Pros: It was a newer model of the plane that I flew out with and it showed. Excellent interior, food was better than the previous flight. Very comfortable and functional for each individual . Crew were fantastic in there dealings with the passengers Overall a very pleasant experience
Cons: The inflight entertainment was not as good as I expected. To the extent there wasn’t anything that I wanted to watch as I’d seen the only 2 films that I wanted to watch in my previous long haul leg. TV series were severely lacking in choice as was the latest movies.
