I'll +1 that sentiment, but they be the OneWorld carrier in South America. A third-world airline in many ways. And the OneWorld "Visit..." fares are a bargain.

On one of those, we missed a connection at SCL and were accommodated on the next flight to BA. End of story. Next flight was AEP-USH, no problem. Excitement came some time later when attempting to check in for USH-AEP; the missed connection had cancelled the rest of our reservations. In the Christmas-New Year's period.

LAN res was unsympathetic to the point where I'm sure I heard "F... you" subvocalized. Go talk to AA. (the RTW desk handled/handles these fares). I could have called back hoping for a friendlier agent, but since the desk was open and was staffed with known-helpful people I called them. "Shouldn't be our problem, but we'll take care of it and get right back to you." And so they did, grabbing available space as required, above the booking class.
