Prince Alwaleed bin Talal

The aircraft is currently at 37,000 ft heading 94° with 514 kt ground speed, and the only Aligned candidate (Δhdg ≤ 25°) in the table is OERK, which is the home base and lies directly ahead with a Δhdg of only 3°. All other frequent destinations (LFPB, LSGG, EGLL, etc.) have Δhdg > 130°, placing them behind the aircraft, and they are rejected by the geometry rules. The plane is clearly on a direct return leg to Riyadh from its recent Basel operations, and the briefing notes 'Home base: OERK'. Past prediction for this subject was incorrect (guessed OERK but actual was LFSB), but that was for a European departure; now the geometry strongly supports a return home, so I correct toward the aligned route. Confidence is high because the alignment is near-perfect, the distance is plausible for a cruise leg, and the destination is the owner's home airport.
