I am now visiting beautiful Chile. Flying from KUL to Chile is very far away.
Part 1 (KUL - SYD) : 7 hour 30 minutes
I took budget long haul carrier, AirAsia X.
At Sydney, I took a brief rest and looking around Sydney before flying into LA800 from SYD to SCL, via AKL. The awesome thing is that SYD airport to the city centre (say, Circular Quay) is less than 20 minutes by train. I stayed SYD to get enough rest.
My experience: flying from ASEAN to Chile
