One of Emirate claim to fame use to be excellent crew. But I think that has faded just a bit. While the first leg of my journey was impeccable, the second was good but not amazing. A few of the crew could have use a bit of smiley face, plus the sandwich served after take off was not good at all. I would have not served it at all.
