One of the reasons we have the Flight Kiosk was the fact that many of the airlines do not publish their schedules so we can upload them into our schedules. We now have a system where you can enter in a flight by the airline and flight number and have the most up-to-date flights available. Even if the flight is not being flown at the present time you can still request it and someone from the Schedule Division will review and approve it, as long as after researching it is found to be a valid flight. The only restrictions are it must be found on one of the flight look-up sites and an airline with a valid IATA or ICAO code.
Another way to search for flights utilizing a particular type aircraft is to go to the FlightAware site and go to "Live Flight Tracking" and
"Browse By Aircraft"Remember though, when choosing a flight it must be one flown as a scheduled flight. There must be a recognizable ICAO or IATA code preceding the flight number. No aircraft or flights with "N" numbers. These are GA flights.
Hope this helps. HAVE FUN!
