Why EASA Warned Airlines to Avoid Iranian Airspace Due to Misidentification Risk

The European Union Aviation Safety Agency (EASA) issued a high-level advisory. The agency urged airlines to avoid the airspace over Iran. This warning was published on January 16, 2026. It was issued as a Conflict Zone Information Bulletin (CZIB).

EASA cited escalating safety risks from regional tensions. Iranian air defense forces are on a heightened state of alert. This greatly increases the potential for misidentification of civilian aircraft. The advisory noted a "high risk" to civil flights.

Heightened Risk to Civil Flights

The warning applies to the Tehran Flight Information Region (FIR). It covers commercial flights operating at all altitudes. EASA highlighted the presence of advanced weapons systems. This includes the potential activation of Surface-to-Air Missile (SAM) systems. Unpredictable state responses also contribute to the danger.

The regulator also advised caution in neighboring airspaces. This includes countries hosting U.S. military bases. Potential retaliatory actions could affect their safety. The advisory remains valid until February 16, 2026.

Geopolitical Context

The advisory follows a period of intense geopolitical uncertainty. The United States had threatened military action against Iran. This was linked to widespread nationwide protests. The protests began in late December 2025 over economic issues. They quickly escalated into broader anti-regime demonstrations. Iran had also temporarily closed its airspace on January 14, 2026.

Industry and Operational Impact

The EASA advisory is non-binding but carries significant weight. Many major European carriers immediately adjusted their operations. Airlines like Lufthansa, British Airways, and KLM are avoiding the region. They are rerouting flights over Central Asia and Afghanistan.

• Longer Flight Times: Rerouting adds significant distance to flight paths.
• Increased Fuel Burn: Longer routes necessitate higher fuel consumption.
• Operational Costs: Airlines face higher operational costs and complexity.
• Refueling Stops: Some extended paths require extra stops for refueling or crew changes.

Impact on Asian Carriers

The disruption is particularly critical for Indian carriers. Air India and IndiGo rely heavily on Iranian airspace. This is for westbound routes to Europe and the U.S. The continued closure of Pakistani airspace complicates their options. Air India canceled multiple flights to the U.S. and Europe. IndiGo services to Turkey and CIS countries were also impacted.

The International Air Transport Association (IATA) stresses the need for clear communication. The industry prioritizes safety over commercial considerations. Airlines are urging passengers to check flight status before travel.
