I would hope sooner rather than later as it's to be expected that AS flyers who have reserved booking combined AA/US itins would begin to do so for flights after the announced full integration date.

The obvious question is whether AS will continue to offer credit for all AA marketed/operated flights post-10/17 or whether the relationship will change ins some way. I'd lean toward the former (given the DL travails), but don't have the insider's knowledge to offer anything more than speculation.
