Russia airspace closure lifts emissions for Europe‑Asia flights
Russia’s continued closure of its airspace to EU and UK airlines lengthens Europe‑Northeast Asia flights, increasing fuel burn and emissions. The ban has been in effect since 2022 and impacts carriers such as Finnair, raising travel times by roughly a third and adding 1.53 million tonnes of CO₂ each year.

At a glance
- What changes
- EU and UK airlines must avoid Russian airspace, lengthening Europe‑Northeast Asia flights
- Timing
- Closure has been in effect since 2022
- Who is affected
- Passengers on EU and UK flights to Northeast Asia
The details
- Takes effect
- 2022
- Previous rule
- Before 2022, EU and UK carriers could fly directly over Russian airspace on routes between Europe and Northeast Asia, using the most efficient paths.
- New rule
- Since the 2022 ban, those carriers must detour around Russian territory, resulting in longer flight distances and higher fuel consumption.
Background of the airspace ban
Russia barred airlines from EU countries and the United Kingdom from its airspace as retaliation for Western bans on Russian carriers after the 2022 invasion of Ukraine. The restriction remains in place, forcing affected airlines to reroute around Russian territory for all Europe‑Northeast Asia services.
Operational impact on routes
Finnair reports that its flights to Northeast Asia now take about a third longer than before the ban. Analysis by Skailark shows carriers forced to avoid Russian airspace burn 13.8% more fuel per flight than rivals that can still overfly Russia. The study compared identical routes and aircraft types from 2019 with data collected between March 2025 and June 2026.
- Longer routes add roughly 33% more flight time
- Fuel burn rises by 13.8% per flight for barred carriers
Environmental consequences
The additional fuel consumption translates into about 1.53 million metric tons of carbon dioxide emissions each year, representing roughly 12% of total emissions from Europe‑Northeast Asia flights. The increase undermines airlines’ climate goals and adds a notable greenhouse‑gas footprint to a segment that already faces high environmental scrutiny.
What this means for travellers
Trip planning
- Travelers on EU or UK flights to Northeast Asia should expect travel times about one‑third longer than before 2022
- Flight schedules may show later arrivals; monitor airline communications for revised itineraries
Cost and documents
- No new fees or documentation are required because of the airspace closure
- Ticket prices could rise indirectly from higher fuel costs, but airlines have not announced specific surcharges
What you need to do
- Watch airline updates for any schedule adjustments caused by longer routes
- Consider alternative carriers that still fly over Russian airspace if available, though options are limited

Frequently asked questions
Why are flights from Europe to Northeast Asia taking longer?
Because Russia has barred EU and UK airlines from its airspace since 2022, forcing carriers to fly longer detours around the country, which adds roughly a third to the travel time.
How much more fuel do airlines burn because of the Russian airspace ban?
Airlines that avoid Russian airspace burn about 13.8% more fuel per flight than carriers that can still overfly Russia, according to Skailark’s analysis of routes between March 2025 and June 2026.
What is the additional CO₂ emission caused by the longer routes?
The extra fuel burn adds approximately 1.53 million metric tons of CO₂ each year, which is about 12% of total emissions from Europe‑Northeast Asia flights.
Which airlines are most impacted by the airspace closure?
Finnair is highlighted as one of the most affected carriers, with its Northeast Asia flights now about a third longer than before the ban was imposed.
Will ticket prices increase because of the longer routes?
Airlines have not announced specific price changes, but higher fuel consumption could lead to higher fares; travelers should watch airline announcements for any fare adjustments.
Are there alternative routes that avoid the Russian airspace ban?
Some Asian carriers such as those from Japan, South Korea, and Taiwan already avoid Russian airspace for safety, but EU and UK airlines have no alternative but to take longer detours around Russia.
