The aircraft is heading 81.91° at 440 kt, and the only ALIGNED candidate (Δhdg ≤ 25°) is LIRA at Δhdg 26°, just outside the strict 25° threshold. KBOS has Δhdg 32°, also close but not aligned; however, KBOS is a recent destination (2026-06-25) and the plane's track points generally east-northeast toward New England. KHPN is home base but Δhdg 37° and behind the current heading. No candidate is perfectly aligned, so confidence is moderate; KBOS is the best plausible match given recent history and direction.
