Looking to spend several weeks in the south pacific later this year, hopefully getting to as many countries as possible. Plan for much of the trip is to base myself in Fiji, and make sidetrips from there. That said, many of the fares are outrageously expensive, $700-$1100 roundtrip. Looking to do Apia (APW), Funafuti (FUN), Honiara (HIR).

Are there any sorts of passes that might make this cheaper than buying three roundtrips? As it stands, the three roundtrips are looking at $2400+ booked that way
