Banja Luka Airport has been closed for any traffic as of 15 January due to the reconstruction of its single runway. This effected the flights of Air Serbia only which were handled twice a week from Belgrade with ATR72 aircraft as Ryanair and Wizz Air suspended all of their operations to this airport in early January. The airport will be closed for traffic until 1 March.
"As we announced earlier, Banja Luka Airport will be closed until 1st March. We will use that time to reorganize and prepare for the next flight season so that the service provided by Banja Luka Airport is at the highest level" - the Airport said.
Beside JU flights to Belgrade, Wizz has not suspended Dortmund and Ryan Memmingen. But after info from BNX they both suspended these flights.
