Just wanted to report that the flight went ahead without incident, in fact it was perfect, no turbulence the whole way from Auckland to London - the seatbelt sign did not come on once. No sign of any ash cloud although I did see a lightning bolt a short distance from the plane as we flew out of Brunei...
I really got the impression that the pilots were trying to avoid turbulence which made for a very pleasent flight. It is a shame Royal Brunei have stopped this service from october as I would def fly with them again - the 777 was a very soomth ride...
