Correct me if im wrong however during July and August the airport is open all day. Possibly for June as well.
The go ahead was given to schedule flights in possibly by AENA and then over ruled by the military. I heard that the fuel station had to be moved from where they had put it.
As Jet2 have been flying into mjv for the past 5 -6 years I dont think they would change their programme unless they were told it would be open.
