The work stoppages at the three airlines also coincide with the start of the summer holidays in the German state of North Rhine-Westphalia. It is to be expected that there could be numerous failures in Düsseldorf, Cologne/Bonn and at other airports. According to the current information, the airlines Ryanair, Lauda Europe and Easyjet are affected. However, the competitor Eurowings, for example, is suffering from an acute shortage of staff, so that it cannot be ruled out that there could also be isolated failures here.
