When is the cheapest time to fly San Juan to San Francisco?
Fares on the San Juan–San Francisco route are usually lowest when you book 3 to 10 weeks ahead and fly mid-week (Tuesday or Wednesday). Prices climb sharply in the final two weeks and around holidays and peak summer travel. Because airlines release a small number of discounted seats on each flight, the best fare can disappear within hours — that's why a quick call often beats refreshing booking sites for days.
