Hello I have seen some aircraft registration number is not correct. Air China 747-8 registration number is B-2443. Planespotters and AirFleets.net say it’s a 747-400 and that plane is scrapped. All Air China 747-8 numbers are between B-2479and B-2487. B-2479 is VIP
This is a known issue. It might not be top priority given how old this aircraft is though.
FlightGT had this documented internally and will track there. Thanks GT and AeroPlane!
