Pilots at Lufthansa ratcheted up a 35-hour strike on Tuesday, grounding many intercontinental flights by the German flag carrier, dpa reported.
Expanding the strike which began midday Monday with walkouts on domestic and European routes, unionized pilots refused to fly to and from Asia and the Americas and other far destinations for the strike's remaining 18-hour period on Tuesday.
Lufthansa said almost all its long-haul flights out of its main hub, Frankfurt, were cancelled.
