MCT in Hong Kong (CX to AA)
Is this on one booking? If not I'd recommend calling each carrier to let them know about the connection. Especially if it's on one booking, CX will have someone at the top of the jet bridge when you arrive in HKG to guide you through connections, including cutting to the front of the security line. I've done this before with one-hour connections BA-CX and CX-BA and it works pretty well.
