Citigroup

KIAD is the only ALIGNED candidate (Δhdg 7°) and a recurring destination for Citigroup. The aircraft just departed KTEB (home base) and is heading 228°, nearly directly toward KIAD (bearing 235°). Past prediction error (guessed VHHH when actual was KTEB) reinforces not to guess far airports; current geometry strongly supports KIAD. Distance 194 nm is plausible for a short leg. Confidence is high because the ALIGNED candidate matches both geometry and prior pattern.
