Germany’s flagship airline, Lufthansa, has been forced to cancel 290 flights as cabin crew workers went on strike at Frankfurt and Duesseldorf airports.
The cancellations affected 23 long-haul flights and stranded 37,500 passengers on Friday.
Following the strike Lufthansa told customers to visit its website or call its hotline at 1-800-850-6070 before heading to the airport
The company’s subsidiaries, including Austrian Airlines, Germanwings, Eurowings and Swiss aren’t affected.
The UFO union recently announced it would stage a week-long strike if its demands were not met. The union wants transition payments for its 19,000 members if they choose early retirement, among other expectations.
If its demands are not met the union plans to target various airports which would further affect Lufthansa’s ability to service customers. The UFO union said it would not target Munich’s airport through Sunday, which is the end of the southern state’s fall holidays.
