Sad to see LA go from OW, used them quite a bit when I lived in SCL. I used to do SCL-JFK sometimes via LIM with a 2-3 day stopover in NYC and then take AY 006. Did the same on the return with one night somewhere in Jamaica (Queens). Also took the MAD-FRA once.
I will certainly not miss the LATAM crowd in the JFK Flagship Lounge. They can go disturb the peace in the T4 Delta SkyClub instead.
