I have tried Passenger 2 and Self loading cargo for the past two years. I was blown away when in June I found this free but with a premium path which I don't use. www.airopsfs.org What it is you fly, create routes, but ai pilots fly for you and you create codeshares, alliances with other players who fly the routes for their airline. so you are a flying CEO of your airline. It is similar to Flythe line but I don't really like flythe line personally. The unique touch about it is the fact you can fly multiple legs up to 4 I think, it plans the routes, generate the cabin crew voices ect. Very immersive. Although not available for Xplane yet.
