So -if Ryanair do set up shop in Copenhagen it might be a fair task to overcome some negative thinking about them. Maybe not- I expect Ryanair will have done their homework.
They will always be a market for them however its difficult for any carriers apart form flag carriers/DY based in Scandinavia to work. Not such a bad thing either.
CPH are unlikely to offer FR what they would like and it will be a case of pay what others pay or don't come to town.
