A union representing Lufthansa flight attendants has called members at Frankfurt and at Berlin's Tegel airport out on strike as it escalates a dispute with Germany's biggest airline over pay and conditions.
The UFO union called on Berlin-based members to walk out for eight hours starting at 5am today, and their counterparts at Frankfurt, Germany's busiest airport, to follow starting at 6am.
UFO also plans to hit Germany's second-biggest airport, Munich, today. An 11-hour walkout there was set to start at 1pm.
The union opened its strike campaign with an eight-hour walkout in Frankfurt last Friday and warned of more to come if Lufthansa didn't give ground.
Lufthansa said the walkouts would force it to cancel "a majority of flights."
