Jet airliners don't run on crude oil, they run on avgas. Avgas average price has more than doubled in the past month, see below. https://www.iata.org/en/publications/economics/fuel-monitor/ China has stopped avgas exports, starving Australia and other importers. Singapore fuel brokers cannot guarantee supplies, even for airlines that have hedged. Air New Zealand announced earlier this month that their services would be extensively cut from next month. Vietnam's airlines are proceeding with the same procedure since their source has dried up. Over in the US, United Airlines is suspending a number of routes due to rising jet fuel costs amid the US-Israeli war with Iran. The Chicago-based carrier confirmed it will cut five per cent of its flights in the second and third quarters of 2026, from a network of 4,000 domestic and 800 international routes. In a letter to staff on Friday, United CEO Scott Kirby said the company was preparing for oil prices to climb as high as $175 a barrel.
