Not that anyone flying out of Santiago in the near future will read this thread, but….We were on an AA flight that left at midnight. Got to the airport at 7 and were able to check in right away, including bag drop. We sailed through security and didn’t have to remove anything from our carry ons, including liquids. I thought suh-weeet! Great news so far. The AA website for lounge access said One World Sapphire and Emerald could use either of two Latam lounges, even though I questioned that twice directly with AA because the wording was confusing and as recently as the day before we flew. AA contact assured me we did have access. Strutted right up to the counter with another couple that we were pretty sure we could include as guests. Welp, AA hasn’t had lounge access with Latam for THREE years. Slightly embarrassing. Very nice Latam guy pointed us to the Pacific Princess lounge that does admit AA. Off we trotted (it’s a big airport). We were able to enter that lounge. To say it was minimalist is being generous. It was also full to the gills, literally no place to sit, and worst of all, no alcohol since they hadn’t gotten their license. And it had tons of families with young children. We left. Fortunately, as we were waiting for the elevator, we noticed the lounge next door took Priority Pass, and the couple with us were members. It was much nicer and not crowded while we were there. When it was time to board, I stopped and bought a bottle of water. When boarding was called, I noticed about a dozen terminal employees were lined up with tables in the jet bridge where they searched carryons and promptly confiscated my unopened water bottle because “the U.S. doesn’t allow liquids over 3 ounces.” *****?? I asked why do they even sell water after security then?? But, I rant. Sorry. The only other semi-interesting thing was all electronics had to be completely powered down for taxi and takeoff. That was a first for us.
