I took a trip to Japan by Aeroflot late in 1993, after the Soviet Union had fallen. By then, the flight from London to Tokyo was often operated by their shiny new Airbus A310, so it was too risky to make a booking to Narita hoping for an Ilyushin and ending up flying the Airbus.
Aeroflot still flew to Nagoya, so we chose NGO (the original Komaki airport) as our destination and were rewarded with a 9 hour trip by IL-62M.
I recall there were about 18 passengers, so we were all moved to the front of the plane to make the "service" easier for the crew, or weight and balance.
The business class seats were standard economy seats but with extra leg room. Eating the the meal was challenging, as the seat back tray table was too far away for comfort. Chicken, peas and rice was still the standard Aeroflot meal back then.
We were the only non Russian/Japanese on the flight, so Japanese Customs took an interest in our luggage on arrival.
