For the time being, Munich Airport will not get a third runway. This was stated by Bavaria's Prime Minister Markus Söder in a speech at the CSU parliamentary group meeting.
In view of the massive slump in air traffic due to the corona pandemic, there will be no more efforts in this direction during his term of office. The current numbers would strongly suggest that it will take some time for the aviation sector to recover. Therefore, it is currently a challenge to maintain a runway in Munich at all, "let alone the second or even a third".
Anyway, you have to inject money into the ailing airports. This is now needed to “keep the airports alive and strong”. Not to have another runway built. And maybe for a long time to be like No. de reported.
