They were talking to Aer Arann about possibly coming under their AOC, but I can't really see it happening because Aer Arann don't have the type on their AOC and if they went to all the trouble of getting the 146 added to their AOC, they wouldn't need Nex for anything.
Nex currently consists of a portakabin in Waterford and a few computers. The aircraft is in the UK somewhere on a storage maintenance program. There are no crews and no engineers. Most of the pilots seem to have gone to Efly so they won't be available to Nex.
And, as you say, it is really way too late now for a summer charter operation.
The Nex principals have deep pockets and so may hang on and try and make something work, but without an AOC, crews, engineers and only one (limited) 146, they have their work cut out.
It would be nice to see them back in the air, though.
