I thought it was recenty explained to us that among the reasons that Qatar Air got its own forum was that frequent flyers didn't know that Qatar is in the Middle East and that Turkish Air was given its forum is that they had no idea of where Turkey was.
If that is the case, it seems that by putting all airlines into regional forums there is going to be a lot of confusion as people try to determine if, say, Portugal is in Asia or South America (or even, gasp, Western Europe).
