EasyBaby :
The VIE-SIN-MEL flight is on a 777, with a 1.5 hour break in Singapore in the middle of the night. Get out, walk around, get plenty to drink, preferably just water. Plenty of good Oz wine and beer (and Bundaberg rum
) when you get there !
As I'm sure you know routings vary but a typical one will be over Hungary, Romania, The Black Sea, Sochi in Russia, Georgia, The Caspian Sea, Afghanistan, right across India, over the Bay of Bengal, Medan in Indonesia, and to Singapore. Thence on across Indonesia and right across Australia. I assume the 777s have PTVs for you to follow progress.
I don't know how much Austrian use the Lauda name nowadays, as Niki Lauda has started his own competitive Niki airline.
