Lufthansa suspends Glasgow–Frankfurt route as Iran war drives European jet fuel prices up by 105%.
German aviation giant Lufthansa has suspended its Glasgow Airport to Frankfurt flight route, becoming one of the most high-profile casualties of the worsening jet fuel crisis sweeping across Europe — a direct consequence of the ongoing war in Iran that has sent aviation fuel costs spiralling to record highs.
The move will affect thousands of Scottish travellers who rely on the Frankfurt connection as a key gateway to destinations across Europe, Asia, and the Americas.
Lufthansa confirmed it is discontinuing its CityLine regional flights with immediate effect and cutting what it has described as "unprofitable" routes across its network in response to the surging price. The Glasgow–Frankfurt service has been among the routes axed as part of a broader cancellation of approximately 20,000 short-haul flights globally, which the airline says will save around 40,000 metric tonnes of jet fuel.
Passengers previously booked on the Glasgow–Frankfurt route will not be left entirely without options. Lufthansa has confirmed that services will temporarily transfer to Edelweiss Air operating via Zurich, maintaining some access to the wider Lufthansa Group network, which includes Swiss International Air Lines.
The crisis traces back to the war in Iran, which began in late February 2026 following military strikes launched by the United States and Israel. The conflict has severely disrupted global oil supply chains, with the closure of the Strait of Hormuz cutting off a critical passage for energy exports. The knock-on effect on aviation fuel has been devastating.
Jet fuel prices across Europe have risen by more than 105% since last year, according to the International Air Transport Association (IATA). The International Energy Agency (IEA) has issued stark warnings that Europe may have as little as six weeks of jet fuel reserves remaining, describing it as the largest energy crisis the continent has ever faced.
For airlines, fuel typically accounts for between 20% and 30% of total operating costs — meaning even a modest price rise cuts deep into margins. At current rates, many short-haul routes are simply no longer financially viable to operate.
Lufthansa is not alone. Across Europe, airlines are making painful decisions to protect their financial stability. Dutch carrier KLM has grounded over 150 flights, citing routes that are "no longer financially viable." Air France-KLM has introduced fare surcharges of up to 100 euros on long-haul return tickets. Aer Lingus has reduced its summer schedule by approximately 2%, impacting tens of thousands of passengers.
More than 150,000 international flights have been cut worldwide between March and June 2026 compared to pre-war schedules. The European Union is also considering temporarily waiving slot rules — regulations that require airlines to operate a set percentage of their allocated take-off and landing slots — to provide carriers with greater operational flexibility during the crisis.
