Data points
1) Award Wallet- make a comment on their blog and get a few points.
I posted on 1/8/2018 just after midnight.
Got the email that I got the points on 1/9/2018- it said the points were awarded on 1/7/2018. They're probably not Eastern time. AA has them posting on 1/8/2018.
2) I used the AA portal and made a purchase on 1/8/2018. It hasn't posted yet.
Edit: I checked the wrong account. The points for the purchase have posted. Dated 1/8/2018.
2) I made an award booking on 1/7/2018 and cancelled within 24 hours.
The booking show in the 'activity'.
But both the points and the taxes haven't been returned yet. Officially can take up to 2 weeks.
