The major surprise to me if those route closures are correct is Nice, me thinks it was easJet´s second international route after Amsterdam way back in 1996. There is a very large ex-pat community in the area. I would think another carrier would take a serious look at the route. As for Krakow it is not far from Katowice where Wizz fly to (they do not operate any routes from Krakow I think due to cost) so another daily service to Katowice could easily take up the slack. As for Alicante - Monarch looks the obvious choice to add a few more sectors plus they could look at Paphos as I know of quite a few people who live near Paphos but travel to Larnaca to use Monarch instead of easyJet.
