Navigating Boston Logan International Airport Terminal B can feel like threading a maze if you don't know its layout ahead of time. Split into two distinct sections—Pier B (north) and Pier C (south)—the terminal handles massive volumes of domestic and regional traffic for major carriers like American Airlines, United, and Southwest. Because the two sides were historically separate buildings, walking into the wrong entrance or picking the incorrect security checkpoint can force a lengthy backtrack or require you to exit and re-clear security.
This guide breaks down the terminal's architecture, airline assignments, parking strategies, and transit options so you can move through the hub like a seasoned traveler.
Terminal B Layout and Security Checkpoints
Terminal B wraps around its own dedicated parking garage in a wide U-shape. The structure is divided into two primary passenger concourses: the B-North pier and the B-South pier.
- The Airside Connection: A post-security walkway links the northern and southern halves of Terminal B. However, entering through the wrong side forces an unnecessary walk before you clear TSA.
- Checkpoints: Each pier has its own security checkpoint. Check your boarding pass for your gate number before entering the terminal building to pick the closest line and avoid extra steps.
- Level Configuration: Level 1 houses baggage claim, Level 2 handles check-in and ticketing, and pedestrian bridges connect directly to the Terminal B parking garage from the upper levels.

Airlines Operating in Terminal B
Knowing your airline determines which curb to target for drop-off and which security line to join. Terminal B serves several major carriers:
- American Airlines: Operates out of the B-South pier, handling both heavy domestic schedules and select international departures.
- United Airlines: Primarily occupies the B-North pier with robust mainline and regional connections.
- Southwest Airlines: Operates out of Terminal B, utilizing dedicated check-in counters on the departures level.
- Air Canada: Handles both domestic and international departures and arrivals.
- Alaska Airlines, Spirit Airlines, and Boutique Air: Also utilize Terminal B gates.
If you are flying on Delta, you'll head to Terminal A; international carriers like British Airways or Emirates generally use Terminal E.
Parking and Ground Transportation
Choosing where to park or how to arrive depends on whether you're leaving a vehicle or catching a ride.
Terminal B Garage vs. Central Parking
The Terminal B Parking Garage sits directly adjacent to the terminal, offering the shortest walk to check-in counters and gates. If that garage fills up during peak travel holidays, Central Parking serves as the primary alternative, connecting to the terminals via pedestrian bridges on Level 4.
Public Transit and Rideshares
- Silver Line (SL1): This bus service connects every terminal curb directly to South Station in downtown Boston. It is completely free when leaving the airport, making it one of the fastest transit options during rush hour.
- Blue Line: Accessible via the free Massport shuttle (Route 88) from the arrivals curb, the Airport MBTA station connects you rapidly to the subway network.
- Rideshares (Uber/Lyft): Unlike traditional taxis which pick up on the arrivals curb, rideshare pickups are centralized on Level 2 of the terminal parking garage. Follow the dedicated pedestrian signage across the bridges rather than waiting outside baggage claim.
To track local transit schedules and plan your route via public options, consult the Massport Ground Transportation Guide.
Amenities, Dining, and Lounges
Terminal B features a wide array of post-security concessions, ranging from local Boston eateries to quick-serve coffee shops.
- Dining: Most sit-down restaurants, bars, and grab-and-go spots are located after security on both the north and south sides. Options before security are limited, so grab your coffee after scanning your boarding pass.
- Lounges: American Airlines operates an Admirals Club in the southern concourse, and United features a United Club in the northern concourse, giving eligible frequent flyers and club members dedicated workspaces and complimentary refreshments.
- Connectivity: Free high-speed Wi-Fi covers the entirety of Terminal B, alongside numerous stationary charging stations and power pillars near the gate seating areas.
Common Mistakes to Avoid
Travelers frequently run into a few avoidable pitfalls at this hub:
- Entering the wrong pier: Walking into the south entrance when your gate is on the north side means exiting security or taking a long internal trek. Match your gate prefix to the corresponding side before walking inside.
- Misjudging rideshare pickup zones: Looking for your Uber at the arrivals curb results in confusion. Head up to the designated garage pickup zone.
- Assuming all terminals connect airside: While Terminals B, C, and E feature post-security links, Terminal A requires exiting to the street. Keep this in mind if you are meeting someone transferring from another airline.
