Still, on Friday evening, a couple hours before the big sale ended (1/16), AA.com would not price Sat-Sun turnarounds at the cheap price (it was pricing them at full Y), but it would price Fri-Sun trips cheaply. Other sites did price Sat-Sun trips at the sale prices.
I hope that this is not an indication that someone at AA is causing AA.com to refuse to recognize Sat-Sun trips as satisfying the rules. I prefer that the agents spreading the incorrect info not be in a position to enforce their incorrect interpretation of the rules.

There was a thread on this a few months back where the agent admitted it was an aa.com "issue" or something to that effect and that they were working on it.
I have searched and searched but can't find the thing...I'll keep trying as the response was interesting. Bottom line though was that you just had call an agent to purchase it and force the fare through
