Due to the rapid developments in Afghanistan, most airlines avoid flying over this state. Many carriers have security concerns over the Taliban's takeover.
The consequence of this is that detours have to be flown. This increases flight times, which leads to delays until the plans are adjusted. How long the measure will last cannot be estimated at all at the moment. Civil air traffic at Kabul Airport has been suspended due to the security situation.
At the moment, states like Germany and the USA are trying to fly their personnel and citizens out with military aircraft. There were dramatic scenes at the airport, because many Afghans are trying to leave the country and are hoping to get a seat in a plane. There were so many people on the area that the runway was temporarily blocked by crowds.
While the United States “fills” its transport aircraft with people up to the absolute maximum weight that can be taken off, an Airbus A400 of the German Air Force left Kabul Airport with only seven passengers on board. How long Kabul Airport can still be used is completely open. The security situation is reassessed every minute.
