American Airlines has a low fare today for San Francisco to Sao Paulo at $665 or Rio De Janeiro $685. This is the lowest fare I’ve seen in six weeks and beats $703 LAX fares from March 22 with United and Delta.
Sao Paulo has more overall availability. Rio has at least a few dates in each month at low fare, but first half of October has most availability.
Los Angeles is in $700s. Seattle in $800s when these fares were found from San Francisco.
