Maybe there is a specialty market to move mining equipment in and mined materials out or whatever. Maybe some opportunity to rotate some of those North Slope oil workers in and out for a little R & R, though I question it. Considering the money they pull in, they're going to prefer a two hour flight in and out of Anchorage for R&R, not a day or so on an airship.
I see far more viability on some well established route such as Boston to Dublin, New York to Tokyo or whatever.
I will say that I would give it a whirl. They probably are much safer now (famous last words).
