The Russia–Ukraine conflict has significantly altered global air travel, forcing airlines to adjust to airspace restrictions, higher operational costs, and shifting passenger flows. This study examines how the closure of Russian and Ukrainian airspace has affected international flight routes, leading to longer travel times, increased flight-time costs, and changes in airline operations.
With 6.23% of global flights affected, many airlines have had to reroute around restricted zones, resulting in an average cost increase of 13.32%. Routes between Europe and Asia have been among the most impacted, with additional flight times extending up to 1.49 hours in some cases. For Japan and South Korea, which depend on direct transcontinental connections, the loss of access to Russian airspace has driven up flight-time costs. North American carriers, though affected, have managed to adapt with relatively smaller adjustments.
The effects of these changes vary across regions. While many countries have seen a reduction in air traffic, others (particularly those bordering Ukraine) have recorded increases due to the movement of refugees. Airports in Poland, Romania, and Slovakia experienced a rise in flight volumes, with traffic in countries neighboring Ukraine increasing by 25.6% in the first weeks of the war. These shifts in aviation activity reflect the evolving demands placed on airlines as they respond to new passenger patterns.
Russia has undergone the most dramatic changes. Total air travel costs have risen by 474.3 hours per week, with more than half of the country’s international flights either rerouted or canceled. Over a third of Russian airlines have ceased operations entirely, and many travelers now rely on transit through Turkey and Qatar. As sanctions continue to shape the country’s aviation industry, the prospect of regaining access to Western airspace remains uncertain.
The study highlights the far-reaching effects of geopolitical conflict on air travel. As airlines continue to adapt, governments and industry leaders will need to weigh the financial burden of extended flight routes against broader political and strategic goals. The long-term challenge lies in managing rising costs and shifting travel dynamics without permanently disrupting global air connectivity.
