On May 6, a widely circulated online post claimed that Air China flight CA929 triggered a "7500 squawk code" mid-flight, drawing public attention and speculation.
According to publicly available aviation codes, a transponder code of "7500" signifies unlawful interference—typically used to indicate a hijacking or the threat of one.
Flight tracking data from the app "VariFlight" indicated that flight CA929 issued a "7500 alert" at 11:55 a.m. on May 6. The flight was scheduled to depart from Shanghai Pudong International Airport Terminal 2 at 9:55 a.m. and arrive at Tokyo Narita Airport Terminal 1S at 2:00 p.m. local time. Records show that the aircraft took off at 10:12 a.m. and landed safely in Tokyo at 1:41 p.m. local time.
However, when reporters checked multiple flight information platforms around 1:00 p.m. that day, none showed any evidence of the flight transmitting a "7500" code.
At around 2:00 p.m., customer service staff at Air China told reporters they were unable to confirm whether the squawk code had been activated, but confirmed that the flight landed safely without incident.
A representative from VariFlight later clarified that the "7500 alert" was triggered due to a data anomaly and was issued in error. The issue is currently under review.
A passenger onboard flight CA929 also confirmed to reporters that the flight landed without any problems and that no unusual events occurred during the journey.
