Yeah, the point is he got miles and sectors for a flight he didn't fly. Now that's a bonus which could be confiscated if it was flagged up to CX.

If I were him I would just keep quiet with a smile. Just hope that CX won't catch this error in the future and remove the miles, something which has happened to people on this board before according to a few posts. If the guy is frugal with Asia Miles maybe he should spend it on an award as soon as possible before CX spots the mistake and attempt to remove the points from his account.
