tracking line disappears


I have noticed on several flight trackings that the track line disappears before the aircraft reaches it’s destination. Why is that happening? Thank you.


One of the following.
1.ATC canceled radar services.
2.The Pilot canceled IFR.
3.Aircraft decended below Radar coverage.


Number three above is not correct.

See … r+coverage for Flight Awares handling of below or non radar environment.



A link to your flight would help.

One other possibility is that you are transferred from en route controller to local airport controller and your actual arrival notice is not transferred up to the FAA at the national level ( where FA gets all its data ) and thus your track falls off at the transfer point.
