Navigating Boston Logan International Airport (BOS) doesn't have to feel like a high-stakes puzzle. Located just three miles northeast of downtown Boston in East Boston, BOS handles tens of millions of passengers every year across four distinct terminals: A, B, C, and E. Whether you're catching a quick domestic hop or embarking on an international journey, knowing how the terminals connect, where to park, and how to beat security bottlenecks will save you time and stress.
Unlike sprawling mega-hubs out West, Logan is compact, which is both a blessing and a curse. Its tight footprint means shorter walks between gates in the same terminal, but transferring between certain terminals—especially international Terminal E and the others—can require navigating post-security gaps or hopping external shuttle buses. This guide breaks down terminal layouts, ground transportation choices, security hacks, and essential transit logistics so you can move through BOS like a local.
Understanding the Terminal Layout at BOS
Boston Logan features four operational terminals: Terminal A, Terminal B, Terminal C, and Terminal E. Each terminal serves specific airlines and offers its own mix of amenities, security checkpoints, and baggage claim areas.
- Terminal A: Primarily used by Delta Air Lines and WestJet. It features two separate satellite buildings connected by an underground moving-walkway tunnel equipped with art installations.
- Terminal B: Divided into upper and lower levels, Terminal B serves American Airlines, United Airlines, Air Canada, Alaska Airlines, and Spirit. It's split into two distinct structures (B-North and B-South) that aren't directly connected post-security, so check your boarding pass carefully before clearing checkpoint screening.
- Terminal C: Home to JetBlue, Aer Lingus, TAP Air Portugal, and Hawaiian Airlines. Terminal C connects post-security to Terminal E, making international transfers easier if you're flying partner airlines.
- Terminal E: The primary international gateway for BOS, serving carriers like British Airways, Lufthansa, Emirates, Air France, and Delta's international partners. Terminal E houses federal inspection services, customs, and global currency exchanges alongside duty-free shopping.
Ground Transportation and Getting to Downtown Boston
Leaving or arriving at Logan is heavily influenced by Boston's notorious traffic tunnels, specifically the Sumner and Callahan tunnels. Choosing the right transit method depends entirely on your destination and budget.
For budget-conscious travelers, public transit is the fastest option during rush hour. The Massachusetts Bay Transportation Authority (MBTA) operates the MBTA Blue Line subway from Airport Station, which connects directly to downtown in about ten minutes. Free shuttle buses (Massport Route 22, 33, and 55) run continuously between all airline terminals and the Airport Blue Line station.
Alternatively, the MBTA Silver Line (SL1) bus provides direct, free service from all terminal arrivals levels straight to South Station in the Financial District, where you can transfer to Amtrak or the Red Line.
If you prefer driving or ridesharing:
- Rideshare (Uber/Lyft): Pickup zones are centralized in designated areas, typically on the ground floor of the Central Parking garage. Follow signs for app-based rides from your terminal.
- Taxis: Readily available outside each terminal's baggage claim area on the ground level.
- Rental Cars: The Rental Car Center sits off-site and is accessible via dedicated blue and white Logan rental car shuttle buses operating 24/7 from every terminal.
Security Checkpoints and Expedited Screening
Security wait times at BOS fluctuate wildly depending on seasonal travel surges and morning banking banks for transatlantic flights. Knowing your checkpoint options helps minimize lines.
Every terminal has its own TSA screening checkpoints. If you have TSA PreCheck or CLEAR, look for dedicated lanes at Terminals A, B, C, and E. Terminal E features expanded biometric screening lanes that speed up international departures significantly. If you arrive early or encounter a massive line in your designated terminal, note that post-security airside walkways connect Terminals B, C, and E, though Terminal A remains completely isolated on the airside.
Amenities, Lounges, and Layover Survival
If you find yourself with hours to spare before boarding, Logan provides various dining and relaxation spots across its terminals.
- Dining: Skip generic fast food and seek out local flavors. Terminal A features local seafood favorites, while Terminal C boasts artisanal bakeries and local craft breweries pouring New England IPAs.
- Lounges: Premium travelers can access the Delta Sky Club in Terminal A, United Club and American Admirals Club in Terminal B, and various international alliance lounges in Terminal E, including the Air France/KLM Lounge and The Club BOS.
- Family and Accessibility: Nursing suites are available in every terminal, and pet relief areas are located both pre-security outside arrivals and post-security inside select terminals.
Frequently Asked Questions
Can I walk between all terminals at Boston Logan?
You can walk post-security between Terminals B, C, and E. However, Terminal A is entirely detached, and walking between terminals pre-security requires exiting the building and using the outdoor sidewalks or free terminal shuttle buses.
How early should I arrive for my flight at BOS?
Massport recommends arriving at least 2 hours before domestic flights and 3 hours before international flights. If you are traveling during peak morning rush hours (6:00 AM to 9:00 AM) or holiday weekends, add an extra 30 minutes to account for parking shuttles and security queues.
Is there luggage storage inside Boston Logan Airport?
Due to federal security regulations, there are no public lockers or luggage storage facilities available inside the terminals at BOS. Plan your baggage logistics accordingly if you have a long daytime layover and want to explore the city.
What is the best way to park long-term at the airport?
Logan offers Central Parking and Economy Parking options. Central Parking sits within walking distance of Terminals A, B, and C, while the Economy Parking garage requires a short, free shuttle ride to the terminals. Reserving parking online ahead of time through the official airport portal often guarantees lower daily rates and a guaranteed space.
