I think it's time we keep a centralized repository of suggestions for new AE players. Feel free to add your own
My 3 main ones for a new airline (until you have > $100M in cash)
1) minimize the number of different aircraft families (keep to 1-2 families in the first few months)
- each additional family adds huge maintenance costs that are uneconomical if you only have 1-2 aircraft in the family
2) maximize flight hours (aircraft utilization), especially in the startup phase
3) spend cash to lease more aircraft and grow your revenue as quickly as possible
