Can someone tell what CO9990 is; is it a test flight # or something else?
I see it takes off from various fields then lands back at the same one sometimes another one! :astonished:


The 9990 in CO9990 denotes most likely a maintainance flight by the airline. Check out the flight history and you will see different equipment and location. Most of which have a single dept. and arr. airport.


Thank you very much lancasterperch for that info! :smiley:
