Not everyone is an elite in AA; myself included, so no elite bonus for me -- and no special dines, either, then.
United provides the same bonus on a pro rata basis whether you were elite or not, so an elite in the United dining program is rewarded with some extra miles over the non-elties by virtue of their status with them last year -- this is fair -- the AA scheme punishes AA dining elites, that is not fair.
Until AA dining rewards me at least as well as its non-elites, my wallet is staying shut to them!
Bottom line, under the United promotion I eke out 10 miles to the $1 -- acceptable but nothing to write home about.
Under the AAdvantage dining program, I do not. It is that simple.
