Airline Club

Well - maybe you can modell this like the rl? A Slotlimit is very important for balancing.

- everyone who like can buy availiable slots. Could be automatic within creating a route
- If an airline going bancrott - there will be a lottery. Airlines can apply and they get the slots after certain criteria (new routes which current no other supply) and so on.
- Unused slots  (<80% usage) will release after a certain time to the public pool

Btw. Slottradingsystems will be great - but are very susceptible for cheating.
