A ground crew strike at Berlin’s Tegel and Schönefeld airports is causing major disruption, with reports of over 650 flights cancelled.

The strike is taking place from 0400 today (Friday March 10) until 0500 on Saturday March 11, with the group website for the two airports warning of “severe disruption to air traffic”.

The site also warns that “After the end of the strike action restrictions in air traffic may continue”, and is advising “all passengers to enquire about the current status of their flights before travelling to the airport”.

According to a report by thelocal.de “the local Airport Association confirmed that almost every single flight out of and into both Berlin airports had been affected by the strike”.

The report said that passengers with Lufthansa, Eurowings and Air Berlin travelling within Germany have the option to convert tickets into Deutsche Bahn rail travel, while some international services are being re-routed to Hanover (around 270km to the west).

Representatives of Business Traveller attended the ITB tourism trade fair in Berlin this week, and were able to fly home as scheduled yesterday evening. But we have spoken to other attendees of the event who now find themselves stranded in the city.
