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
