I can’t find ANA & JP EXPRESS (AJV), a cargo carrier owned by ANA, Japan Post, and Nippon Express. They fly B763’s cargo conversions from RJGG, to PANC to KORD, flight #8478, and flight #8479 on the return trip. They have a separate ICAO code from ANA.
Thanks. So it appears the airline needs to be added to the database, since the flights return “unknown owner”.
