Travel enthusiasts who are looking forward to travelling in June will notice restrictions in German airspace. Due to the NATO exercise "Air Defender 23", which is being held in German airspace, flight operations must be enjoyed with restrictions.
In June 2023, specifically from June 12 to June 23, "Air Defender 23" will take place, a NATO exercise in which numerous pilots in German airspace will simulate the course of war and train for it. During this exercise, flight operations will be completely cancelled for two hours a day, although the Air Force has promised to keep these inconveniences for air traffic to a manageable extent. During flight operations, airlines must fly around the closed airspace in order to be able to start their flight operations in accordance with standards, as the daily newspaper Frankfurter Rundschau reports.
