NATO's largest aerial exercise, also dubbed "Air Defender 23," is bound to cause complications in airspace traffic over the next few weeks. For the purpose of this exercise, which is carried out in German airspace, airspace must be partially closed.

The NATO air exercise “Air Defender 23” is considered the largest air exercise in NATO history. The exercise will be carried out in German airspace until June 23rd. For the purpose of this exercise, however, airspace must be closed, which could lead to complications for flights during this period. Delays are already being implemented at Hamburg Airport, which is why passengers who have booked a flight during “Air Defender 23” should obtain extensive information in order to counteract the upcoming complications, as the Austrian Wings portal explains.
