This website look so unprofessional I suspect it's fraudulent. Hogwash. I suspect the article in the Business Traveller fell for it too.
Why would Star Alliance need its site to be hosted by some internet domain registration company??? Star-Alliance.co.uk has no connection whatsoever to Star Alliance, I am afraid, and this site was set for a purpose that eludes me at this time but will certainly become clear at some point.

As I tell my students, the internet is a great resource IF one applies a modicum of discriminating personal judgement in analyzing the garbage found on it.
