NATO exercise "Air Defender 23" will take place from June 12 to June 23. Hundreds of aircraft will train in German airspace, which will mean that civilian aircraft will not be able to use this space.

Civil airlines will have to fly around these areas to avoid restrictions. Air traffic will be blocked for about two hours a day in the northern, southern and eastern air training areas used for military purposes. If a flight is cancelled due to the NATO exercise, passengers have the right to alternative transportation.
