Extracts from the ICC meeting minutes state:-
"EMA has the potential to develop a vacant building into a second dedicated terminal and could fund this for a potential customer." and
"EMA confirmed consideration of using a second terminal as a business terminal"
There is no connection with the airport's "long-term aims" of attracting further long haul routes, only perhaps through an assumption that this possible development might encourage an airline to commence a route to a European hub.
The only building which could possibly form the basis of a second terminal would be the old Post Office hub. This would require substantial development, but it is close to the check-in hall and the elevated walkway runs next to it on the airside?
