Courtesy of the other board. You get booked into domestic first on AA and Business class for long haul on 4M LAN Argentina. They have a lie flat bed in biz and from what I have read around the forumsphere good service all around. Elite Status bonus is viable on 4M portion of flights. It is bookable on aa.com but because the 4M flights don't have AA flight numbers you CAN'T put a free 24hr hold on these bad boys.
