The CEO of Swiss Air says there isn’t a fuel shortage right now and is looking at backup measures.

“The forecasts from our suppliers – oil companies and refineries – are currently good,” SWISS CEO Jens Fehlinger told the Neue Müncher Zeitung.

Due to the U.S.-Iran confrontation, which has reduced supplies and caused energy prices to soar, European airlines have warned of possible jet fuel shortages within weeks, which might hamper the summer travel season.

Africa or Asia would be the first regions to experience a kerosene shortage. As of right now, there are no indications of that,” he told NZZ.

Fehlinger stated that the airline and its parent business, Lufthansa Group, were developing backup plans, such as “tankering,” in which planes would completely fill up at a location with plenty of supply, even while the prognosis is still stable.
