business class flights?
I am flying SIN-KUL-BKK on Malaysian and have bid on an upgrade for the KUL-BKK segment. If that upgrade comes through, will I have lounge access for both legs. In other words if I show my Business Class boarding pass for KUL-BKK, will I be granted access to Oneworld lounges in SIN?
Assuming yes, which lounge do people recommend in SIN?
