Hello.
DC10, regarding the comparison between Spain and UK, i think you misunderstood the point (or maybe me?). The air traffic control system is three times more expensive in the UK, which doesnt mean that you earn three times more. Actually that is impossible, besides the fact that i read in a study about european air traffic controllers wages that we earn a little more than you do. It must be some problem with your air traffic management or some expenses that right now i cant figure out.
I can be wrong, but dont take that report that states NATS is very expensive like if you british controllers earned too much. The big money is somewhere else.
Best regards.
