Public Transit Options: MBTA Red Line to South Station, then Silver Line to airport
One of the most efficient and cost-effective ways to travel from Porter Square to Boston Logan International Airport is by utilizing the MBTA’s public transit system. This route combines the reliability of the Red Line subway with the convenience of the Silver Line bus rapid transit, ensuring a seamless journey to the airport. Here’s how to navigate this option step by step.
Step 1: Begin at Porter Square Station
From Porter Square, head to the MBTA Red Line station, located directly beneath the Porter Square Shopping Center. The Red Line is one of Boston’s busiest subway routes, running from Alewife to Ashmont/Braintree. Board an inbound train heading toward Ashmont or Braintree—either will take you to South Station, your next transfer point. The ride from Porter Square to South Station takes approximately 15 minutes, depending on time of day and train frequency.
Step 2: Transfer to the Silver Line at South Station
Upon arriving at South Station, follow signs to the Silver Line bus terminal. The Silver Line operates as a surface-level rapid transit service, with routes SL1 and SL3 providing direct access to Logan Airport. The SL1 is the most direct option, stopping at all airport terminals. The transfer from the Red Line platform to the Silver Line terminal is straightforward, with clear signage guiding passengers. The Silver Line departs frequently, with wait times typically under 10 minutes during peak hours.
Cautions and Practical Tips
While this route is generally reliable, it’s important to plan for potential delays, especially during rush hour or inclement weather. The Silver Line shares road space with other vehicles, making it susceptible to traffic congestion. To mitigate this, allow at least 90 minutes for the entire journey, including transfer time. Additionally, consider traveling outside of peak hours (before 7 a.m. or after 9 a.m.) for a smoother experience. For real-time updates, use the MBTA’s mobile app or check service alerts online.
Cost and Accessibility
This transit option is budget-friendly, with a standard one-way fare of $2.40 for the subway and $2.40 for the Silver Line, totaling $4.80. Passengers using a CharlieCard can benefit from a discounted fare of $2.25 per leg. The entire route is accessible for individuals with disabilities, with elevators and ramps available at both Porter Square and South Station. However, it’s advisable to verify Silver Line accessibility in advance, as not all buses may be equipped with functioning lifts.
Combining the MBTA Red Line and Silver Line offers a practical and affordable solution for traveling from Porter Square to Logan Airport. With careful planning and awareness of potential delays, this route ensures a stress-free journey. Whether you’re a commuter or a visitor, this transit option exemplifies Boston’s interconnected public transportation network, making airport access both convenient and economical.

Rideshare Services: Use Uber or Lyft for direct, convenient, and quick airport transportation
Need a hassle-free way to get to the airport from Porter Square? Consider using rideshare services like Uber or Lyft. These platforms offer a direct and convenient solution, eliminating the need to navigate public transit schedules or hail a cab. With just a few taps on your smartphone, you can request a ride, track its arrival in real time, and enjoy a comfortable journey to the airport.
Here’s how it works: open the Uber or Lyft app, enter your destination (e.g., Logan International Airport), and select the type of ride that suits your needs—whether it’s a budget-friendly option or a more spacious vehicle for extra luggage. The app will provide an estimated fare and arrival time, so you can plan accordingly. Pro tip: schedule your ride in advance if you’re traveling during peak hours or have a tight flight schedule. This ensures a driver is ready when you are, reducing stress and last-minute delays.
One of the standout advantages of rideshare services is their flexibility. Unlike public transportation, which operates on fixed routes and schedules, Uber and Lyft adapt to your timeline. Need to leave at 4 a.m.? No problem. Have multiple bags or traveling with a group? Choose a larger vehicle option. Plus, rideshare drivers are often familiar with the quickest routes, helping you avoid traffic and arrive at the airport promptly.
Cost-wise, ridesharing can be competitive, especially when compared to parking fees or the unpredictability of taxi fares. While prices may surge during high-demand times, the transparency of upfront pricing allows you to make an informed decision. For added savings, consider pooling your ride with others heading in the same direction, though this may add a few minutes to your trip.
In conclusion, Uber and Lyft provide a reliable, user-friendly, and efficient way to travel from Porter Square to the airport. By combining convenience, flexibility, and affordability, these rideshare services stand out as a top choice for travelers seeking a stress-free start to their journey. Just remember to factor in extra time for potential traffic and airport security, and you’ll be ready to take off with ease.

