Actually the second runway at Malaga is been used occasionally as the airport is handling a lot more traffic this summer although I admit it was really a waste of money. Regarding the AVE high speed trains they certainly have reduced the number of domestic flights in Spain - especially Barcelona-Madrid - and with another 1,000 kilometres of track coming on stream this year domestic services will be further eroded plus the rail fares are quite reasonable not like some country I could mention!
Regarding Cuidad Real - passed by last year, excellent infrastructure but only has a small catchment area but good luck to the new owners - they will need it.
