Replying to myself since I can't edit: I see two replies suggesting that what I want is a multi-city trip, but that's not the same thing. Flights will happily let me do the same search I can do on Orbitz, with my start/end city being "SF metro area, any airport". But unlike Orbitz, when I use that I can't book an itinerary that goes SFO-BOS-SJC, for example. (I don't want to search it as multi-city, because then I have to _manually_ try every combination of SFO/SJC/OAK until I find what's cheapest.)
