I'm trying to design my screen layout and I'm having trouble deciding what should be used as selection criteria fields. Obviously, there should be selections based on flight number, origin and destination airports, carrier and day, but should there also be selections for the other fields like price, time, duration, and current number of available seats?
Also, are some of my obvious choises not so obvious?
In addition, should I make cascading selection boxes (if they pick an origin of 'SFO' it automatically reduces the selections in other boxes to only those still valid)
