Moskovia Airlines, operating under the IATA code 3R and ICAO code GAI, was a Russian regional airline based in Moscow. It operated under the callsign GROMOV AIRLINE, a name honoring the legendary Soviet test pilot Mikhail Gromov, reflecting its connection to the Gromov Flight Research Institute at Zhukovsky Airport. The airline primarily served domestic Russian routes and select international destinations, functioning as a mid-sized carrier in a competitive Russian aviation market. It operated from Zhukovsky Airport (also known as Ramenskoye), located southeast of Moscow. Moskovia Airlines faced significant financial difficulties in the early 2010s, which led to the suspension of its operations. The airline ceased flying around 2012-2013, leaving behind a legacy tied to the historic Gromov aviation tradition in Russia.
