By the way, I note that Helsinki is now in the poll section on LCY's website. So obviously a service could be operated from LCY's runway (assuming that the marketing folks have consulted withsome ops people).
Still in the poll section VIE, BCN and EXT. I would expect VIE und BCN to be BA Cityflyer's prime targets for new routes. Not sure if *A would react with a VIE service if this should happen.
As for BA Cityflyer, are all those 8 RJ100s busy from morning to evening or do they sit idle on the ground somewhere on the continent for longer periods of time? Even though their schedule is quite decent, I have difficulties seeing them operating 40 or so flights a day from LCY.
P.S.: Is there a complete schedule for LCY available on the net? This route-by-route menu at LCY#s website is a real pain.
