Piggybacking on this thread, thank you.
I'm flying HND - KUL - HKT on separate business class tickets, NH arriving at 0600 then MH departing at 0910. It will be my first time at KUL (and HKT). I saw that there is an immigration line for business class, so it should be no problem - without booking arrival service - to arrive, clear, pick up baggage, then check-in within the 3 hours?
