New routes
I've yet to hear an Irish airport/airline marketing spokesman say that a route is not doing well.
"Sales are running ahead of expectations" or "the airline is thinking of expanding next year" are some of the well rehearsed phrases that are included in press releases issued to lazy journalists.
Over the years we have been treated to blazing publicity when a route starts and then an embarrassing silence when an airline meekly withdraws with its tail between its legs.
In fairness this is not peculiar to Shannon but smaller Irish airports in general seem to blow their trumpet louder in order to attract media attention.
Airlines come and go to Dublin all the time and hardly get a mention.
