Thousands of flights to and from German airports are being cancelled as workers walk out as they increase demands for better pay.
The strikes at seven German airports, including Frankfurt, Munich and Hamburg, affected almost 300,000 passengers and forced airlines to cancel more than 2,300 flights - including those with easyJet, British Airways and TUI
Christine Behle of the Verdi labour union told public broadcaster RBB-Inforadio that failure to reach a meaningful deal with employers on pay could result in a "summer of chaos" at German airports.
