I hope that's not what's causing the error upon attempt to purchase, though. I assumed it's an issue of whether the actual inventory is available on the JL flight. The error is coming after pricing and after entering credit card info, after clicking purchase (and has happened to me before too). I would have assumed that aa.com is smart enough to apply fare rules before pricing. Maybe not?
