The island's national carrier has been expanding steadily over the past several months, and launched services to Shanghai last July, Guangzhou in January, and Kochi in March.
It plans to acquire at least six aircraft this year and has been increasing capacity throughout its global route network since last December as a post-war tourism boom gets underway.
Tourist arrivals from Russia grew by 21 percent in the first quarter of 2011.
The airline wants to cater to increasing travel to Asia by Russian tourists, especially to the neighbouring Maldive islands to which it operates six flights per day, and just over an hour’s flying time from Colombo.
