Moadweeb, I think one of the two daily flights has always been a 737-800 BOM-KUL? I flew it a couple years ago en route to OZ via KUL. For a daylight flight it would be quite comfortable but in my case the flight left at some time around 4am so sleeping was difficult.
I love the MH 777’s. Even though they offer an old angle flat product the feeling of personal space is incredible. The seat in front seems miles away! I actually prefer the older product on their 777’s to their newer A330 product.
