I'm just surprised that no-one has picked-up on the fact that for a good few years the German for Vienna was not Wien, but rather Bratislava!
Considering how hard it is to fly to VIE from anywhere in the UK outside London, I'm quite happy with BTS, it is more than close enough.
Now they are back in Malmo, I'm still waiting for that to be badged as Copenhagen (E) - although in that case CPH is a better bet for either Copenhagen or Malmo.
