planecrashlaw, at the risk of going OT, i personally don't see anything wrong with CX rewards going 'cheaper' with AA miles. At best, annoying, if i think really hard about it- but i doubt.
+1 for a strong AA-CX relationship - i doubt CX is even remotely as close to any other OW member.
Its a free world, aint it

We all have our choices and no one's stopping another from moving to a different program.
Like, for most of us MPC elites, we traded away reasonable earn-burn rates and lack of fuel fines etc. to CX's (imho) outrageous levels and fuel fines, for our seat guarantees and more love from CX, knowingly.
BTW- i vaguely recall reading on the OW Forum a long while back, something about OW requiring that the same award availability be made available across OW carriers. Wonder how that plays out in real life (only ever redeemed for CX and 9W), especially with priority rewards and the like, and CX, in the past (and hopefully, soon again) releasing revenue seats for award redemption by CX DMs.