Taxi Services: Hail a cab from Porter Square for a straightforward, no-wait airport trip
Hailing a cab from Porter Square offers a direct, stress-free solution for reaching the airport without the guesswork of public transit or the unpredictability of rideshares. Unlike apps that require advance booking and may surge in price during peak hours, taxis are readily available at designated stands or via a quick phone call to local companies like Metro Cab or Independent Taxi. This immediacy makes them ideal for last-minute travelers or those with tight schedules, ensuring you’re on the move within minutes of stepping outside.
The simplicity of this method lies in its transparency. Unlike rideshares, where drivers may cancel or struggle to locate you, taxis operate on a straightforward model: flag one down, state your destination, and pay upon arrival. Most drivers are familiar with the quickest routes to Logan Airport, factoring in real-time traffic to minimize delays. For added peace of mind, ask for an estimated fare upfront—while not legally required in Massachusetts, many drivers will provide one, helping you budget accordingly.
While taxis may cost more than public transit, their convenience is unparalleled, especially for early morning or late-night flights. A typical trip from Porter Square to Logan takes 20–30 minutes, depending on traffic, and costs around $40–$50, including tolls. To streamline the process further, have cash or a credit card ready, as most cabs accept both. If traveling with bulky luggage, confirm the vehicle can accommodate your bags—most standard taxis can handle 2–3 suitcases without issue.
For those prioritizing reliability, consider pre-arranging a taxi pickup through a local company. This ensures a cab will be waiting at your doorstep, eliminating even the minimal wait time at a stand. Alternatively, if you prefer spontaneity, Porter Square’s high foot traffic means taxis frequently pass through, particularly near the MBTA station. Whichever approach you choose, this method delivers on its promise: a straightforward, no-wait journey to the airport, leaving you free to focus on your travels ahead.

Driving Directions: Take I-93 South to airport exit, follow signs to terminals
Navigating from Porter Square to the airport via I-93 South is a straightforward route, ideal for those who prefer driving. Begin by heading southwest on Massachusetts Avenue toward Porter Square, then merge onto I-93 South via Exit 26B. This highway is your direct line to the airport, typically a 20- to 30-minute drive depending on traffic. Keep an eye on the signs as you approach the airport exit, as they will guide you seamlessly to the terminals. This route is particularly efficient during off-peak hours, making it a reliable choice for time-sensitive travelers.
While the directions seem simple, there are a few nuances to consider. After taking the airport exit, you’ll encounter a series of signs directing you to specific terminals. Pay close attention to these, as missing a sign could lead to unnecessary detours. For instance, Terminal A and B are typically accessed via the left lanes, while Terminals C and E are on the right. If you’re dropping off passengers, follow the "Departures" signs; for pickups, look for "Arrivals." Familiarizing yourself with these details beforehand can save valuable minutes.
One practical tip for drivers is to check real-time traffic updates before departing. Apps like Google Maps or Waze can alert you to accidents, construction, or heavy congestion on I-93 South. If delays are significant, consider taking an alternate route, such as Route 28 South, though this may add time to your journey. Additionally, ensure your vehicle has sufficient fuel, as there are limited gas stations along the direct I-93 route. Planning ahead minimizes stress and ensures a smooth arrival.
For those traveling during peak hours, such as early mornings or late afternoons, allow extra time to account for slower traffic. I-93 South is a major artery for commuters, and bottlenecks are common near the airport exit. If you’re driving a rental car, double-check the return location, as some rental agencies are off-site and require a shuttle. Finally, keep your parking plans in mind—whether you’re using airport parking or a private lot—and factor in the time needed to reach your terminal from there. With these considerations, the I-93 South route becomes not just a set of directions, but a strategic plan for a hassle-free airport arrival.

Biking Route: Ride along Mass Ave to Cambridge Street, then follow airport bike paths
Navigating from Porter Square to Logan Airport by bike is a feasible and scenic option for those who prefer an active commute. The route begins by heading southeast on Massachusetts Avenue, a well-traveled artery that connects Cambridge to Boston. This initial stretch is straightforward, with dedicated bike lanes in most sections, ensuring a safer ride through urban traffic. As you approach Central Square, the bustling atmosphere provides a lively backdrop, but stay alert—this area can be congested, especially during peak hours.
From Central Square, continue on Mass Ave until you reach the intersection with Cambridge Street. Here, turn right onto Cambridge Street, which marks the transition from the city’s core to a more industrial landscape. This segment is less crowded, allowing for a smoother ride as you approach the Charles River. The river serves as a natural boundary, signaling that you’re nearing the airport’s vicinity. Look for signage directing you to the airport bike paths, which are well-marked and designed to guide cyclists through the final leg of the journey.
The airport bike paths are a cyclist’s ally, offering a direct and protected route to Logan Airport. These paths are separated from vehicular traffic, reducing stress and increasing safety. Follow the signs for your specific terminal, as the airport’s layout is bike-friendly, with designated lanes and ample bike racks near each terminal. Be mindful of pedestrians and shuttle buses in the airport area, as these paths can be busy, especially during peak travel times.
For practical tips, ensure your bike is equipped with lights and reflective gear, as portions of the route may be dimly lit, particularly in the early morning or evening. Carry a water bottle and a basic repair kit, as the 6-mile journey can be physically demanding. Check weather conditions beforehand, as strong winds or rain can make the ride more challenging. Finally, allow at least 45 minutes to an hour for the trip, factoring in potential delays due to traffic or navigation. This biking route not only offers a cost-effective and eco-friendly option but also a unique way to experience the transition from Cambridge’s charm to Boston’s bustling airport hub.
