The story
The first rail link connected Moscow and Sheremetyevo Airport in 2002. In May 2008, Aeroexpress began to provide the rail link between Moscow and Vnukovo Airport (the line opened in August 2005). In July 2008, the company became the sole operator of rail links from Savyolovsky Rail Terminal (Butyrskaya Vokzal) and Belorussky Rail Terminal to Sheremetyevo airport and Lobnya, from Paveletsky Rail Terminal to Domodedovo airport, and from Kiyevsky Rail Terminal to Vnukovo airport.
In February 2012, the service on the first non-Moscow link, connecting Sochi with its airport, began operations, followed in late July by a similar link in Vladivostok and, in 2013, Kazan. On its Vladivostok route the company also offered a limited commuter service at discounted prices. Services on routes outside Moscow were handed to other companies in early 2015 due to heavy losses and the "current macroeconomic situation".
