PNR will have been recycled by now I fear.
Looks like the only way is to ask them to reissue this at 15$ each.

2? Not familiar enough with the BA boarding pass buf if it has the BA record locator you can call them up and have them find the AA record locator in the BA record. Then you can gpo to an AA ticket counter.
or if you have the ticket number from your AX what happens when you enter that number into the AA refund web page to get a receipt or record locator?
