Hi everyone!
Many airports in Spain that serve both as a military airfield and a civil airport are missing in the sim.
I can recall, at least, LEZG (Zaragoza), LEVD (Valladolid), LEAB (Albacete) or LELC (Murcia San Javier). This one is now a military exclusive airfield as a new civil airport (LEMI) was built in recent years.
As you said in your post Zaragoza is a very important hub cargo in southern Europe and Valladolid is a destination for some Ryanair flights.
Maybe there is a request by Spanish autorities about national security concerns…
Greetings from Spain.
