Air China's silver card cannot be given priority security check. According to the policy of China International Airlines (Air China), passengers who hold Air China Silver Card members can enjoy certain benefits, such as extra free checked baggage and priority check-in. However, Air China's silver card does not clearly stipulate the privilege of bringing people into the security inspection area. Only passengers with valid air tickets can enter the security area. Therefore, Air China's silver card cannot be given priority security check.
