Ok, so you started a airline, and don't know what to do? First, if you start in world A, you'll have 5 million but in world B you'll only have 1 million. Usually
at start you should buy a AN-2. It's the only plane you can afford if you play World B. But if you starts with World A you can also buy AN-26 which can
carry more passengers(If you join later, you'll have more plane which is bigger that you can afford too).
Then, you should have some new routes. Click into the "Market Research" tab. Choose a route that is not longer than the distance your plane can fly. Note
that your origin must be in your country. Otherwise you'll see a message telling you "You cannot operate this flight due to political restrictions!". Then click into the
flight planner. Your plane have to be back to where it start before next day or you'll see another error "Discontinuity in Aircraft Schedule." Also keep an eye on
your plane's "turnover time". It's the time that the plane prepares for its next flight. Then, click "save" and wait for a while. After it shows "Success!" close the flight
manager tab. Wait... you're losing money? You should change the price. It's default is $100 and you should try another new price that you can earn money but people
doesn't feel so expensive.
Great! You've created your first route! Now wait for the money to roll in!
