Air Travel and Insurance Costs Spike on Iran Airspace Closure
Theater: Iran
Time horizon: 24h
Published: 2026-05-22
Moderate confidence (70%)
Risk direction: volatile · Impact: MEDIUM
Executive summary
Within 24 hours, airlines will reroute flights to avoid western Iranian airspace at night, increasing flight times and fuel costs on some Europe–Asia and Gulf–Europe routes. Aviation insurers are likely to widen war-risk premiums for routes near Iran and the Gulf, though commercial traffic will not halt entirely. Some carriers may announce temporary suspension or adjustment of schedules to/from Iran and neighboring states. Contrarian scenario: partial re-opening of airspace for certain corridors under strict coordination if diplomacy makes progress.
