Getting the flights is one thing, filling them is another. When Slattery's put on a ORK-JFK charter inn 2005, it was warmly welcomed. However when push came to shove people booked on the cheaper scheduled flights out of Shannon.
Other lame excuses such as "my friend can't go on Thursday" and "my mothers sister wants to come back on Sunday" also led to people taking the journey to Shannon rather than supporting their local airports initiative. Best of luck to Knock but watch your back and keep Flyglobespan happy.
