Airline Tycoon, better known as Airline Tycoon First Class in-game, is an updated re-release of Airline Tycoon. The subtitle was dropped in the manual and on the covers because this was the first game in the series released in US and UK territory.
The most significant new features are cargo flight assignments, a completely new campaign which consists of 10 new missions and finally a multiplayer mode. Minor novelties include changing seasons outside the airport, new MIDI music, more aircraft upgrade capabilities (besides enhancing passenger comfort as in the original, one can also improve steering, safety etc.), new items and slightly improved briefings.
