$1200 credited back to my account within a couple of days, without any prompting or reminding. Very good work Amex, thanks for the memories (and the long haul J award tickets).
Re: 80000 bonus point offer for new sign-ups: I've got to say it's a very good offer. No, it's not as good as it was when it cost $900 (when I signed up), but still, it is a big bucket of points at 1.5c per point. Then you get the $200 travel credit: ok so by the time you factor in Amex Travel's slightly inflated prices it's more like a $150 to $180 travel credit, but still. Also add in the Accor membership and the Plat Reserve (if they give you the Plat Reserve without a fight), both worth a couple of hundred bucks if used correctly, and you start to get an excellent package in the first year.
Renewing is not such a sweet deal, and probably not worth it unless you are wining and dining A LOT (ie corporate functions) or are too rich and lazy to switch cards. Maybe also if you are renting a lot of cars, and using it for the good car insurance cover.
