I had a very long conversation with American the other night. Some markets are being blocked (i.e. you cant get tickets). For example, JFK-San Juan (non-stop) cannot be purchased for my travel -- 12/28 - 1/4. We are at the whim of Yield Management.
There are other markets that are blocked also -- Vegas, Denver, Orlando (and most of Florida) and a few other locations -- but not all.
Fares are about the same as usualy (or so I am told) -- $672 r/t for JFK-San Juan (Funny -- they could quote me an approximate price but not get me my tickets). They said by the end of April I would be contacted by AA about purchasing tickets.
Of course, waiting has cost me some $$$. Fares on Tower Air (I know, Tower), started in January at $350 and are nor at $550. Loyalty has cost me $400 so far.
