Should have headed to Eastbay's cozy San Telmo apartment

Bad thing about LAN's Lounge, is that a lot of airlines are using it, and peak times are around 6-9. LAN, TAM, Iberia, AA.. they all use it.
Priority Pass gives you access to Star Alliance lounge. Platinum or Centurion cards, to the new Centurion Lounge. You could check those out if LAN's lounge is very crowded.
Safe flights
