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.

A strike at Germany's Hamburg Airport has left all outgoing flights cancelled Monday, with more airports likely to soon be affected.

Air traffic at Germany’s major airports ground to a near standstill on Monday after labor union Ver.di called on ground personnel, baggage handlers and security staff to go on strike.
