Are Boston Airport Terminals Connected? | Navigating Logan

Boston Logan International Airport (BOS) terminals are not physically connected airside, requiring passengers to exit security for transfers between most terminals.

Navigating an airport often presents unique challenges, especially when connecting flights or switching airlines. Boston Logan International Airport, a key gateway to New England, has a distinct layout that travelers need to understand for smooth transitions. Knowing how its terminals are arranged can save significant time and stress.

Understanding Boston Logan’s Layout

Boston Logan International Airport operates with four distinct terminals: A, B, C, and E. These terminals are largely independent structures, a crucial detail for anyone planning a transfer. The primary distinction for travelers is between “airside” and “landside.” Airside refers to the areas past security checkpoints, while landside encompasses everything before security, including check-in counters, baggage claim, and ground transportation.

Each terminal at BOS primarily serves specific airlines, which helps in initial orientation. Terminal A is home to Delta Air Lines, Terminal B hosts American Airlines, Southwest Airlines, and United Airlines. JetBlue Airways and Aer Lingus operate from Terminal C, and Terminal E is the primary hub for most international carriers, alongside Spirit Airlines.

The physical separation of these terminals means that, for most connections, you will need to exit the secure airside area of your arriving terminal, travel landside to your departure terminal, and then re-enter security. This process is standard for airports with disconnected terminal structures.

The Four Terminals: A, B, C, E

• Terminal A: Modern and spacious, Terminal A primarily serves Delta Air Lines and WestJet. It features two concourses connected by an underground walkway.
• Terminal B: This terminal is divided into North and South sections. American Airlines, Southwest Airlines, and United Airlines operate from Terminal B. A post-security walkway connects some gates within Terminal B, but not to other terminals.
• Terminal C: JetBlue Airways and Aer Lingus are the main occupants of Terminal C. It’s centrally located and has undergone significant renovations.
• Terminal E: Designated as the International Terminal, Terminal E handles the majority of international arrivals and departures, along with Spirit Airlines. All international arrivals must clear customs and immigration here.

Airside vs. Landside Connections

The concept of airside versus landside is central to understanding transfers at Logan. An airside connection allows you to move between gates or concourses without re-entering security. At BOS, true airside connections between different terminals are generally not possible.

Landside connections involve exiting the secure area, navigating the airport’s public spaces, and then re-entering security at your next terminal. This is the predominant method for inter-terminal transfers at Logan. Be prepared for security re-screening, which is a standard procedure when moving between separate terminal buildings.

Navigating Between Terminals: Your Options

Since most Logan terminals are not connected airside, efficient landside transportation is essential. Fortunately, Boston Logan provides several well-organized options to move passengers between terminals, the MBTA Blue Line station, and the Rental Car Center.

The Massport Shuttle Bus system is the backbone of inter-terminal transportation. These buses are free, run frequently, and operate 24 hours a day, seven days a week. They are designed to simplify the transfer process for all travelers, including those with luggage or mobility needs.

The Massport Shuttle Bus System

The Massport Shuttle Buses offer reliable service on multiple routes, ensuring comprehensive coverage of the airport. These buses are clearly marked and stop at designated areas outside each terminal’s baggage claim level. They provide direct connections to all terminals, the MBTA Blue Line Airport station, and the Rental Car Center.

Routes are designed to minimize travel time, though specific routes and frequencies can vary slightly based on demand and time of day. It is always wise to check the Massport website for real-time shuttle tracking and the most current schedule information.

Walking Paths and Moving Walkways

While the shuttle is the primary method, some limited walking options exist. Within Terminal B, moving walkways connect the two concourses post-security. Between Terminal B and Terminal C, a landside walking path is available, but it requires exiting security and navigating outdoor areas, which can be challenging with luggage or during inclement weather.

Walking between Terminal C and Terminal E is also possible landside, being the closest terminals. However, for any significant distance or with time constraints, the Massport Shuttle remains the recommended choice for comfort and efficiency. Always factor in weather conditions if considering walking between terminals.

Security and Re-screening Considerations

The necessity of re-clearing security is a critical aspect of most terminal transfers at Boston Logan. Understanding this requirement and planning for it can greatly reduce stress and potential delays during your connection.

Each terminal at BOS has its own security checkpoints. When you move from one terminal to another, even if it’s a short distance landside, you will need to go through a new security screening process. This applies to all passengers, including those with connecting flights.

TSA PreCheck and CLEAR at BOS

Programs like TSA PreCheck and CLEAR can significantly expedite the security re-screening process. If you are enrolled in TSA PreCheck, you can use dedicated lanes that often have shorter lines and less intrusive screening procedures. CLEAR offers an even faster path through security by verifying your identity using biometrics, allowing you to bypass the initial ID check line.

Both programs are available at Boston Logan’s security checkpoints in all terminals. Utilizing these services can save valuable time during a terminal transfer, helping you make your connecting flight with greater ease. According to the TSA, enrollment in these trusted traveler programs allows for a more streamlined experience at airport security checkpoints.

International Arrivals and Customs

For international arrivals at Terminal E, the process involves additional steps beyond standard security. Upon landing, all passengers must proceed through U.S. Customs and Border Protection (CBP) for immigration and customs clearance. After clearing CBP, you will collect any checked luggage, even if it was tagged for a final destination.

Following baggage retrieval, you must re-check your bags at a designated re-check counter for your connecting flight. Only after completing this process can you proceed landside to your next terminal and re-enter security for your domestic departure. This multi-step process requires ample time, making generous connection windows essential for international transfers.

