My information is that Cork are not involved in any live negotiations with any transatlantic carrier.
A member of the CAA has had informal discussions with a very senior executive at Continental but I wouldn't be overly optimistic in the short term.
It will be difficult to compete with SNN even in a post stopover environment given the Mid West Airports tradition of throwing money at airlines and tour operators.
There's an election in the pipeline so why not milk the taxpayer while the going is good. Sure its worked for the past 60 years.
Cork has always been more cautious in its approach.
Neidin's Ryanair prediction is much more likely to happen and I understand that Aerlingus are also evaluating a major expansion out of Cork.
