Carlos Slim

Current heading is 70° east-northeast, and LEMD lies at bearing 55° (Δhdg 16°, strongly aligned). At 45,000 ft and 497 kt, the aircraft is in cruise for a long-range leg. LEMD is a listed frequent destination for Carlos Slim. KJFK is the next aligned candidate (Δhdg 25°) but is slightly less aligned and a shorter leg; given the altitude and speed, a transatlantic flight to Europe is more likely. Past predictions for this person often guessed Mexican or US destinations and were wrong, so I bias toward the aligned European option.
