According to the first paragraph of the article, these airships would ride the jet stream consistently traveling west-to-east across the globe thereby negating the issue of fighting against the wind. Not sure exactly how your comment relates?
I guess go all the way around. If you're not burning fuel to move, and time isn't a factor, there's no obvious downside. I would guess that a jetstream-bound airship taking the long way around would still be faster than an ocean-going container ship in most cases.
