250 planes sounds so optimistic. I'm not sure it's even possible to have enough planes delivered. As for wide bodies, there are no spots available for the 787 in the near future. I don't know about the A350 but I doubt it. About the only wide body aircraft I can think of are the retiring 767 out there. I'm sure someone will chime in with real numbers but I would not bet my career on flying wide bodies at Alaska.
