So the wiki post above says LA will not check through separate PNRs (own or partner).
Does anyone know whether that's an official LA position? The reason is because about three weeks ago LA did check our luggage through (LA to LA). We were flying on two separate PNRs - LA800 SYD to SCL (award) and LA640 SCL to LIM (revenue). At check-in I asked if she could check through our luggage and she just said yes.
