If you read more deeply, you may see that the regional government are hell-bent on opening this ego-massager, yet AENA who run virtually all Spanish airports are very happy to continue using San Javier, which makes profits, has low operating costs and established routes and is only at around 70% capacity. Apparently the Air Force are quite content for the mix of military and civil flying. The Aeropuerto Elefanté Blanco would be privately run, and would have to persuade airlines to use it, without subsidising flights as of course this would be illegal...
If it ever happens, how long it would continue is anyone's guess.
Lunacy, IMHO.
