Are direct flights from Boston to San Jose always the best option?

Can flexible travel dates help on Boston to San Jose flights?

Yes, being flexible with your travel dates can significantly impact flight prices. Mid-week flights or those during off-peak seasons often have lower fares than weekend or holiday travel. Adjusting your departure or return by a day or two may result in considerable savings.

What extra costs should I check before booking Boston to San Jose flights?
