Airlines have been hit hard as they struggle to obtain enough jet fuel to maintain their regular flight schedules. In July, several European airlines announced that they were at risk of running out of jet fuel. Before the war, Europe relied on the Middle East for roughly half of its jet fuel imports. The U.S., Nigeria, Canada, India and South Korea have all stepped in to provide Europe with jet fuel. Ryanair’s CEO Michael O’Leary said the company’s conservative hedging tactics have helped keep it resilient to rising jet fuel prices.
