In mid‑January 2026, tensions between the United States and Iran escalated sharply. In response to threats of U.S. military action, Iran temporarily closed its airspace to most flights for nearly five hours, allowing only international flights to and from Iranian airports with special permission. According to official notices, the closure began at 5:15 p.m. ET on January 14, 2026 and was lifted shortly before 10 p.m. ET[1]. Flight‑tracking data showed that dozens of aircraft were forced to divert or delay during the short‑notice closure[2]. After the notice was removed, Iranian carriers such as Mahan Air and Yazd Airways were among the first to resume over‑flights[3]. The closure reflected concerns over potential U.S. military strikes and underscored the vulnerability of commercial aviation in the region.

U.S. Federal restrictions on flights in the Tehran Flight Information Region

Long before the January 2026 closure, the United States had imposed strict prohibitions on its carriers operating in Iranian airspace. Under a Special Federal Aviation Regulation (SFAR No. 117), the Federal Aviation Administration (FAA) bans all U.S. air carriers, commercial operators, and U.S.‑registered civil aircraft from conducting flight operations in the Tehran Flight Information Region (FIR), except when the aircraft is operated by a foreign carrier[4]. The FAA extended this prohibition in October 2024 for three additional years, from October 31 2024 through October 31 2027, citing continuing “significant unacceptable safety‑of‑flight risks” to U.S. civil aviation from heightened regional tensions and increased military activities[5]. The rule notes that the January 2020 accidental shoot‑down of Ukraine International Airlines flight 752 by Iranian air defence forces underscores the risk of misidentification of civil aircraft[6]. The FAA emphasises that the ban remains necessary because threats to U.S. civil aviation persist during periods of heightened military activity[7].

German and Italian warnings: recent NOTAMs

As tensions grew in January 2026, Germany issued a Notice to Air Missions (NOTAM EDWW B0036/26) that recommended all German civil operators avoid entering the Tehran FIR. The plain‑language content of the notice, reproduced by aviation risk databases, states that German operators should not enter Iranian airspace due to a hazardous situation and the potential risk from escalating conflict and anti‑aviation weaponry[8]. The directive, valid from January 14 2026 through February 10 2026, superseded earlier cautions and reflected Berlin’s heightened security concerns.[8] Italy’s aviation authority issued a similar NOTAM (LIRR E2877/25) on December 16 2025, urging Italian air carriers and aircraft registered in Italy to ensure robust risk assessment and contingency planning before operating in Iranian airspace[9].

The European Union Aviation Safety Agency (EASA) reinforced these national warnings. In a publicly available information note issued on September 30 2025, EASA advised all civil air operators to consider the potential risk in Iranian airspace when conducting risk assessments and planning routings[10]. The advisory applied to all flight levels in the Tehran FIR and remained valid until January 31 2026[10]. EASA’s note demonstrates that regulators across Europe view the airspace over Iran as a conflict zone requiring careful risk‑management.

Continuing U.S., U.K., and Canadian restrictions

Germany and Italy joined a broader set of long‑standing warnings. The United States continues to ban over‑flights entirely under SFAR 117[4], and a related NOTAM (KICZ A0011/24) reminds operators that the prohibition is effective from October 31 2024 to October 31 2027[11]. The United Kingdom’s Aeronautical Information Publication contains guidance recommending that U.K. operators avoid the Tehran FIR at lower flight levels, while France’s aeronautical circular AIC 15/24 and Canada’s AIC 21/25 similarly caution their carriers about operating in Iranian airspace[12]. These documents show that transatlantic regulators maintain a coordinated approach to mitigating risks from anti‑aircraft weaponry and potential misidentification.

Why airlines are diverting around Iran

A key reason regulators and airlines avoid Iranian airspace is the risk that civil aircraft could be misidentified as military threats during periods of conflict. Analyses of previous incidents note that Iran has conducted missile and drone activity near busy international routes with little advance warning, and the misidentification of Ukraine International Airlines flight 752 in January 2020 demonstrates the lethal consequences of such errors[13]. Aviation risk databases underscore that Iran has been testing ballistic missiles without issuing NOTAMs and that GPS interference has been reported in the region[14]. With regional tensions rising and multiple conflict zones intersecting, operators remain concerned about inadvertent engagements, particularly when anti‑aircraft defences are on high alert.

