Some new Suggestions

I like your ideas about the service profile and low cost, Luxury airlines and this would be an interesting addition to the already super realistic game.

I don’t think the ideas about pilots will have much difference on your holding because it will not matter that much. Anyway it will mean a hell of a lot more work for the developers and would’nt neccessary yield benficial results.

The idea about passenger handling is already being used, on all airports you have standard AS handling but if you look on certain airports under "ground services" there are alternitive options for handling
