Ryanair seems to have removed flights on ALL routes from Girona, Reus and also from Kos and Rhodes for S15, even those put on sale previously from other airports.
I kind of doubt they are going to stop flying from all 4 of those airports. There could well be some sort of negotiation going on for sure, good or bad???
Still doesn't explain the absence of Almeria, Cork, La Rochelle and Riga as flights to other destinations from those airports are on sale. Would be really surprised if Riga were axed though, always seemed quite popular and is up to 4x weekly this winter.
