Do airports themselves count as hidden cities when a bus trip is involved?
I fly mostly out of SFO but work down near SJC. Sometimes it's cheaper/more convenient to book a ticket out of SJC which involves a busride from SJC to the same flight that was more expensive directly out of SFO, although the reverse is a pain, so I'll ditch the bus on the way back.

Do the airlines consider the full route to be say BOS->SFO->Bus to SJC or just BOS->SFO?
