Best Time to Book

Book your Seattle to San Diego flight 38 to 50 days before departure for the best prices.

If you're planning to fly from Seattle to San Diego, the best strategy is to book your flight between 38 to 50 days before departure, as prices remain low during this window, especially around 47 days out. Booking any earlier may lead to higher costs, around $319. Waiting until closer to departure increases the price risk significantly, peaking at around $344, while only the 28-day mark offers slight price dips. Therefore, to avoid high prices, aim to book early within this optimal window.
