Mark,
First of all, at no point did I say that the bus stopped at the airport. I said that the bus stops in Farranfore (which is a whole half mile from the terminal).
What I did say was that there is already a near hourly service from Cork to Farranfore, which takes two hours and which bugger all people use to catch flights.
Now I'm sure that once Neidin's regional bus hub is built at Farranfore, Bus Eireann can manage to divert the hourly bus by a whole half mile. I'm also sure that there will still be bugger all people getting a bus from Cork to Farranfore to catch flights.
