If I keep traveling as often as I am these days I may end up keeping the Platinum assuming the $200 Airline incidental credit keeps working for AA GC. I have a Centurion lounge at my home airport. (AC, too as it is an AA Hub)
I already get checked bag from my Aviator, as well as Priority Access from booking awards flights with Avios instead of using my AA miles, which are strictly for long haul or otherwise point prohibitive with Avios (FC awards are 4x point cost as Econ vs 3X for Biz, 2x PEcon)
Using my first 100K MR was a breeze with 82K 1:1 going to BA, 18/6K to Starwood to top off for a 20/25K to AA.
Add to that the fact that I was able to book a $500 RT with 15K Avios, (Which shot up to $950 2 weeks before flight). I'd say i'm doing just peachy and could afford to keep it quite easily especially if I keep getting those kinds of redemptions. Before anyone asks, Yes. I would have paid that ($500) for the flight if I had no other way.
