Several U.S. airlines have suspended Gulf routes and are avoiding Middle Eastern airspace following a spike in security threats after Israel’s strikes on Iran and subsequent missile exchanges.

American and United Airlines, among others, have diverted flights through alternative corridors over Egypt and Saudi Arabia, incurring higher fuel and operational costs.

Meanwhile, ongoing evacuations and repatriation flights continue amid a volatile environment that sees tens of thousands stranded or in transit, highlighting the precariousness of civil aviation in the region.
