Lufthansa to Ground A340s, 747s as Iran War Disrupts Fuel Supply

Lufthansa is preparing for significant capacity reductions and the potential grounding of up to 40 long-haul aircraft as it confronts a severe jet fuel supply crisis triggered by the war in Iran. In an internal webcast, Lufthansa Group CEO Carsten Spohr announced the contingency plans, which target older, less fuel-efficient aircraft and could reduce seating capacity by up to 5%. The measures are a direct response to surging fuel costs and logistical disruptions that have jeopardized the airline's planned expansion into Asia.

The operational adjustments stem from what Spohr described as consequences “greater than we expected.” The effective closure of the Strait of Hormuz has severely disrupted global energy logistics. According to Vortexa data, this has interrupted about half of the European Union and UK's jet fuel imports, threatening supply chains and causing sharp price increases. For Lufthansa, this translates into an estimated €1.5 billion in additional fuel costs, driven by the airline's 20% unhedged exposure to market volatility. While the carrier has hedged 80% of its fuel needs, the remaining exposure is significant enough to force drastic action.

Operational and Fleet Impact

The airline's contingency plans involve grounding between 20 and 40 aircraft, representing a 2.5% to 5% reduction in available seating capacity. The aircraft targeted for removal from service are older four-engine models, specifically the Airbus A340 and Boeing 747-400, which are less economical to operate in a high-fuel-cost environment. Spohr stated, “We want to be prepared early,” indicating a proactive approach to mitigate financial damage.

In addition to the groundings, the conflict has forced widespread rerouting for Europe-Asia flights, adding between two and five hours of flight time and further increasing fuel consumption. To counteract the reduced flying in the Middle East, Lufthansa plans to redeploy capacity. The airline will add 1,600 additional departures during the summer season to destinations in India, including Chennai and Bengaluru, as well as to European tourist locations.

Stakeholder and Regulatory Pressures

The crisis affects a wide range of stakeholders. Lufthansa Group shareholders have seen the stock price decline by over 16% year-to-date and now face the €1.5 billion cost increase. Passengers will likely face higher ticket prices, as Spohr warned that unavoidable price hikes will “affect demand; fewer people will travel.” For flight crews, the potential groundings raise the possibility of short-time work programs, known in Germany as Kurzarbeit, a measure the German Federal Employment Agency (BA) can authorize to prevent layoffs during economic shocks.

These internal pressures are compounded by external strategic goals. Lufthansa is concurrently pursuing the acquisition of Transportes Aéreos Portugueses (TAP), a deal currently under antitrust review by the European Commission. The airline must now navigate a complex regulatory approval process while managing a severe operational and financial crisis.

Historical Context and Technical Analysis

This situation is not without precedent. During the COVID-19 pandemic in March 2020, Lufthansa grounded 150 aircraft and slashed capacity by 50% in response to a collapse in demand. Similarly, the closure of Russian airspace in February 2022 forced costly rerouting of Asia-bound flights, echoing the current operational challenges. In both cases, the airline demonstrated its ability to make rapid, large-scale network adjustments to preserve cash.

This development indicates an acceleration of an existing industry trend: the phasing out of four-engine widebody aircraft. The high fuel costs associated with the Iran conflict have made the continued operation of the Airbus A340 and Boeing 747-400 untenable, forcing an earlier-than-planned retirement. This crisis, while financially damaging, will inadvertently modernize Lufthansa’s long-haul fleet and lower its overall carbon footprint. It underscores how geopolitical shocks can act as powerful catalysts for technological transition within the aviation industry, prioritizing fuel efficiency as a critical component of operational resilience.

What Comes Next

The Lufthansa Group Executive Board is expected to make a final decision on the grounding of up to 40 aircraft during the second quarter of 2026. Meanwhile, the airline's network planning department has confirmed that the implementation of the summer 2026 schedule, which includes the redeployment of aircraft to India and Europe, will proceed as planned.

Why This Matters

This event highlights the acute vulnerability of global airline networks to regional geopolitical conflicts and their impact on critical supply chains. For airlines, it demonstrates that fuel hedging strategies, while important, cannot fully insulate them from severe logistical disruptions. The crisis serves as a powerful reminder that operational resilience depends as much on supply chain security as it does on financial instruments, forcing an accelerated transition toward more fuel-efficient fleets.
