Verizon

The plane is at low altitude just west of Chicago, heading 270° at 129 kt — likely climbing out. The candidate table shows KSFO is strongly ALIGNED (Δhdg 3°) at 1576 nm, which is within the G550's range and is a recurring destination for Verizon. KARR (Aurora) is also ALIGNED but very close (0 nm) and the plane is not descending, making it less likely as a final destination. Past predictions for this subject have been wrong 6 of 7 times, often over-predicting KEWR/KAUS, but here the geometry and recurring destination converge cleanly.
