Carlos Slim

The aircraft is heading 103.95° and Cancún (MMUN) is at bearing 83° with Δhdg 20°, making it the best ALIGNED candidate. Cancún is a recurring destination for Carlos Slim, and the 775 nm distance is well within the G650's range at current speed. Past predictions show a tendency to guess home (MMTO) when wrong, but the current track clearly points east-southeast, not toward Toluca (bearing 128°). SBGR is also ALIGNED (Δhdg 23°) but at 4108 nm is a very long leg, less likely for a routine flight.
