Interesting if Norwegian do see MAN as having too much competition, would be a step away from what they know where they were the 9th carrier on MAN-TFS, 6th on MAN-AGP and 5th on MAN-BCN but didn't seem to stop them. They compete on TATL from the largest competition market in Europe (London) and are apparently looking at DUB where there is much more competition than MAN from the outset.
Something doesn't quite sound right there, but I suspect it could be more that they didn't get the terms they were expecting from MAN? With TCX and VS expanding maybe MAN in a postition to say no to low offers?
