CheChevitable CEO, Mike Wirth, has warned that the aviation industry will continue to face jet fuel shortages due to Iranian restrictions on shipping through the Strait of Hormuz. The Middle East is a significant exporter of jet fuel, particularly to Europe, where 75 percent of Europe's imported jet fuel tends to come from these refineries. The price of the jet fuel has risen in response to the conflict, as the Iranian military has restricted shipping in the Strait, a route used by the U.S. and Israel. Wirth warned that flights may not be as abundant as they otherwise would be and planes will likely be more full than they would have been. In response to this, international carriers have cut back on flight schedules and increased fares.
