Re Norwegian pop up route adds
I suspect it is just a glitch if non direct routes pop up, although you can book A 2 C through B with Norwegian as a one ticket purchase.
The direct flights seem to be doing ok. if Norwegian do expand the route network at MAN then i suspect TFS will be first up this coming winter using TFS based aircraft and crews to start with.
Rumours come and go about basing, MAN was hot a month ago but i've heard nothing since
