German airline Lufthansa founded 1,300 flights on Thursday due to thousands of flight attendants on strike.
The UFO, the airline's trade union, said in a statement that the strike was inevitable because both the airline and the flight attendants failed to find common ground in the labor negotiations.
NPR reports that the strike affects 180,000 passengers.
"Lufthansa and the union representing the flight attendants have been at odds for several months over the union's legal status, and a last-minute attempt by the airline to stop the strike failed after a Frankfurt court affirmed that the walkout was legal," NPR's Rob Schmitz to the station's Newscast Unit Thursday.
Local Germany, an English-language German publication, also reported that Lufthansa was forced to "scrape 700 flights on Thursday and some 600 on Friday," adding that while the UFO had agreed to several calls this weekend, the strike would not be shortened.
Germany's largest airline issued a statement on Wednesday, criticizing the strike.
"The Independent Flight Attendant Organization (UFO) has asked cabin crew to go on strike for two days November 7 and 8," the company said in the statement.
