Cons: On both legs from my trip to and from Rio Gallegos, I briefly asked staff members at the departure gate counter to confirm the gate number for my flight as the gate screens didn't yet have the destination and flight # shown. Both staff members were rude, displaying a sort of "annoyed-ness" for being asked questions.
The planes are ok, no entretainement and the snacks were industrialized cookies. I guess that is ok given that either flight was 3 hrs only, but considering that I paid US$800 for this trip, I'd expect better quality. So, honestly, I'll avoid AA if I have any other competitive alternative.
