We had an enjoyable and comfortable flight from Sydney to Hanoi. The service was good but not great or to expectations. The inflight entertainment was quite good with enough selection to while away the time. The food was quite nice however I was very dissatisfied with the lack of supply as I was told that my selection wasn’t available as they had none left and would I choose something else, which I begrudgingly did , only for the lady behind me to order the same thing I wanted , and low and behold they had one! Wtf! Albeit a 4 star service apparently but if you pay for a business class service, you expect better than this. Another thing was the lack of service between meals, everyone seemed to disappear to the galley. We were provided a small bottle of water and I like to drink plenty of water on flights so got up to ask for some more only to be told they had none left, so the steward poured me some out of his bottle! The other thing was that there were no snacks offered during the flight between meals either which I find very lacking as well. Overall I felt like this didn’t come close to what business class should be.
