The Lufthansa subsidiary Eurowings is extending the flight break on the Klagenfurt-Cologne / Bonn route until at least April 1, 2021. The carrier actually wanted to fly again in February 2021, but due to the further tightened entry and quarantine regulations on both sides, a new decision was made Shift.
Cologne / Bonn is the only international liner destination that is served from Klagenfurt, at least in theory, because the route is again on a break after being reactivated for a short time. Whether April 1, 2021 will stop for the resumption, depends on the further development of the corona pandemic in Germany and Carinthia.
Due to the fact that Austrian Airlines is pausing the connection to the Vienna hub - after a short break from the break between Christmas and New Year - Klagenfurt currently has no regular scheduled flights. It is still completely unclear when this situation will change.
