Travel Tips
For a seamless journey from Baltimore to Boston, consider booking your flight at least three weeks in advance to secure the lowest fares, as this business-heavy route can see significant price spikes closer to the departure date. If you have flexibility, flying on a Tuesday or Wednesday often yields the best value and results in fewer crowds at the security checkpoints. For those traveling light, taking the MARC or Amtrak train to the BWI Rail Station is a cost-effective way to reach the airport, while in Boston, the Silver Line T provides a free and convenient connection from the terminals directly into the city's South Station. Always check the weather forecast for both cities during winter months, as Nor'easters can cause unexpected delays or cancellations across the regional airspace.
