MGM Resorts

The aircraft is at 38,000 ft heading 305.6°, and KLAS is the only ALIGNED candidate (Δhdg 20°, 482 nm). KLAS is the home base for MGM Resorts, and the plane's recent flights show frequent returns to KLAS from various California airports. Past predictions for this person have been wrong when guessing non-aligned destinations (e.g., KMIA, KLAX), so I bias toward the aligned home base. The distance is well within the Legacy 500's range, and the heading points directly toward Las Vegas.
