On Friday, Korean Air announced it is canceling flights to Russia for the next two weeks, telling Reuters that it can no longer refuel in Moscow. Korean operates regular service between Moscow and Seoul once weekly on Thursdays, according to Cirium data.
Unlike airlines from countries in Europe and North America, Seoul-based Korean is not banned from flying in Russian airspace, but the carrier said sanctions against Russia may make it difficult to source jet fuel.
"We were informed by a Russia-based refueling service provider this afternoon that we can no longer refuel our planes at the airport in Moscow," a Korean Air spokesperson told Reuters.
The airline is also rerouting cargo flights to fly directly between Seoul and destinations in Europe instead of stopping in Moscow for fuel. The new routing will force Korean to carry less cargo in exchange for more fuel to make the nonstop journey.
Korean is not the only airline impacted by Russia's possible lack of oil. According to South Korea's national newspaper, Korea JoongAng Daily, Seoul-based Asiana Airlines will also stop fueling in Moscow on its daily cargo flights to Frankfurt and London.
