International passenger flights, with the exception of those bringing Russian home from abroad, have all been suspended, leaving airlines looking for alternative ways to make money.

Domestic flights within Russia have continued to operate, but demand for them has also sharply fallen.

State carrier Aeroflot and it's unit, Rossiya Airlines, have been included on the list, along with Ural Airlines, Nordwind Airlines, Azur Air, Ikar and Royal Flight. The list could be added to, Rosaviatsiya said.

Last week, President Vladimir Putin pledged more than 23 billion roubles (249.92 million pounds) in support to airlines, with Russia's citizens told to stay at home since the beginning of April in an attempt to slow the spread of the coronavirus.
