The Lufthansa Group said the cancellation of less profitable routes, focused largely on its hub airports in the German cities of Frankfurt and Munich, would save the equivalent of approximately 40,000 metric tons of jet fuel.

The company last week shut down one of its regional subsidiaries, CityLine, to cut costs. It said a "planned consolidation" within its European network also would involve Lufthansa Airlines, Austrian Airlines, Brussels Airlines, SWISS and ITA Airways, and hubs in Brussels, Rome, Vienna and Zurich.

The price of jet fuel has more than doubled in some markets since late February, when the war began with U.S. and Israeli strikes on Iran. Airlines are particularly vulnerable to fuel price shocks because jet fuel typically accounts for one of their largest operating expenses.
