Thanks for the replies, guys. It seems like there is hard to find info regarding this flight. I am trying to prove to my Insurance carrier that this flight was delayed, but even China Southern Airlines do not have the proper documentation.

If someone has a suggestion for what to do, it would be greatly appreciated.

To the last poster; it seems like I need a paid Subscription to Access data older than from this year. If anyone has such a Subscription, I would appreciate it greatly if said person could check for me.
