played around for a while, this can be a great trip to take given the stamina and time, and base on my limited knowledge about AS, it can earn a lot of miles.(book into V,S,N on LA stock so that is 100% on AS I assume?) ICN-MAD-SCL-MAD-FRA-HND earns almost 50k for MVP75K if my calc are correct.
if depart from ICN it is apparently difficult to build a stopover on the outbound no matter where, and if you want to visit IPC/PPT you have to leave from c6. you can return to KIX, OKA etc for a bit more. inbound can have multiple stopovers in c4,c2,c3,but anything complicated chokes google to produce a link to priceline, such as mixing in carriers like JL and sometimes EK. (the stopovers give FTers based in c2 a good chance to break up the legs, or just hop off at any gateway in c3 like PEK,ICN,TPE,HKG,SHA,BKK. fyi, PPT-IPC only runs on tuesdays)
wonder also why only ICN works for c3 (LA should publish fares to China and others right?), and c1/c2 seems impossible as an origin.
