Hi-

I will soon be starting to shop for a SFO-EZE and then SCL-SFO trip for a South American Cruise next year. The 3 products offered by the US legacy carriers all look and are priced similarly. I was wondering if anyone has an opinion as to why one might have the edge over the other like, seat comfort, food ...ect. There's a small chance I might be on a LATAM leg coming back from SCL an even smaller chance I might be on AC going to Argentina. I not a slave to miles or points, I currently accounts but do not have status on UA, DL, AA, AS, SWA and Hawaiian!

Thanks,

Paul
