Also I'm pretty sure if I book online it will be with LAN, but it sounds like AA is easier to contact during the trip for making changes (although I'm starting to doubt their customer service in light of our current problems booking tickets).
Anyway, I'm not sure this helps you at all, just another data point.
I expect the ticket will be cheaper if issued by LAN. AA only charges fuel surcharges on their on coded flights, but LAN doesn't charge any fuel surcharges at all (as far as I know).
AA will probably be easier to contact for changes, but for most changes you can just contact the operating airline anyway.
