I doubt if the aim of a SEN-Saarbrucken route would be to attract tourists to Volkingen, as interesting and unique as it it. The city is nice for shops and restaurants, but is not in the same league as Berlin or Munich.
I was hoping the Saarbrucken route would be twice daily to London, so it would be in a healthy competition with the three airlines operating from LUX to London daily. Does anybody know the runway length requirements for a fully laiden FK100?
