The article's headline seems misleading: the article is actually about cargo, not traditional travel -- since airships are so slow.
But I don't see what needs this would meet -- either you need something to be shipped between continents quick (~overnight) so you use a plane, or you don't so you use a container ship.
This seems like it has neither the speed advantage of a plane, nor anything close to the size and scale advantage of a container ship.
So aside from the niche use of large deliveries to remote areas inaccessible by ship or rail... I'm not getting it.
