HAving never flown this far before I was a bit apprehensive but we did not encounter any unexpected problems. We were delayed taking off but then who isn't these days. The service was polite, attentive but not instrusive. There was plenty of food available with a good selection. Each seat had its own screen where you could follow the journey, watch lots of different films, which included old and new releases and also listen to music. Wifi was available. Our stop was in Doha, which was a lot shorter than expected due to our delay. The flight from Doha to Sydney was very long, but we were able to spread out abit as the flight was not full. I think that it would have been very long,tedious, boring and uncomfortable if the flight had been full.
P.S. As I am having trouble answering the questions that Tripadvisor have asked to rate, I will respond here.
