The route from San Francisco to Dubai (connecting there to other Emirates destinations) was previously planned to start in Summer 2003 and appeared in the Emirates schedules (and we discussed it on FT). It was to be one of the earliest A340-500 routes. It would route directly overhead the North Pole. It didn't go ahead at the time because of difficulties Emirates had getting approval from the US authorities.
Nothing in the EK schedules for this year yet.
