Iran Closes Airspace Amid Rising Tensions; Indian and Global Airlines Face Disruptions

Air travel across parts of the Middle East faced fresh disruption after Iran announced the temporary closure of its airspace, prompting several international airlines to cancel or reroute flights. Indian carriers, including Air India and IndiGo, confirmed that some of their international operations were affected as airlines prioritized passenger safety amid a rapidly evolving regional situation.

According to international aviation notices, Iran suspended access to its airspace during the early hours of Thursday (IST), allowing only limited international flights with special clearance. The move comes at a time of heightened geopolitical tension in the region, coupled with internal unrest within Iran, raising concerns among global aviation authorities.

Impact on Indian Airlines

Air India confirmed the cancellation of multiple long-haul flights, particularly on routes connecting India with the United States. Sources familiar with the matter indicated that services from Delhi and Mumbai to New York were among those affected. The airline stated that flights passing through Iranian airspace are now being rerouted through alternative corridors, which could result in longer flight durations and operational delays.

In some cases, rerouting was not feasible due to fuel constraints, leading to outright cancellations. Air India usually overflies Iranian airspace on westbound routes to Europe and North America, as it offers the most efficient flight path. However, with Iran’s airspace unavailable and Pakistan’s airspace already restricted, airlines are being forced to take significantly longer routes.

IndiGo, India’s largest airline by market share, also issued a public advisory stating that several of its international services were impacted by the sudden closure. The airline encouraged passengers to check their flight status and offered flexible rebooking or refund options where applicable.

“The situation is beyond the control of airlines, and our teams are working to minimise inconvenience to passengers,” IndiGo said in a statement.

Global Airline Response

The impact of Iran’s airspace closure has extended beyond Indian carriers. Several international airlines, including European and Middle Eastern operators, have altered flight paths or suspended select services to avoid the region. Aviation tracking data showed at least one international flight returning to its point of origin after the closure was announced.

Germany has advised its airlines to avoid Iranian airspace until further notice, while Lufthansa confirmed adjustments to its Middle East operations. The airline stated that it would avoid flying over both Iran and Iraq and operate only select daytime flights to certain destinations in the region as a precautionary measure.

Aviation risk monitoring organisations have noted that many carriers are choosing longer but safer routes, even though this leads to higher fuel costs and schedule disruptions. Industry experts say such decisions reflect a broader emphasis on safety amid uncertain regional conditions.

Reasons Behind the Closure

Iran’s decision to restrict its airspace comes amid escalating tensions with the United States and continued nationwide protests triggered by economic challenges. While Iranian authorities have not issued a detailed public explanation, global aviation bodies have highlighted concerns related to regional security dynamics and potential risks to civilian aircraft.

Flight-risk advisory platforms have warned that heightened military alertness or defensive activity in the region can increase the chances of miscommunication or misidentification, making precautionary airspace closures a standard safety measure during periods of instability.

Government Advisory for Indian Nationals

In response to the situation, India’s Ministry of External Affairs (MEA) reiterated its advisory urging Indian citizens to avoid travel to Iran until further notice. The advisory follows an earlier warning issued earlier this month, citing concerns over the deteriorating security environment.

The Indian Embassy in Tehran has also advised Indian nationals currently in Iran—including students, pilgrims, businesspersons, and tourists—to consider leaving the country at the earliest available opportunity through commercial travel options.

Officials stated that the government is closely monitoring developments and remains in touch with Indian citizens and airline operators to ensure assistance where needed.

Wider Aviation Implications

The closure of Iranian airspace adds to existing challenges faced by airlines operating westbound from India. With limited routing options available, flights are expected to take longer, increasing operational costs and potentially affecting on-time performance across multiple sectors.

Aviation analysts note that while such disruptions are not unprecedented, sustained restrictions could lead to schedule changes, fare adjustments, and continued uncertainty for international travellers.

What Passengers Should Do

Airlines have advised passengers to regularly check flight updates through official channels and remain flexible with travel plans. Travellers are encouraged to arrive early at airports, monitor airline advisories, and opt for rebooking or refunds where services are disrupted.

As the regional situation continues to evolve, further adjustments to flight schedules cannot be ruled out.
