It seems to me that the airport's operators and GTE are rooting around to try to find a route which sticks - over the past couple of years they've tried Geneva, Guernsey (or was is Jersey?), Palma, and now NYC via Dublin. Part of the problem I see is that they don't appear to advertise the flights very widely - if Ryanair were their they'd have billboard adverts in and around the city etc etc. Also, some clarity over flight-only prices would be helpful, instead of these confusing flight & accommodation offers.
Seeing as the operators obviously read and take on the advice proferred within this thread, I look forward to the announcement regarding the new passenger terminal...
