Cabin crew held a strike over pay and pensions for two days last week, resulting in the cancellation of one in five flights, affecting around 180,000 passengers and costing the airline 10-20 million euros ($11-$22 million).
The UFO labour union is obligated to "maintain industrial peace," Lufthansa said in a statement. "Strikes are accordingly excluded for the time being."
Lufthansa said UFO's demands for higher expenses and purser allowances would be discussed.
The parties will hold a joint press conference on Thursday to announce details.
