Current heading 71.04° aligns strongly with KTEB at Δhdg 8°, the only ALIGNED candidate. KTEB is the subject's home base, and after recent California flights (e.g., KVNY to KSJC), the eastbound trajectory over the Rockies at 41,000 ft and 547 kt suggests return to Teterboro. Past predictions missed short SoCal-NorCal hops, but this 1486 nm leg fits a direct homeward cruise on the G650ER, consistent with briefing's NorCal-SoCal to East Coast pattern.
