Lufthansa will cancel more than 900 flights Monday, affecting 113,000 passengers as a result of a flight attendant strike, according to a notice from the German airline.

The strike, which will affect the airline's hubs in Frankfurt, Dusseldorf and Munich, comes as the result of a continued dispute over retirement benefits. A representative of the company's board called the strike "unprecedented in the history of Lufthansa," according to a BBC report.

More than 2,000 flights operated by the Lufthansa Group are expected to proceed as scheduled. The strike does not affect the many Lufthansa subsidiaries including Austrian Airlines, Germanwings, Lufthansa CityLine and Swiss.

The union, known as UFO, described the airline's reluctance to meet their demands as "not comprehensible" given the billions it is expected to make in profit this quarter.
