I've just early qualified for AC Elite, finished my selections and am awaiting my package. I have a reasonable amount of transborder travel on US and UA upcoming and I am wondering whether they will know if I am *G. Does status pass at the time of booking, check in or another time..

Just wondering because without the status on the record I'd have to pay for bags until my card arrives. And no priority boarding, which is a big deal on the US YEG-PHX flight..
