I had the same dilemma this year, but being in DFW, it’s really hard to not do AA. But when I can get cheap AS fares on longer flights in first class, I’ve cleaned up nicely in taking the credit as AA LPs. Less than 2K spend this year has already earned me 30K LPs vs less than 18K if flown on AA metal. The free lounge access with paid AS first class is a nice perk, too.
