When booking BA tickets with Avios, on the payment page, the third line "Is the payment card holder travelling on this booking?" select No. Then, once ticketed, go to AA.com>Plan Travel>My Trips>Find Reservation (use flight #, date and departure city) then add your advantage number to that reservation.When doing it this way I haven't had a problem with AA not recognizing my status and I assume it would be the same for free bags from Citi AA cc.
Will try that next time, thanks.
NP.FYI, LGA has added precheck in Terminal B concourse C, the concourse AA flies to YYZ.
When? I flew out in Chol Hamoed and wasn't PreCheck then
