Vueling didn't hand back their based aircraft slots for the summer by the Jan 15th deadline, but as yet no recruitment has taken place so probably not going to happen as I think it's too late to get a base recruited and flights on sale in time for May/June (as a side note the Norwegian EDI max base started recruitment a few weeks ago).
If DUB also took the Norwegian flights from MAN then that sucks big time, as it's not like there ain't a significant network in place for the size of country as it was!
