Steve Mutton flies aboard SQ422, from Singapore to Mumbai.
Class: Economy, unfortunately, and waaaaay down the back in 58G (only one row behind me on this Boeing 777-200). The cabin felt a bit tired but it was clean and spacious (more leg room than on the Air NZ 787 Dreamliner I flew from Auckland to Singapore).
Price: It was bundled with my return flights home, but a search of Singapore Airlines New Zealand page gives a fare of around $970.
Flight time: The schedule said 5hr 20m, but the pilot said 4hr 30m before we left the terminal.
Unfortunately, a plane went through a flock of birds just as we left the terminal so had to wait on the taxiway while they checked the runway. In the end we arrived on time.
