if you want a more up-to-date list i suggest contacting servisair... only thing i have noticed is:
Air Malta seems to now operate from BHD (unless they have mixed the airports up which is unlikely)
Air transat has no available flights in june/july (tried some random dates, might have picked unlucky days..), doesnt say if its full or not operating..
Spanair isnt showing any available flights
Croatia airlines has no bookable flights but has been in BFS 3 or 4 times now
CSA has no flights on website
