Mr. Bryan Bourke:

It is less likely. We get notice that this will happen. The management team is quite proactive, notify and try to manage it into quiet times and has been successful at that. It notifies the airlines and manages it very well. It is very common. A friend of mine was coming back from New York during the summer, their Aer Lingus flight was cancelled and they blamed Aer Lingus but actually it was a problem with air traffic control in either Canadian or US airspace. It was a similar problem that was about capacity.
