Is anyone else is still waiting for theirs to post. I had closed the out the end of the year crossing another mileage boost threshold, but when my statement cut I didn't see the mileage boost. I called Amex and they told me my spend was $22k off of the 3rd mileage boost (email offer from March 2018). I questioned the rep but she then corrected herself and said yes your account shows you qualified, but it will take 10-12 weeks for the miles to post. This is not consistent with other mileage boost thresholds I've received in the past as they always show up on that months statement.
