Type in the flight number for your flight all you and Flight Status returns the information for your flight. (Usually within 10-20 seconds.) If you do not know the flight number you may also fill in a small form and retrieve a list of flights for that airline.
The information it gives you is: Departure City, Arrival City, Departure Time,Arrival Time, as well as airspeed in knots, equipment and altitude. Some airports provide security check-point wait times. If available, they will be retrieved, too.
