Airline Tycoon First Class is what I would recommend. There are some tedious things in it, such as being sabotaged by other airlines, etc etc. Thankfully, when playing in "free game mode" if you're savvy, you can get rid of the other competitors (liquidate through buyout, sabotage them till their image reaches -90%, and poof, they disappear).
The stats for the aircraft in the game pretty much only reflect charter set ups for each aircraft. Also, not all aircraft are in the game, but MANY are. Some strange things include
777-300, but no 200
757-300, but no 200
737-400/800, but no others
MD-81, no others
A320, A310, A300, no others.
the game is TONS of fun. but again it has its flaws... Some of the fuel efficiency is strange (I don't think a 727 burns more fuel/hour than an A300, a 767, a 744, or a 777)
