Call Air China customer service, ask him, tell the date and flight number of the day you did it, and ask who the pilot is. But you are sure to fail. You can't know about it. The mission plan may change. Before carrying out the task, the captain should arrive at his post 90 minutes before the flight takes off and stand by, and the international flight 150 minutes. The captain who is preparing to leave Hong Kong will wait and prepare the flight in the back flight room arranged by the airport companies. But as for who the captain is, if he has a long speech on the flight, he will announce his name first. If he doesn't talk, you won't find it, and the customer service doesn't know about it. This is all arranged directly by the company, and there is also the possibility of temporary changes.
