Well, I bet few people saw that coming. That's certainly a coup for the airport.
According to another website the CPH-NQY route begins on 28 June. There are no details of frequency or duration of the service. In the past SAS has operated short season summer routes from Stockholm to Bristol from the end of June to mid-August.
I wonder if SAS sees this primarily as a route for Danish tourists to visit Cornwall along the lines of the Eurowings routes from Dusseldorf, Berlin and Stuttgart.
