We were delayed over 5 hours so this did not help the flight. Then we were given overcooked eggs for breakfast after take off, instead of the dinner that they had asked us our choices. I am always disappointed lately that the only chocolate they have on board are disgusting Snickers bars and Twix. What happened to good chocolate? They used to carry Godiva. Dinner was given before we landed in the morning. This does not help us get adjusted to the time change.
