3. Leverage Airline Loyalty Programs
Both Southwest and American Airlines offer rewards points that can significantly reduce or even waive flight costs. Membership in these frequent flyer programs often doubles the value of a low-fare ticket.

4. Consider Primary vs. Hub Airports
While some flights depart from San Diego International Airport (writing San Diego SD) or Phoenix Sky Harbor (PHX), hub transfers may add minor convenience costs. Mainline flights between SD and PHX stay consistently affordable and simplify booking.
