I have a couple that might be nice...How aboubt a "delete" or a "retire" function something to pull planes, routes, airports off of the availability list. How about something that (for smaller lines) includes days of the week that the route will fly?Also...Something that would allow you to keep track of the fleet,(tail numbers, how many, livery differences...) something that you could say I have X number of 767s, or A330s. What would be over the top is if you could assign a plane to a route, and it would keep track of how much availability remained, so you knew when you needed to "purchase" more A/C. And if you only intended to use 1 A340, you wouldn't assign enough flights to it that it could fill up availibility for three aircraft! Thanks for what you've done!
