Most crew members were friendly however, they seemed stressed and rushed from boarding thru dinner. Many passenger movie screens did not work on the plane and this was a seven and a half hour flight. The seat sizes on this plane were very small. Also the arm rests do not raise or lower. It’s one thing that I am a large woman but my hubs who is not large only tall was crammed in like a sardine. It was crazy. Never again.
