Swiss International Air Lines said it currently has enough jet fuel supplies for six weeks but is preparing contingency plans amid growing concerns over potential shortages linked to the ongoing Iran conflict.
Chief executive Jens Fehlinger said the airline’s fuel outlook remains stable for now, with suppliers including oil companies and refineries continuing to provide reassuring forecasts.
However, European airlines have recently warned that tensions involving Iran could disrupt global fuel supplies and drive energy prices higher, raising concerns ahead of the busy summer travel season.
Fehlinger noted that if shortages begin to emerge, they would likely affect parts of Africa and Asia first, adding that no immediate warning signs have appeared in Europe so far.
Despite the current stability, Swiss and parent company Lufthansa Group are exploring emergency measures, including “tankering,” a process in which aircraft are fully fueled at airports with stronger supply availability before carrying extra fuel to destinations such as Zurich.
The airline is also considering strategic refueling stops at airports with stable fuel reserves, including Vienna for some Asia-bound routes.
Fehlinger added that prolonged increases in oil prices are expected to gradually impact airfare prices. He explained that the airline has reduced exposure to market volatility by hedging 80 percent of its kerosene needs for 2026, limiting fuel cost increases to around 20 percent so far.
