Applying Logical Knowledge

Exercises

Implement the commands for CourseAir, testing each and debugging as you go:

show_passengers(FLIGHT) - A list of passenger names and addresses on the flight.
show_passengers(FROM, TO) - The same, but starting with FROM, TO
show_flights(FROM, TO) - Show direct flights and two hop connections between FROM, TO
Add price to the above report - $10 per distance unit (DU), connections are sum of price for legs.
Add more complex pricing rules based on distance, carrier, aircraft type, special fares, such as:
- delta costs more per distance unit (DU)
- 767s are more expensive than 727s
- flights over 20 DUs requires a $100 surcharge (maybe depends on plane type)
- delta flights from CVG cost 50% more
- united flights from DEN cost 40% more
- flights from LAX are 50% off
look_for_mayhem - The Roger Rabbit evil doers want to stop toon mayhem on flights - they suspect it occurs when either 2 toonsville residents or 2 ducks are on the same flight. Show these potential trouble flights.
