Just read the USA today article. I do not read it as you will be able to go vacation there. You need to be a professional in certain categories and get a license to go. Or have family there. And only these licensed professionals can bring back up to $400 in goods of which a max of $100 can be cigars and alcohol combined. So basically a few cigars and a bottle of rum.
Check out this article from USA TODAY:

To keep it on topic, I doubt there would be enough traffic to warrant scheduled UA service. So probably just UA charter.
