I just saw something interesting and can't seem to get any more details.

I logged onto the GM Card's web site to check my balances (and GM earnings) on my credit card and saw this: It then says to click on the logos for more information, but it doesn't work.

So, anybody know some more details on this? Looks promising!

I emailed GM Card this morning and have already gotten a response back on this. Here is the scoop on American Airlines and Marriott:

Thanks much for all the info Steve. Too bad they aren't a little more generous with the awards or offer equal discounts for more lower level options. My wife and I have never had a $90 joint meal (or even half that!), so using $25 in awards to get that and similar "discounts." aren't especially appealing, especially since you'd probably need to go through GM for bookings, which may not give the best rates.
