One other mistake:

They list charges for third checked bags for F/J customers on travel outside the US. They also don't clearly indicate that fees do apply for 4th and later checked bags. Note that the actual baggage page (linked on this master table) does say that F/J pax are exempted from the 3rd bag fee on all flights.

I believe this is the first time that the complimentary overweight (to 70 lb) bags for F/J pax have been explicitly and clearly listed on AA.com.

Is there actually a link to this page on AA.com? I can't find it, and I also didn't see it included on any of the confirmation pages in a dummy booking.

ETA: Found it. Tiny type in the footer of every AA.com page that says "Optional charges". Even knowing it had to be there, that took me quite a while to find; the absence of the word "fee" is suboptimal, IMO.
