Aeroflot may be partly stripped of its prized overflight royalties under a proposal submitted to the government by the Federal Anti-Monopoly Service, Interfax reported Tuesday.

Citing the deputy head of the anti-monopoly watchdog, Anatoly Golomolzin, the agency said the goal of the proposal was to redistribute the royalties, which analysts value at about $300 million per year, among various Russian airlines.

"Anti-monopoly officials do not have the authority to take away the royalties completely. Our aim is to ensure a level playing field for Russian aviation firms," Golomolzin told Interfax. He added that his agency's proposal had been submitted in a letter to Prime Minister Vladimir Putin's government.

Former Aeroflot CEO Valery Okulov, who had run the airline for more than a decade, had been critical of the government's newly created carrier, Russian Airlines, which he called a "pyramid scheme."

Analysts have said part of the motivation for creating Russian Airlines was for the state to get closer control of the royalties.

Russian Airlines is a unit of Russian Technologies, an industrial conglomerate wholly owned by the state and run by Putin's close ally Sergei Chemezov.

It was created in November last year, mainly by combining about a dozen airlines bankrupted by the financial crisis.
