Cheap flights from New York to San Jose (JFK to SJC) from $254

Book at the right time: For domestic routes like New York to San Jose, the sweet spot is 3–5 weeks before departure. Booking too early can mean missing seat sales; too late means paying peak prices.

Shift your dates by a day or two: Mid-week departures (Tuesday–Wednesday) are almost always cheaper than weekend flights. Even shifting by one day can make a meaningful difference.

Direct flights are available: Direct flights take around 11h 23m and are worth it for convenience — but check if a one-stop flight is significantly cheaper before ruling it out.

Factor in baggage fees: Low-cost carriers on this route often advertise attractive base fares but charge separately for checked luggage. Always compare the all-in price — a $20 cheaper fare plus $50 baggage fee is no saving. Alaska Airlines and American Airlines may have different inclusions, so check each airline's fare conditions.
