Djerba,
I have no idea why the link for said forum no longer appears on the Spectators Balcony, though you can still find it at

Indeed, a push for the better utilisation of aircraft has driven the move as you say. My comment regarding the new ones was aimed at the fact that with Jet2 owning the majority of their fleet (of course excluding the 10 738s on lease) they are able to park them up for most of the winter, without significant costs (in leasing). I think this could see Jet2s very seasonal operation
begin to diversify, offering more Canarian/B&S roots and ski breaks during the quiet winter months.
