Too many optimists and spotters on this thread and not enough realists, Skyman and SWBKCB nailed it!
I think Bristol (whom we compared favourably a couple of year ago, and have since left us behind) have got a FRA service (thrice daily I think) and ABZ similar, but NCL has not even a sniff.
Nobody is prepared to take a chance, or prehaps they have done the math and it don't work.
With regard to Air Transat, it seems that Shannon (and Porto) was not initially loaded onto the system only to appear at a later date, only for Exeter and NCL to be canned. I'm wondering if Shannon were a little more proactive and convinced TSC that they were a better bet.
Maybe time the Board looked at their performance?
I think VentureGo might have a point. Jon Parkin might have been underhanded, but since he has departed and was replaced we seem to have gone steadily backwards at a greater rate that similar sized airports. I'm sure new owners (if it happens) will have a clear out, starting at the top.
