8.0 Very good
Flight crew was super friendly and helpful. Food was frequent and honestly pretty good. Plenty of on-board entertainment. Economy seats are super cramped for such a long flight, but the crew allowed people to get up and stretch, and kids could wander with their parents, so we all made it work. Overall a very good experience.
W

Standard flight with a drinks and a snack- overall very quick flight. The flight attendants were very strict, bordered on rude.
