I would expect a 777-200LR to start, potentially moving up at a 773ER if demand dictates. As I think I've said here before they had a rumored start date of July 1 of this year with Miami having been slated to start in October. Neither came through obviously but I would expect those to be the next two cities, followed by Chicago then Newark. After that it's anyone's guess. There are no major holes in the route map aside from Boston, Miami and Chicago right now.
