✈️ Flight Guide: Boston (BOS) → San Diego (SAN)

December in San Diego offers festive experiences perfect for travelers arriving from Boston Logan International Airport (BOS). Key highlights include Balboa Park holiday lights and museum nights, SeaWorld’s Christmas Celebration, and seasonal markets in the Gaslamp Quarter. Many attractions offer special hours and ticketed events, so reserve in advance during the holiday period. Use public transit or pre-booked shuttles from San Diego International Airport (SAN) to reach venues quickly and make the most of short December daylight hours.

The best time to fly from Boston Logan International Airport (BOS) to San Diego International Airport (SAN) in December is midweek and early morning to avoid holiday peak crowds and reduce weather-related delays. Avoid peak holiday departure days immediately before major holidays (e.g., Christmas week) when fares and demand spike. If flexibility is available, departing on Tuesdays or Wednesdays and returning midweek typically yields lower prices and fewer airport crowds. Book early and set fare alerts to secure the best December rate.

Direct (nonstop) flights from Boston Logan International Airport (BOS) to San Diego International Airport (SAN) save time and reduce the risk of missed connections, especially important in December when winter weather can disrupt schedules. However, connecting flights are often cheaper and more flexible with more daily options; if you prioritize cost over time, a one-stop itinerary through a major hub may be best. For holiday travel, consider the trade-off: pay a premium for nonstop reliability or save money with connections while building in longer layovers to mitigate delay risk. Compare both options and book the one that matches your priorities and budget.
