Airlines barred from or avoiding Russian airspace burn 13.8% more fuel per flight on Europe-Northeast Asia routes than rivals that still overfly Russia. The analysis, comparing identical routes and aircraft types from March 2025 to June 2026, estimates the extra burn adds 1.53 million metric tons of CO2 a year.
Why it matters
Rerouting around Russian airspace lengthens flights and raises fuel use, turning a geopolitical airspace closure into a measurable emissions cost for carriers and the planet. Finnair, which is not planning for the airspace to reopen soon, has seen its company-level gross CO2 emissions rise roughly 10% since 2019.
The analysis compares identical routes and aircraft types in 2019 and from March 2025 to June 2026, showing a 13.8% fuel-burn penalty for carriers avoiding Russian airspace. Jet fuel currently costs $4.59 per gallon, but the source does not quantify how the extra burn translates into added operating costs for airlines.
The players
Finnair
Finland's national flag carrier, whose Northeast Asia flights are among those measured as longer and more fuel-intensive after rerouting around Russian airspace.
Emirates
The Dubai-based airline that recently launched a Helsinki connection, part of carriers adding European links that rely on Russian airspace.
The details
Russia closed its airspace to EU and UK carriers nearly four years ago, and British Airways suspended London-Beijing service in 2024 while Virgin Atlantic dropped Shanghai service the same year. Carriers still using Russian airspace are adding European connections, including Emirates' recent launch of Helsinki.
Timeline
2019: Baseline year for the fuel-burn and emissions comparison.
2024: British Airways and Virgin Atlantic dropped their Beijing and Shanghai routes.
March 2025 to June 2026: Period of fuel-burn data analyzed for the comparison.
Big Picture
Russia closed its airspace to EU and UK carriers in 2022, forcing European airlines onto longer Northeast Asia routes. The new fuel-burn analysis measures that rerouting penalty directly, showing the closure's effects have become a lasting emissions cost rather than a temporary disruption.
Travelers booking flights between Europe and Northeast Asia may see longer itineraries on carriers that avoid Russian airspace, with routes through Helsinki or other European hubs becoming more common. Comparing total journey times rather than just fares can help when choosing among connecting options.
The takeaway
Routing around closed airspace adds real fuel and emissions costs that show up in airline operations long after the initial closure. Travelers comparing options should weigh total flight duration alongside price.
