Deutsche Lufthansa AG, Germany's flagship airline, will cancel approximately 20,000 short-haul flights from its European summer schedule in response to skyrocketing jet fuel prices, which have doubled since the onset of the Iran conflict. This decision, effective immediately with the first batch of 120 cancellations, aims to save nearly 40,000 tonnes of jet fuel and reflects a significant operational shift for the airline. Lufthansa has been proactive in implementing cost-control measures, including the recent shutdown of its regional unit, Lufthansa CityLine, and grounding 27 older aircraft known for high fuel consumption. The airline is also facing labor unrest, with strikes affecting pilots and cabin crew. The broader aviation industry is experiencing similar pressures, with global airline capacity projected to decrease by around 3% in May as major carriers adjust to rising costs and geopolitical uncertainties. Lufthansa's restructuring plan includes plans to cut 4,000 administrative jobs by 2030 and shift more operations to lower-cost subsidiaries, highlighting the significant impact of fuel prices on travel economics.
