Transavia France, the low-cost subsidiary of the Air France-KLM group, confirmed on Sunday, April 26, the cancellation of several flights scheduled for May and June 2026, citing the surge in kerosene prices caused by the geopolitical crisis in the Middle East. These cancellations affect "less than 2% of the flight program over the May-June period," according to a company spokesperson. The decision by Transavia comes amid extreme tensions in the aviation kerosene market, a direct consequence of the conflict between the United States and Iran. Since the US-Israeli strikes against Iran on February 28, 2026, followed by the closure of the Strait of Hormuz—a strategic passage through which 20% of the world's kerosene used to transit—the price of a barrel of kerosene has more than doubled. Airlines now face an unexpected bill that undermines the economic viability of certain routes. "Due to the current geopolitical context in the Middle East and its repercussions on the price of aviation fuel, Transavia France is adapting its flight program and is forced to cancel several flights scheduled for May and June 2026," the company said in a statement. Affected passengers are being informed individually by SMS and email. The company offers them three options: rebooking at no extra cost, a voucher for a future reservation, or a full refund. "For the majority of canceled flights, a rebooking solution within 24 hours is offered," Transavia specifies. Europe is under the threat of a widespread shortage. The International Energy Agency (IEA) warned in mid-April that Europe would have only six weeks of kerosene reserves if oil supplies remained blocked. "I can tell you that we will soon hear the news that some flights from city A to city B could be canceled due to the lack of kerosene," said the IEA director. The International Airports Council of Europe alerted the European Commission about the risk of shortages as early as May if tankers did not resume using the Strait of Hormuz. If the situation worsens, French authorities have indicated they have some leeway. "There is no shortage at the moment," assured Maud Bregeon, government spokesperson and Minister Delegate for Energy. She specified that France has about 100 days of strategic kerosene stocks that can be released to compensate for potential volume issues affecting airlines. "These strategic stocks are initially intended to address volume problems, not price problems," she recalled. For ATPL and ATC students, this crisis highlights the critical importance of fuel management in flight planning and the impact of geopolitical events on aviation operations. Understanding how fuel price volatility can lead to route cancellations and operational adjustments is essential for future pilots and controllers.
