I am considering flying LAX/DUB/LIM/LAX in J

Is this a One World explorer( 3 continents) tix that I need?

How is this priced? Continents visited or miles travelled?

Seems like this requires a 10 day stay- what are my options on lesser time? I really don't want to be away that long

Am considering LAX /DUB ( either AA via ORD or LHR or maybe AA to vancouver and then BA ex vancouver for the seats)
then IB DUB/MAD/EZE
Then LP eze/lim
then LAN LIM/LAX

Thank you.

I do a few Circle pacific fares, but have never done this type
