Please help! I have a reservation for CX#873 SFO-HKG. The tickets are for my senior-citizen parents and I don't want to confuse them unnecessarily, although I am confused already.

Here's the schedule as listed on AA's site:

CX#873 - Depart SFO - April 29, 12:45am
Arrive HKG - April 30, 6:35am

Same flight is listed on Cathy Pacific site:

CX#873 - Depart SFO - April 29, 00:45
- Arrive HKG - 06.35+1

Flight time is 14:50 hours.

So the question is, are they actually departing around midnight of April 28, and then arriving on April 30?

I would really appreciate it if anyone can clear this confusion up. If anyone has flight experience with CX#873, please also post. Thank you.
