The cabin crew was excellent especially considering the stress they've been under and that their not paid for all the preflight work they do. The entertainment screens in the bank of seats that I was sitting in didn't work for the entire 8 hour flight. I consider this a failure on management's part to properly maintain their aircraft to ensure a pleasant experience for their customers.
