LBIA, I believe the charters to Nice (spread over a 4 month period) are for a private company and not for public sale (I forget the name of the company). They currently use the Jet2 Nice run a lot. I dare say Mr Meeson may have perhaps been a little hasty in his decision to drop Nice for the winter.
Hooded, As for the 2 more Jet2 destinations, I don't know what they are, I was hoping that someone else had some idea, hence the reason for dropping that in at the end of my post. I only know that there are 2 more to come. The rumour mill is generally suggesting Cyprus and Berlin are in the frame, but as we all know with Jet2 rumours, "never believe it till you see it"
