Volodymyr Zelenskyy didn't just warn airlines this week. He warned their insurers too.

Last night the Ukrainian president declared that the "safe days in Russia's skies are over," and made a point of addressing not just carriers and airports but the insurers standing behind them. He argued Ukraine has no intention of targeting civilian aircraft, but that the sheer scale of Kyiv's own drone strikes into Russian territory now needs to factor into any risk assessment of flying through that airspace.

It's a rare instance of a head of state naming the insurance market directly in a wartime security warning - and for good reason. Coverage decisions on where an aircraft can safely fly, and who bears the loss if it doesn't come home, are exactly the kind of judgement call this warning is designed to unsettle.

A market already bruised by this conflict

For hull war underwriters, Russian airspace risk isn't a new file - it's one of the most expensive open cases on the shelf. Around 400 Western-leased aircraft, worth more than $10 billion, were effectively trapped in Russia after Moscow barred their export following the 2022 invasion, triggering a wave of litigation between lessors and their insurers that is still working its way through the London courts.

That case set a significant precedent for how "loss" gets defined when a conflict, rather than a crash, is what grounds an aircraft - and insurers including Chubb, Fidelis and Lloyd's have since sought permission to appeal parts of the ruling.

Zelenskyy's warning lands on top of that unresolved exposure, not alongside a clean slate. Since late August, Kyiv and the surrounding region have endured one of the most intense bombardments of the war so far - near-continuous waves of Russian long-range drones targeting energy sites, warehouses and residential buildings over several consecutive days. A single strike on an ammunition depot near Kyiv in that period killed at least 38 people, one of the deadliest single incidents of the year, and officials say the toll across the wider barrage has continued to climb as search operations conclude. Zelenskyy has framed Ukraine's response - a sharp rise in drone strikes deep into Russian territory, including against energy infrastructure and retail logistics sites - as an attempt to squeeze Moscow economically until it comes to the table.

The practical effect for underwriters is that "Russian airspace" is no longer a static line on a war-risk map. It's a moving target, shifting with the tempo of a drone campaign that both sides are actively escalating.

Who's actually still flying it

Most Western carriers rerouted around Russian airspace back in 2022 and have stayed clear ever since, eating longer flight times and higher fuel bills on Asia-bound routes as a result. The airlines still using the corridor are concentrated among carriers from countries that never imposed reciprocal airspace bans. Flight-tracking data puts Turkish Airlines as the most extensive user, serving seven Russian destinations out of Istanbul.

China's big four - Air China, China Eastern, China Southern and Hainan Airlines - account for the largest volume of overflights, mainly linking Europe to Asia. Gulf carriers Emirates, Etihad, Qatar Airways, flydubai, Gulf Air and Air Arabia continue to serve Russian cities and use the airspace for onward routes, while Air India relies on it for its US and Canada services, and Air Serbia and El Al maintain smaller Russia-facing networks.

That divide matters for brokers and underwriters with exposure outside the traditional Western fleet base. The European Union Aviation Safety Agency already maintains a conflict-zone bulletin flagging Russian airspace as high risk for civil aviation, citing the danger of aircraft being caught up in Russian air-defence responses to Ukrainian strikes - a warning that predates Zelenskyy's comments but that his statement now sharpens considerably.

Aviation risk advisory firm Osprey Flight Solutions echoed that concern in a client alert issued the same day, telling airline and insurance clients that daily Ukrainian strikes deep inside Russian territory, including near Moscow and St Petersburg, were "near-certain" through the rest of 2026, and that the risk of misidentification of civilian aircraft by Russian air defences was a live one. That kind of third-party risk assessment is precisely the input underwriters lean on when deciding whether to keep quoting cover for a route, tighten wording, or walk away from it altogether.

Pricing an escalating, moving risk

Aviation war underwriters have spent the past four years learning to price political risk that shifts by the week rather than the year - lessons drawn from the 2022 seizures, and more recently from disruption linked to the Iran-Israel conflict, which saw hull war rates climb sharply and forced widespread rerouting away from Gulf airspace.

The parallel is instructive but imperfect. The 2022 crisis was fundamentally about trapped assets - aircraft that couldn't be recovered once grounded. What Zelenskyy is describing now is closer to live airspace denial: a war-risk scenario where the danger isn't a seizure on the ground but an incident in the air, with drones from both sides now flying at a scale that air-defence systems on either border may struggle to distinguish from a threat worth shooting at.

For brokers advising clients that still route through Russian territory - largely a non-Western client base at this point - the risk profile now includes a public statement from Ukraine's own president, and a matching risk-advisory alert that the threat profile has materially changed, on top of an already-hardened market for hull war capacity.

The likely near-term result is closer scrutiny of policy wording on Russian and Belarusian overflight at the next renewal cycle, rather than a sudden mass withdrawal of cover - insurers moved the same way, gradually rather than abruptly, when Gulf airspace risk spiked earlier this year. Whether that scrutiny hardens into tighter exclusions or steeper premiums will depend on how the drone campaign develops through the autumn.
