A new strike by Lufthansa’s cabin crew is expected to disrupt the travel plans of around 100,000 passengers over the next two days.

The strikes, taking place today and tomorrow, will also affect services operated by Lufthansa’s low-cost subsidiary Cityline.

The walkout will hit flights at Frankfurt all day today and flights at Munich on Wednesday.

Lufthansa said the walkout will affect 100,000 customers. Already, flightradar24 is showing major disruption at Frankfurt airport today, with all Lufthansa flights this morning cancelled.

In a statement, Lufthansa said: “The UFO union has called on Lufthansa cabin crew to strike on Tuesday, March 12 in Frankfurt and Wednesday, March 13 in Munich. As a result, the airline will have to adjust its flight program on both days.

“Guests whose flights are affected by the UFO strike are currently being rebooked. This process has the highest priority for us and is still ongoing. We therefore ask for your patience.

“Guests whose booking has already been processed will receive information about the cancellation of their flight and, of course, rebooking options individually by email or in the Lufthansa app.”

The airline also warned that, due to a walkout by train drivers’ union GDL, train services will be ‘completely cancelled throughout Germany’ today.
