Interesting. Thanks for the link. Just called the EXP desk. They said that there are seats available in all classes GRU-JFK tonight. Said that I had a good chance of clearing. Seems to me that the problem is on the AA side specifically its website (and how that links with google flights). To review: aa.com is not selling seats in any classes on 950 tonight, neither is google flights, EF shows availability, and the EXP desk said that there were still "several" seats in J available for sale. Your comment about the phone rep above confuses me. I hadn't previously talked to a phone rep.
