10 days ago I placed the following charges on my newly received AAdvantage cards, having confirmed the 50,000 miles/$150 statement credit offer (after first AA purchase) was on the account when activating each account:

AA Visa:
$50 AA giftcard

AA Amex:
$50 AA giftcard
$25 AA award ticketing fee
$7.50 AA award taxes

10 days after placing these charges, I still haven't received any sort of statement credit on either account.

How low does it usually take for these statement credits to post?
