I get to the airport and try to check in at the international terminal.  Ooops,  since I am first going to LA,  I need to check in at the domestic side at American Airlines.  I get there and try to check-in at the kiosk but my flight info could not be found.  I go to the counter and they can't find it either.  They call LAN airlines and the only thing that they can tell me is that the flight got canceled - they didn't say why or when.  Then they tried to reroute me, but all flights to LAX are booked for today. I am now getting another flight leaving SFO on Sunday evening and arriving into Peru a day later, too.
