I have been searching for a while and can't seem to get the details I am looking for. I am using some AA miles to book j seats to Buenos Aires from San Francisco over Thanksgiving and can either take the LAN Chile flight from LAX - Lima - Santiago - EZE or take LAN Peru from LAX - Lima - EZE. How is the inflight service, seat, entertainment on LAN Peru vs. LAN Chile/ Is there a difference? Worth an extra stop? I need the experts to help.....
