Planning a trip to SE Asia. I have a flight into Hanoi and want to spend time in Vietnam working my way down to SGN, also want to stop over in BKK, Philippines, KUL and need to reach SIN for my exit flight. Flights do not seem to be super expensive once you are in the region but I am wondering what programs may be good for travel redemptions within the region. Particularly ones that will allow layovers between two stops so I can try to organize my travel to get the most bang for my redemptions.
