Lufthansa cancelled four flights from German airports to New York, and four more coming in the other direction. This comes after the airline cancelled 13 flights during Monday and Tuesday. Air Berlin flights have also been hit - but a spokeswoman said on Wednesday one flight would head from each of Berlin and Düsseldorf to New York that afternoon.
As a hurricane is classed as an act of God under EU regulation, passengers who have had their flights cancelled are not entitled to compensation, Die Welt newspaper said. They should be offered a free flight home, but long waiting times are expected.
Mass evacuations have taken place in New York and the stock exchange was shut down on Monday as the east coast prepared for what could be a very violent storm.
