Berlin/London CNN —Lufthansa has canceled more than 1,300 flights scheduled for Friday after the Verdi labor union called for full-day strikes involving airport workers at seven German airports, including Frankfurt, Munich and Hamburg. Lufthansa, one of Europe’s biggest airlines, was ceasing all flight operations at Frankfurt and Munich for Friday, it said in a statement on its website on Thursday. It expects regular flight operations to be “largely back to normal” on Saturday, February 18. Overall, more than 295,000 passengers were affected across Germany, according to the airport association ADV. The Verdi union is demanding a raise of 10.5% for its members.
