Aer Lingus has not ruled out the possibility of establishing a European hub at Shannon, saying it's committed to developing its 'presence' at the airport.
Calls have been made for the airline to fly services to a major European city so that passengers would have more connectivity from Shannon to Europe and the rest of the world.
While Aer Lingus operates a seasonal service to Faro in Portugal, apart from London Heathrow, this is the airline's only European route. Aer Lingus Regional operates services to several UK destinations but they use smaller commuter aircraft.
Aer Lingus' last attempt to serve a major European destination lasted less than three months. In 2010, the airline resumed operations on the Paris route, which it had axed previously in 2001.
Clare Fine Gael TD Pat Breen has called on Aer Lingus chief executive Christoph Mueller to consider establishing a European hub at Shannon. "This would be the icing on the cake for Aer Lingus and Shannon if a hub could be established here. At the moment we have to go through Heathrow to get to Europe but we need a direct link to Europe and onward via Paris or Amsterdam."
