Asturias could become seasonal I guess. Iberia serve it as well, it’s a route that probably doesn’t need competition over the winter. I believe that is also quite a long established route.
Perhaps a decision to drop GLA was made in advance of FR dropping it, though I’d have thought enough time has passed by now to have reversed the decision. The route is served from SEN but if it really did cease from STN it would be quite a shock.
