South Eastern European Night Free Route Airspace (SEEN FRA)
On 30 March 2017, DANUBE FAB ANSPs together with HungaroControl introduced major changes in the airspace structure of the three States, by bridging the airspace between the two Functional Airspace Blocks of DANUBE FAB and FAB CE. This will allow Airspace Users complete freedom to plan routes during the night, throughout the combined airspace of the three States.
