Had a 13 hour flight from Chicago to Dubai. The business class on Emirates was first rate. The seat was terrific. It folded down into a sleeper and they provided a mattress. We were able to sleep soundly so that when we arrived in Dubai we were right on schedule. The crew was attentive and the entertainment package was extensive. The food was only adequate but there you were not left hungry. Overall, one of the best flights i have ever been on.
