Warning strikes affect numerous passengers. Hundreds of flight cancellations at Lufthansa, closed security entrances to Hamburg and Frankfurt airports.

Large parts of German air traffic are paralyzed. Deutsche Bahn's passenger train drivers have been on strike for 35 hours since Thursday morning. Several hundred strikers gathered in a parking lot at Frankfurt Airport on Thursday morning for a rally. “Our wages should also take off,” said a poster attached to the stage. ‘We are worth it,’ said a banner on the building diagonally across the street.
