Tips for cheap San Francisco to San Diego flights

Large conventions downtown can push up both airfare and hotel prices; check event dates before you lock in travel.
Flexible by a day or two? Compare the fare calendar - moving your trip slightly can save a lot.
Compare one-way fares on different airlines for each direction; it is sometimes cheaper than a round trip on one airline.

Tips for a smooth trip

San Diego International Airport has two terminals. Check which one your airline uses, as it makes pick-ups and rental car returns easier.
