The best time to fly from San Diego International Airport (SAN) to find cheap economy fares is during shoulder seasons (September and early November) and midweek (Tuesdays/Wednesdays).

Use search filters for '1 stop' and 'connecting' and compare final prices including checked baggage and seat fees.
