The sample routings show using AA flights on the fare (possibly QF codeshares as there are many, but LGA-YUL-ORD-HNL is a fairly unlikely QF codeshare route). Either this is a mistake, or it is really a BA/QF/AA RTW, which might make it considerably more attractive. Even if it is restricted to QF codeshares on AA, it would allow routings like LHR-MIA-LAX. It must also include QF codeshares on LAN if they really allow travel via South America (SYD-AKL-SCL is the only way without going through North America again, though maybe they allow LHR-EZE-LAX-SYD). Finally the booking code for the BA WT+ portions is likely to be W so earning full economy SC and 110% miles; and probably better availability esp if you are willing to downgrade. If the rules are really as described, this is quite a bit better than the LONE4.