Time Management for Terminal Transfers

Effective time management is paramount when planning a transfer at Boston Logan. The disconnected nature of the terminals, coupled with security re-screening, means that you cannot assume a quick dash between gates will suffice. Proper planning ensures a relaxed and successful connection.

Several factors influence the time required for a smooth terminal transfer, including the specific terminals involved, the time of day, and any potential delays. Always build in a buffer beyond the airline’s minimum connection time, especially if you are unfamiliar with the airport or have mobility considerations.

Recommended Connection Times

1. Domestic to Domestic (different terminals): A minimum of 2.5 to 3 hours is advisable. This allows for deplaning, shuttle travel, and re-clearing security at the new terminal.
2. International to Domestic: Plan for at least 3 to 4 hours. This accounts for immigration, customs, baggage re-check, shuttle transfer, and security re-screening.
3. Domestic to International: A 3-hour window is generally recommended. While you won’t clear U.S. customs on departure, you still need to transfer terminals and re-clear security, then check in for your international flight, which often has earlier cut-off times.

Factors Affecting Transfer Speed

Several elements can impact how quickly you can navigate a terminal transfer. Peak travel times, such as early mornings, late afternoons, and holidays, typically mean longer lines at security and busier shuttle buses. Inclement weather, common in Boston, can cause flight delays and affect ground transportation, adding unforeseen complications.

Your personal mobility, the amount of luggage you are carrying, and whether you are traveling with children or individuals needing special assistance will also influence your transfer speed. Factor in extra time if any of these apply to your situation. Having mobile boarding passes ready and knowing your next gate before you land can also shave off precious minutes.

Specific Terminal Connection Scenarios

Understanding the most common terminal transfer routes at Logan can help you visualize your journey. While the Massport Shuttle is the consistent solution, knowing the proximity and specific challenges of certain pairings helps in preparation.

The layout of Logan means some transfers are relatively straightforward via shuttle, while others involve longer distances. Always confirm your arrival and departure terminals and plan your route accordingly. A quick check of the airport map before your trip can be highly beneficial.

Terminal B to Terminal C

Terminals B and C are adjacent to each other, making them appear close on a map. However, they are not connected airside. To transfer between them, you must exit security from your arriving terminal, then either walk landside or take a Massport Shuttle bus. The shuttle is often the more convenient option, especially with luggage.

Once you arrive at your connecting terminal, you will proceed to the security checkpoint for re-screening. This transfer is one of the more frequent at Logan, given the airlines operating from these terminals, so the shuttle service is typically efficient on this route.

Terminal A to Terminal E

Transferring between Terminal A (Delta) and Terminal E (International) represents one of the longer inter-terminal journeys at Logan. These terminals are located on opposite sides of the airport’s central area. The Massport Shuttle bus is the only practical and recommended method for this transfer.

Allow ample time for the shuttle ride, which can take 10-15 minutes depending on traffic and stops, in addition to the time needed for security re-screening. This route is common for travelers connecting from a domestic Delta flight to an international departure, or vice versa.

Amenities and Services During Transfers

Even during a transfer, you might find yourself with some time to spare landside. Boston Logan offers a range of amenities and services in its public areas that can make your wait more comfortable or productive.

From diverse dining options to retail stores, there are opportunities to grab a meal, pick up forgotten items, or simply relax. Knowing what’s available can enhance your transfer experience, especially during longer layovers.

Dining and Retail Options

Each terminal at Logan provides a selection of dining establishments, from quick-service eateries to sit-down restaurants, both airside and landside. During a landside transfer, you have access to the pre-security food courts and shops in each terminal. This provides flexibility for meals or last-minute purchases.

Retail stores offer everything from travel essentials and souvenirs to fashion and electronics. Exploring these options can be a good way to pass the time if you have an extended layover between flights.

Rest Areas and Lounges

While dedicated rest areas are limited, many terminals offer comfortable seating in public areas. If you have access to an airline lounge (e.g., through a premium ticket, elite status, or a credit card), remember that these are typically located airside within specific terminals.

If your transfer requires exiting security, you will lose access to the lounge in your arriving terminal and will only be able to access a lounge in your departure terminal after re-clearing security there. Plan accordingly if lounge access is a priority for your comfort during a layover.

Accessibility and Special Assistance

Boston Logan is committed to providing an accessible environment for all travelers. Services and facilities are in place to assist passengers with disabilities or those requiring special assistance during their journey and transfers.

It is always recommended to arrange any specific assistance, such as wheelchair services, directly with your airline in advance of your travel date. This ensures that help is ready and waiting upon your arrival and departure.

ADA Compliance and Services

Logan Airport adheres to Americans with Disabilities Act (ADA) guidelines, offering accessible restrooms, elevators, and ramps throughout its terminals. The Massport Shuttle buses are wheelchair-accessible, ensuring that all passengers can utilize this crucial inter-terminal transportation method.

For passengers with hearing impairments, TTY phones are available in all terminals. Information desks are staffed by personnel who can provide assistance and guidance for travelers with diverse needs, offering real-time help with airport navigation and services.

Family and Pet Relief Areas

Traveling with family often means needing specific amenities. Family restrooms are available in all terminals, providing private and spacious facilities for parents with young children. These are typically equipped with changing tables and offer a more comfortable space.

For those traveling with service animals or pets, Boston Logan provides designated pet relief areas. These are located both airside and landside in all terminals, offering convenient and clean spaces for animals to relieve themselves. Look for clear signage directing you to these facilities.
