Yes, for long-distance, medium capacity flights the Il-62 is perfect at this time of the game (early 70's) - it is also quite a slick & beautiful plane too.
Surprisingly, the aircraft I have made the most profits with for flights between Europe and Africa is the Concorde. Distances are far, and passenger numbers are very low, yet with the Concorde's speed and range, I can fly from Paris to Mali, Burkina Faso, Sierra Leone, Ghana, etc etc, and make profits of over 500,000 € per aircraft!
This allows me to connect Africa with the world, and not let it remain an entirely deserted continent.
