In SFO lounge now. CX 879 is delayed an hour so we are told at check in.

Does CX overnight its plane at SFO for the 879 morning departure? If so, what might be the reason for the delay?

We are told that the arrival time would only be 25 minutes late at 7:05PM - yeah I will believe it when we actually depart at 1PM and do not need a tech stop.
