For August travel, the best time to fly from Logan International Airport (BOS) to San Diego International Airport (SAN) is midweek (Tuesday–Thursday) and in early morning departures to avoid airport crowds and minimize delay risk.

Nonstop flights from Logan International Airport (BOS) to San Diego International Airport (SAN) save time and reduce connection risk—especially valuable in August when travelers want to maximize beach and event time.
