Said it before and will say it again. The good old days of FF programs is over. With the inflation of instant status by getting just about any credit card, fewer flights overall, ridiculous bonus miles offers, route shrinkage, consolidation and other factors, this ain't like it used to be.
I still can work some good deals but unless you reach the highest tiers, FF status is just about only good for free baggage check.
Not matter AA, DL, BA, UA or whoever the race to the bottom is almost over and the result is going to be a tie. AA was behind into the race to the bottom (by that I mean superior to most) but will close the gap. Economics demands it.
Use your miles as fast as you can while they are still worth something
Cheers