The January 2026 closure illustrated the practical effects of these risks. During the five‑hour restriction, missile and drone barrages across the Middle East posed a high threat to airline traffic[15], prompting carriers to divert around Iran or cancel flights. Flightradar24 data showed that dozens of flights that would normally overfly Iran either diverted via Saudi Arabia and Egypt or returned to their points of origin[2]. Such diversions lengthen flight times, increase fuel consumption and operating costs, and can necessitate additional technical stops.

Airlines’ responses: avoiding Iranian airspace

Many carriers responded to the heightened risks by publicly confirming that they would avoid Iranian airspace. Lufthansa Group announced that all of its airlines—including Lufthansa, SWISS, Austrian Airlines, Brussels Airlines and Eurowings—would avoid over‑flying Iran and Iraq “until further notice”[16]. The company also suspended overnight flights to Tel Aviv’s Ben Gurion Airport for several days due to the security situation[17]. The German carrier’s decision underscored that major European airlines see the region as too volatile for routine operations.

Indian carriers were also impacted. Following the Iranian airspace closure, Air India cancelled at least three U.S.‑bound flights and warned of delays on some Europe services. In an official statement, the airline said it was using alternative routings for flights that normally overfly the region and that some flights would be cancelled where rerouting was not feasible[18]. The alternative routes, which involve flying around Iranian airspace via Iraq and Saudi Arabia, require additional fuel and can extend flight times. IndiGo, another major Indian carrier, stated that it was routing all flights to Europe via Saudi airspace and warned passengers of possible cancellations for routes to Almaty and Baku[19]. These actions show that airlines in the Asia‑Pacific region are proactively adjusting schedules to avoid Iranian skies.

The U.S. prohibition means no U.S. commercial carrier overflies Iran[20]. Airlines from the Gulf have also adjusted: carriers such as flydubai and Turkish Airlines cancelled or rerouted flights in mid‑January 2026[21]. Lufthansa’s partner ITA Airways suspended night flights to Tel Aviv[22], while other carriers maintained daytime operations but prepared for cancellations if the situation deteriorated. Russia’s Aeroflot turned back a flight bound for Tehran when the airspace was closed[23].

Impact on flight routes and travel times

Rerouting around Iran generally requires aircraft to fly longer paths across the Middle East. For example, flights between India and Europe typically cross over Iran and Turkey; avoiding Iranian airspace means diverting south toward the Arabian Peninsula, adding hundreds of kilometres to the journey. Long‑haul flights between Asia and North America that once used the great‑circle route over Iran and Russia now have to circumnavigate multiple closed airspaces, further increasing flight times and operational costs. In January 2026, some Air India flights that would normally transit over Iran were rerouted via Iraq, leading the airline to caution passengers about delays and to cancel services where alternative routings were not feasible[24]. Lufthansa’s decision to circumvent Iran and Iraq likewise led to longer flight times and changed flight schedules across its network[16].

Broader security environment and travel advisories

The avoidance of Iranian airspace occurs against a backdrop of wider security concerns. Regional tensions escalated after Iranian officials warned that they would retaliate against U.S. bases if Washington launched strikes[25]. Several countries, including Italy and Poland, issued travel advisories urging their citizens to leave Iran or to avoid travel there[26]. These advisories reflect worries that civil aviation might become entangled in military confrontation or that airports could be targeted during hostilities. In addition, the European aviation community has been dealing with ongoing unrest in Iran and neighbouring states, with reports of internet blackouts and violent crackdowns on protesters[27]. These developments heighten the potential for miscommunication and misidentification in the airspace above the region.

Conclusion

The January 2026 closure of Iranian airspace and subsequent diversions underscore the precarious security environment around the Tehran FIR. Official prohibitions and advisories from the U.S. FAA, Germany, Italy and the European Union highlight enduring concerns about misidentification of civil aircraft and the presence of anti‑aviation weaponry. Airlines have responded by cancelling flights, rerouting long‑haul services, and avoiding Iran entirely. As U.S.–Iran tensions persist and regional conflicts continue to evolve, commercial carriers will likely maintain longer routes that circumvent Iranian airspace until safety can be assured. The confluence of regulatory prohibitions, national NOTAMs and airline risk assessments demonstrates a cautious approach aimed at protecting passengers and crews amid a volatile geopolitical landscape.
