This aircraft hasn't always been like this. Produced in 1998, it belonged to the American 'Continental' and carried simple American citizens when the Russian air company 'Transaero' purchased it to turn into a luxury plane.
The plane is divided into four parts: economy class, premium class, business class and first class (if we compare it with regular planes). Apart from big comfortable leather seats, TVs, telephones, wall outlets, it has a large leather sofa and is equipped with WiFi. No golden lavatory bowls or emerald incrustations were found which is good.
Nevertheless, its rent is going to cost like several thousand dollars an hour, so no mere mortal will likely to ever experience the comfort of flying by it.
So, check out the photos.
