A Norwegian airline has said planned flights from Cork to the US have been postponed pending receipt of a permit to enable the flight plan to commence.

A spokesperson from Cork Airport has said the airport is awaiting a receipt of Norwegian Air International's foreign permit from the US Department of Transportation. The matter has now entered arbitration between the EU and US authorities under Open Skies.

A Cork to Boston service had been planned to begin in May with a service to New York scheduled for 2017.

However, Norwegian Air Shuttle ASA Chief Executive Bjrn Kjos said while direct flights between Paris and the US will begin this summer, the Cork service is on hold.

The Paris flights underscore the ambitions of Europe's third-biggest budget carrier to rapidly expand its long-haul business from the United States.

The airline has relied on the fuel-efficient 787 jetliner from Boeing Co to keep its costs low and cut fares on trans-Atlantic routes dominated by traditional flag carriers.
