Transaero acquired a small number of these aircraft from Singapore Airlines in late 2011 and has completely refitted them with its own four-class interior.
All the seat covers, overhead lockers and other soft furnishings have been replaced and there is a Lumexis in-flight entertainment system.
There are four first class, 14 business, 133 premium economy and 222 economy seats, making a total capacity of 373.
The 777-300s are used on long-haul domestic and international routes, mainly from Moscow to Vladivostock, Khabarovsk, Tel-Aviv and Dubai. It is planned to deploy them on flights to the USA in future.
