I see now that you are correct. I found the page that breaks out all of the region-to-region charges for 1st, 2nd, 3rd, 4th bag, overweight and oversize. It's a very useful page that ought to be in the baggage wiki:
https://www.americanairlines.ie/i18n...es.jsp#baggage
However, this page and the other that was linked before both say that >70 lb. baggage is not accepted from Europe. Obviously this rule was not followed in this case. So, assuming $300 in overweight charges plus $150 in oversize charges for each bag per the page referenced here, that would be $600.
