The war in Iran has disrupted one of the main aviation corridors linking Europe and Asia. The European Union Aviation Safety Agency (EASA) has issued safety bulletins warning of high risk to civilian aircraft in Iranian airspace and surrounding regions affected by military activity, missile launches, interceptions, and air defense operations. A separate EASA bulletin covering Iran, valid through March 31, describes a high risk to civil flights at all altitudes within the Tehran flight information region.
The consequences reach far beyond the Middle East. Since Russia’s full-scale invasion of Ukraine in 2022, most Western airlines have been unable to use Russian airspace. With Iranian airspace now considered unsafe for normal commercial transit, the map for long-haul traffic between Europe and Asia has become extremely tight. Reuters mapping of global flight paths shows airlines diverting north via the Caucasus or taking longer southern routes through the eastern Mediterranean and the Arabian Peninsula. Many passengers traveling between Europe and Asia still transit through Gulf hubs. However, airports across the region, including Dubai, Abu Dhabi, Doha, Kuwait, and Bahrain, have faced disruption and unstable schedules during the conflict.
Central Asia sits just beyond that northern bypass. It is not replacing the Gulf as a passenger hub, and is not suddenly becoming the main bridge between Europe and Asia, but the region’s airspace is increasingly strategically valuable as the number of efficient alternatives shrinks. The war has made Central Asia more important as part of a wider arc stretching from Turkey and the Caucasus across the Caspian basin and onward toward South and East Asia.

Kazakhstan is the clearest example. Local airlines had already begun to adjust before the current escalation reached its present level. In January, The Times of Central Asia reported that Air Astana had rerouted flights to Sharm el-Sheikh, Dubai, Doha, and Medina to avoid Iranian airspace. After the conflict widened, Air Astana canceled flights to several Middle Eastern destinations following the closure of Iranian airspace and rising regional tensions. Kazakhstan also imposed a temporary ban on flights over or near the airspace of Iran, Israel, Syria, Iraq, Jordan, and Lebanon.
Uzbekistan also moved quickly. As early as October 2024, Kun.uz reported that Uzbekistan Airways was avoiding Iraqi airspace and western Iranian airspace on safety grounds. After the latest escalation, on March 4, Uzbekistan suspended flights to six Middle Eastern countries. The pattern is clear: Central Asian carriers are not immune to the crisis; they are already adjusting networks, schedules, and commercial risk, with the broader economic consequences of the conflict emerging across regional supply chains.
However, the region’s aviation systems clearly now carry far greater strategic and economic importance than they did only a few years ago. On its official site, Kazakhstan’s air navigation provider Kazaeronavigatsiya states that in the first half of 2025, it served 216,616 flights, including 161,029 operated by foreign airlines and described as transit and landing traffic. Kazakhstan’s aviation sector is also growing fast. In 2025, the country’s airports handled 31.8 million passengers, while Kazakh airlines carried 20.7 million. These figures point to an aviation system with real regional significance rather than a marginal market.
Uzbekistan is moving in the same direction. The government has made aviation expansion part of a broader transport strategy, with plans for a new major airport in the Tashkent region reflecting ambitions that go far beyond domestic demand. Tashkent is not Dubai, but it is steadily emerging as an important regional hub at a time when established corridors to the south are under growing strain.
None of this means Central Asia will see a sudden windfall. Longer detours increase fuel burn, crew expenses, insurance premiums, and schedule risk. Much of the region’s added strategic value may first be felt in overflight planning, air traffic management, and route resilience rather than headline passenger numbers. Nor does it mean airlines will quickly shift large volumes of passengers through Central Asian hubs. Gulf airports still possess far larger networks, deeper fleets, and more developed connecting systems.
But geography has become harsher and more political. Iranian airspace is unsafe, and parts of the Gulf corridor have been disrupted. In that environment, countries able to offer stable airspace, competent air traffic control, and reliable infrastructure gain importance.
That is where Central Asia now finds itself. For years, the region’s governments have spoken about the strategic value of their territory for rail, road, and trade corridors. The war in Iran has quietly added aviation to that argument. In a world where established east-west routes are narrowing, the skies over Central Asia matter more than they did before.
