Introduce Customers that prefer Lower Prices and Customers that prefer Higher Reputation, make them each at most about 5-20% of any given Airport.
Reputation having a larger impact on Prices
If company A has 80% reputation
company B has 40% reputation
company B would need to lower their prices significantly to be able to compete, and even then they wouldn't get every passenger. They would be on equal footing.
IFS/IFE Reputation Affects Sales
No Minimal Sales. If an IFS/IFE is bad enough, then it will not sell.
Airplane Storage Requirements
Every Airplane you own must be stored, thus creating a new facility players must purchase to be able to expand. As well as punishing excessive spamming.
Storage will be based on Plane Size, since we don't want to make the game become just Huge Planes.
