Techie booking question for people far more learned than I.

I see this (rather good) rate for a last minute trip to SFO next week. I can't get it to price anywhere (BA, Kayak, Expedia). Am I missing something or is a phantom fare which isn't actually bookable somehow? I have emailed my travel agent but thought I'd also seek advice from the FT crowd

Any help much appreciated.
