Status bonus has been hit or miss. A few data points:

Sept 17: YEG-YVR-HKG all legs posted after a couple of days with CoS and SE bonuses.

Sept 22: HKG-YVR-YEG - the HKG-YVR leg posted correctly by the time I was in the lounge with the CoS and SE bonus, the YVR-YEG leg only included the CoS bonus (missing SE bonus). Posted by the time I woke up the next morning.

Sept 24: YEG-YVR posted immediately with CoS but again missing SE bonus.

Sept 25: currently taking odds on whether my YVR-YEG on AC250 posts correctly.

edited to add:

less than an hour the flight from tonight posted correctly. The only thing I can think of was my eUpgrade yesterday cleared at the gate while tonight’s had cleared 14 days prior. That doesn’t explain Mondays flight which was booked in J though.
