24 June 1932 is considered to be the birthday of Pulkovo Airlines. It was on that day that its first facility, the Shosseynaya airfield was commissioned, with the first two airplanes with passengers and mail from Moscow landing on its ground. By 1941 Moscow-Leningrad became a regular passenger line, previously being a mail/passenger line. After the war, operations started in January 1948. In January 1963 all sub-units of Leningrad’s airmen were united into Leningrad United Air Unit. By the order of the Director, Air Transport Dept. of the RF Ministry of Transport, the Leningrad United Air Unit was renamed Pulkovo Airlines in 1992.

The airline Rossiya was established in 1992, wholly owned by the Russian government. In early 2000's the Russian government decided to merge Rossiya Airlines with Pulkovo Airlines. The merger process began in December 2004. In November 2006 it was announced that the merger had been completed and Rossiya Airlines was registered in Saint Petersburg on 9 October 2006 and has a branch in Moscow and 54 offices in Russia and abroad.

In February 2010, the Russian government announced that all regional airlines owned by the state through the holding company Rostec would be consolidated with the national carrier Aeroflot in order to increase the airlines' financial viability. On 28 January 2011 "Rossiya Аirlines" open joint stock company was established in St.Petersburg. The airline has operated flights under Aeroflot's ICAO code designation "SUxxxx" since 30 March 2014.
