Asia's aviation sector is grappling with a deepening jet fuel crisis as the Iran conflict disrupts global supply chains. Airlines from Vietnam to New Zealand have canceled flights as prices double since January, with United Airlines already cutting unprofitable routes. The Strait of Hormuz blockade has cut off Middle Eastern crude supplies, forcing Asian refineries to slash production.

Europe faces similar pressures within weeks, as the EU and UK depend on Persian Gulf jet fuel for roughly half their imports. Even the US, typically a net oil exporter, sees vulnerabilities in regions reliant on Asian supplies. Energy analysts estimate a 600,000 barrels per day drop in global jet fuel output in March, coming just as travel demand ramps up for summer.

Governments are taking defensive measures, with China curbing exports and South Korea considering redirecting fuel to domestic markets. The International Energy Agency's release of 400 million barrels of crude offers limited relief, as most won't reach the aviation sector. Industry leaders warn that higher fares are inevitable as airlines pass on surging costs to passengers.
