In 2026, taking an intercity bus remains the most budget-friendly method for traveling between Boston and New York City. Operators such as FlixBus, Megabus, and Greyhound frequently offer one-way tickets starting as low as $10 to $20 when booked in advance, with most standard fares falling between $25 and $45. The journey typically takes about 4.5 to 5 hours, depending on traffic. For those who prefer the train, Amtrak's Northeast Regional can be affordable if booked early, with "Saver" fares sometimes starting at $31, though prices rise significantly closer to the travel date. While flying between Logan (BOS) and LaGuardia (LGA) is faster, the additional costs of airport transfers and baggage fees usually make it more expensive than ground options. For travelers focused strictly on the bottom line, the bus terminal at South Station offers the highest frequency of low-cost departures throughout the day and night.
