✈️ Flight Guide: San Jose (SJC) → Boston (BOS)

January in Boston features museum exhibits, sports seasons and civic observances. Highlights include Martin Luther King Jr. Day programming and parades, winter exhibits at the Museum of Fine Arts and Isabella Stewart Gardner Museum, and professional sports (Boston Celtics and Boston Bruins home games) at TD Garden. Culinary events such as early-season Boston Restaurant Week (dates vary, often late January/early February) offer indoor dining experiences. Nearby Salem hosts year-round historic tours—expect slower crowds in January, making it a good time for off-season visits—while Cambridge’s university talks and galleries remain vibrant throughout winter.

Mid-to-late January is often the best time to fly from Norman Y. Mineta San Jose International Airport (SJC) to Logan International Airport (BOS) if you're seeking lower fares after the holiday spike. Book tickets around 3–6 weeks in advance and target midweek departures (Tuesday–Thursday) for cheaper options. Flying early morning reduces the chance of weather-related disruptions on the Boston side, while red-eye or overnight flights may occasionally be less expensive but can be more vulnerable to delays. If your trip is weather-sensitive, choose refundable fares or purchase travel insurance for January travel.

A nonstop flight (when available) from Norman Y. Mineta San Jose International Airport (SJC) to Logan International Airport (BOS) saves time and reduces the risk of missed connections, which is helpful in January when weather delays are possible. However, nonstop fares can be substantially higher or seasonal—so one-stop itineraries via SFO, LAX, DEN or ORD often provide more flexible schedules and lower prices. For business travelers valuing time, choose nonstop; for budget-conscious travelers, pick reliable connections with generous layovers and the same alliance partner to simplify rebooking in case of disruption.

Pack in layers: bring a warm coat, hat, gloves, water-resistant boots and thermal layers for Boston’s January weather. Keep an eye on weather forecasts from the National Weather Service and sign up for airline notifications to get timely information on delays or cancellations, particularly for connections in eastern hubs. Allow at least a 2–3 hour buffer for connections into Logan International Airport (BOS) during winter travel, and consider travel insurance for longer trips to cover weather-related rebooking and accommodations. Use credit card protections and airline apps for easy rebooking and to track gate changes, and always have chargers and portable batteries in carry-on bags during winter trips.

To secure cheap flights from Norman Y. Mineta San Jose International Airport (SJC) to Logan International Airport (BOS) in January, search 3–6 weeks before travel and compare multiple metasearch engines (Google Flights, Kayak, Skyscanner).
