Also check my experience on the Cubana Antonov 158:
Flying on one of Cubana’s Ilyushin Il-96-300 on a domestic leg from Cayo Coco to Havana. Flight CU 361 is a Cubana service from Buenos Aires to Havana with a short stop in Cayo Coco carrying mostly Argentinian tourists.
Cubana is the last civil operator of the Il-96 worldwide. This specific airframe - CU-T1717 - was acquired from Aeroflot in 2014 and entered service with Cubana a few months later. The aircraft is still wearing basic Aeroflot colours and the cabin interior remained in Aeroflot configuration.
