‍TEHRAN — Iranian authorities ordered a temporary closure of national airspace, disrupting international flight operations and forcing multiple airlines to reroute or cancel services.

Iran shut its airspace for several hours amid escalating tensions, triggering immediate operational responses across global networks. Airlines diverted flights away from Iranian airspace even after the formal closure ended, as carriers avoided elevated risk zones in line with standard safety practice.

Airlines Affected

Reroutes/delays:

• Lufthansa (LH) – adjusted operations, avoided Iranian and Iraqi airspace, rerouted flights into longer corridors.
• British Airways (BA)/ IAG group – canceled some services (e.g., flights to Bahrain) and avoided Iranian airspace.
• Several European carriers (e.g., KLM (KL), Finnair (AY), Wizz Air (W6), Ryanair (FR)) opted to avoid the entire Iranian/Iraqi airspace even after it reopened, extending routings over Afghanistan and Central Asia.

Cancellations / broader impact (background context):

• Lufthansa had already suspended flights to Tehran for safety reasons and extended the suspension.
• Emirates (EK) – previously halted some flights to/from Iran amid safety concerns (related broader context of the regional unrest).
• flydubai (FZ) and Turkey's Pegasus Airlines (PC) had suspended many services to Iranian destinations in recent related flight suspensions.
• Qatar Airways also canceled some flights to/from Iran across the same period of geopolitical tension.

Central Asian & Regional Airlines Rerouted

Air Astana (Kazakhstan) rerouted flights around Iranian airspace and adjusted services to destinations such as Sharm el-Sheikh, Dubai and Doha.

Central Asian carriers including Uzbekistan Airways (HY), Fly Khiva (2U), FlyOne Asia (7Q) and Jazeera Airways (J9) faced reroutes or forced returns because routes normally crossed Iranian airspace.

Indian Airlines

Air India (AI) confirmed that several long-haul flights to the United States and Europe switched to alternative routings, while others faced cancellation when rerouting proved unviable. IndiGo (6E) reported disruptions across its international network and activated customer recovery measures as operations adjusted to the evolving situation.

The disruption carried added significance for Indian carriers because Pakistan continues to bar Indian aircraft from its airspace. With Pakistani airspace unavailable, AI and 6E rely heavily on Iranian airspace for westbound routes to Europe, Central Asia and the Caucasus, leaving limited contingency options.

Flight tracking data showed that 6E’s Tbilisi–Delhi service became the last non-Iranian passenger flight to exit Iranian airspace before the closure took effect. Another 6E service operating from Baku to Delhi turned back to Azerbaijan as conditions deteriorated.

Iranian airspace has always been one of the most strategically critical east–west corridors in Eurasia. Any prolonged disruption increases block times, fuel burn and crew complexity for carriers already constrained by regional geopolitical barriers, with Indian airlines among the most exposed.
