UA has been flying this route regularly for awhile. It used to be a Shuttle route.
You are spot on with the prices. I can't book ex-SFO to SAN for less than $800 RT whenever I check. The best I've been able to do is when I either have a fixed departure or return is to book a cheap restricted OAK-LAX-SAN one way and WN fully refundable the other way (or vice versa). If the timing work out you can get on a mainline flight between OAK and LAX and go for the upgrade.
