It was my understanding after years of fare-searching that US domestic fares are simply 2 one-way fare costs joined together. Is that no longer accurate (per above)? If yes I'll start changing my fare-search pattern to do roundtrip searches too.
Generally most domestic one-way fares are simply half of the roundtrip. In some rarer cases though, sale fares can require a roundtrip purchase to be valid. I would guess this falls into that group.
