Whois shows the web site as being registered in Suffolk. Looking at the Linksair web site they are relatively new and their AOC was issued last year. As far as I can tell their aircraft was up for charter through Diamond Air Charter.
Learjet50, I disagree with you. I live in Oxford and I really believe there are plenty of people who will use a service to Edinburgh. Flybe or someone like that would have been nice, but at the moment we'll take anything over the train.
I just hope they don't crew their aircraft with snotty nosed wannabe fly gods from OAA.
