How can I find out a planes flight plans if I have the planes reg number?
The example you gave to track, an AIRLINE FLIGHT, is NOT trackable online via its registration on any site. You won’t find airline flights via their registrations as their flight plans are not filed under their ship numbers, only their flight numbers. ATC doesn’t even know what ship number the flight is when they track it. Only aircraft with plans filed under their N-numbers are trackable via such sites with a registration. In order to track the US Airways legacy commemorative paint schemes, you will actually have to know the flight numbers they are operating as at any given time. For general flight tracking, http://www.flightaware.com is the best.
