Generally speaking, the passenger list and related information, including ID number and seat number, are usually only provided to airline managers and ground crew. This information will be used for procedures such as transfer, security check and boarding.
However, in some cases, if there are important people or special needs on the plane, the passenger list and related information may be sent to the captain's cab display screen. In this way, the captain can know the passenger's seat allocation, emergency contacts, special requirements and other related information to ensure the smooth and safe flight. But this is not the general situation.
If you have any questions about the passenger information of the current flight, I suggest you contact the airline customer service directly for consultation.
