I have never had trouble using my AA miles. I am a avid FlyerTalk reader of course. I do not see the basis for the whining because if one just did a little research, used a little savvy and applied some energy in the process, you will find AA has one of the best reputations for award redemptions.
The last full award was an AA All Partner Award where I was able to fly Business/First on AA metal SCL-MIA-LAX then on LAN's newly outfitted business 767 non-stop LAX-SCL (no LIma stop crap here)
Three times before that, I easily used my miles to upgrade to domestic first/international business from the States back to Chile (I prefer upgrades RETURNING TO CHILE

).
As an AA Gold, I have had a nearly 90% success on using my accrued domestic upgrades on segments like DCA-ORD-LAX, MIA-DCA, DCA-MIA, though on LAX-DFW only about 50%.
The AA hub-MIA/DFW-SCL routes are not that hard to score upgrades compared to other destinations.
And I will always remember the same-day, immediate availability for a SCL-MIA-LAX award to get me home ASAP after my father died.
Just a SPAM KILLER. You are on your own in this forum. My personal mission here is done.
