Ryanair is moving a single aircraft away from Copenhagen in a dispute with Danish authorities.
The Iow-cost carrier’s chief executive Michael O’Leary blamed a “bizarre” labour court ruling for the decision.
He claimed rival SAS unions had been allowed to “blockade” the Ryanair aircraft based at Copenhagen.
“We have instructed our lawyers to challenge this bizarre ruling with the European Commission and the European courts since it allows SAS workers and their unions to interfere with competition, and the jobs of Ryanair pilots and cabin crew,” said O’Leary.
Ryanair plans to continue running 14 routes from the Danish capital using aircraft based away from the city, including a new service to Edinburgh from November.
The Copenhagen-based Boeing 737 will switch to Kaunas in Lithuania.
