Transatlantic air carriers wishing to serve Ireland must operate at least an equivalent number of flights to Shannon as to Dublin. This is designed to ensure that Shannon receives at least 50 per cent of direct transatlantic services to and from Ireland. This policy is enshrined in the Ireland-US Bilateral Air Services Agreement.
Under the terms of this agreement, landings at Shannon and Dublin are counted over a 12 month period beginning in April in any year. This period coincides with one full summer and winter season. Because of this, it would not be necessary for operations during a specific period within the year, such as between 1 June and 14 September 1997, to comply with the requirements of the agreement.
I am satisfied that all airlines currently abide by these rules.
My Department does not inquire of airlines as to the reason for specific cancellations which are an operational matter for the airline concerned. I am not aware of any particular problem in this regard.
