Also note that SYD-AKL J does not qualify for LAN's fast track to Emerald promotion (but AKL-SCL does, if you happen to fly that then it becomes much like the AA Plat challenge).
i didnot refer to the fast track. four roundtrips LHR-SYD will earn the required 150.000 kms. BUT in order to qualify you also need 4 segments on LAN metal. this is why i recommended the sidetrips SYD-AKL which are quite cheap to get (they may not be taken in J - cheapest economy also qualifies as LAN operated leg). another easy route is FRA-MAD where you can get the roundtrip for 81€ all in.
