A one-day strike by workers at 13 German airports, including the Frankfurt and Munich hubs and all the country’s other main destinations, has caused the cancelation of most flights.

Hundreds of flights have been cancelled across Germany as airport workers stage a nationwide strike over pay, posing a major disruption for air travellers. The industrial action, led by the trade union Verdi, began unexpectedly on Sunday at Hamburg Airport, before expanding to a nationwide strike.
