Update: The current AA lounge is a pretty new and sizeable Primeclass Pacifico lounge (bigger than the Skyteam lounge) located at the very end of the C pier, one level down (seems to be the norm at SCL). Lots of different seating options including chaises in semi-private cubes, a 1-person meeting room and a 6-person conference room which was occupied by the entourage of LatAm celebrity singer. WC and showers available inside. There were decent but not amazing food options including 3 hot dishes, a few cold dishes, and desserts. The bartender was happy to make any cocktail you chose, wine was meh. All in all happy to spend a couple hours there.
