extra features?

An efficiency penalty for multiple aircraft types. I get that there is a maintenance penalty, but the impact on logistics across the airline is much larger in real life and should have a bigger impact, which would make choosing aircraft types more interesting, especially when we're talking 10+ types

Seems interesting. Can you elaborate a bit? We do have a fixed family maintenance cost but I'm curious as to what the other costs/impacts would be for operating multiple aircraft families.

I don't work in the industry, I just like planes, so I'm not familiar with some of the more detailed aspects of airline management.
