Has Amex changed their MR posting times? I have always received my signup bonus points very soon after reaching the minimum spend. When I contacted them they indicate that it is 8-10 weeks from date of reaching the minimum spend. Sure enough when I found the fine print it does indicate this (except it says up to eight weeks):

Please allow up to eight weeks for the Welcome Bonus to be awarded.

For some reason, it says only six weeks for the Plat card.

I sure hope it doesn't take this long as it will change my timing for churns, especially when I want to use these for the Avios bonus (hopefully coming).
