Strategy is clearly focused on Internal Spain routes with 80 plus out of 130 flights internal ones.
It makes sense to add on some International routes as that keeps Aena happy and makes a statement on intent.
In relation to Lon - BCN well BA and Easyjet previously had 6-8 flights day from LGW now down to 4 since BA walked away.
Pretty likely some of these routes will drop off but given what Michael Cawley (?) stated that they launch routes without analysing them to death and some will never work but many do.
I don't envisage a pull out from Girona and Reus as all the aiports managed by same group so it will be a matching of routes over time.
