Flying San Diego-San Francisco

One option for driving the Pacific Coast Highway is to fly in to San Diego or San Francisco, book a one-way car rental airport to airport, and fly back from the other end. However, one-way car rentals are usually more expensive, incurring a drop fee, and it may be cheaper to drive back on the faster Interstate. As well as Southwest Airlines, Virgin America and United also fly between San Diego and San Francisco.
