I was thinking that yesterday! Because I'm sure Almería (or I might be thinking of Valencia) were part of Jet2's original compliment from Newcastle when they first started flights from here... It's a shame though because I'd like to see more of the smaller Spanish cities on our route map. Off to visit FTE Jerez in July and I'm looking forward to seeing "that side" of the costas Cádiz, San Fernando, Seville, Jérez etc.
With Jet2's new Jet2 holidays spinoff "jet2 citybreaks" I'm hoping some smaller cities might make a return, Spain's the kind of place a few weekly flights would work to most cities.
Edit: Graham beat me to it while I fannied on (without success) looking for some kind of proof
