Switzerland's aviation infrastructure is confronting a significant challenge as jet-fuel reserves have fallen below the legal minimum, dropping to 72 days' worth of supply. The deficit stems from recent geopolitical disruptions, particularly a blockade affecting the Strait of Hormuz, which has sharply increased kerosene prices. Airlines operating in Swiss airports are facing increased costs, with some paying spot rates comparable to post-pandemic levels. Authorities are considering rationing measures akin to those during past oil crises, which could impact flight schedules, especially during peak travel periods.
In response, major Swiss airports such as Zurich, Geneva, and Basel-Mulhouse are implementing contingency strategies. These include procedures for fuel-carrying aircraft and rerouting kerosene supplies from refineries in France. Travel and airline companies are advised to adopt flexible scheduling and ensure bookings are refundable as fuel costs and supply security fluctuate. Additionally, long-term efforts are underway within Swiss policy circles to promote sustainable aviation fuels, although expected to come into use only by 2028. Until then, airlines and passengers will need to adapt to a more uncertain and potentially costlier flying environment.
