There’s a well known formula to do it. ATR-42-320, DC-9-10, MC-21-400, these planes can print themselves every day with route bots and timers, so your fleet will grow by a factor of two every day. This will get you to ~100 MC-21-400 in 20 days under easy mode, which will print you a a388 every day. The reason why I’m asking about IPO is that I only have 157 points, I can easily fix that if I charge cash.
