Logan International Airport Terminal B Map (Most Up-To-Date)
Boston Logan’s Terminal B is a wide U-shape wrapped around its parking garage, with two long “sides” joined by the central Great Hall. Think South (American-heavy) vs North (United-heavy), plus a separate B1–B3 pocket that can’t be reached from the main secure concourse. Within Boston’s main airport hub, the far-end walk from one extreme to the other is substantial, so curbside door choice and checkpoint choice matter more here than in most terminals.
Map Table
| Zone | Connection | Walk Time |
|---|---|---|
| B1–B3 pocket | Dedicated B1–B3 screening; no airside tie to main B concourse | Main B concourse unreachable airside |
| South Pier (B4–B39) | Great Hall link; main South checkpoint | Great Hall → mid-pier, ~5–10 min |
| North Pier (B40+) | Airside B↔C connector access; North checkpoint | Great Hall → far North, ~10–15 min |
Logan International Airport Terminal B Map Strategy
- Treat Terminal B as three zones, not one terminal: B1–B3 pocket, South Pier (B4–B39), North Pier (B40+).
- Choose your checkpoint by gate range, not by which check-in counters you see first; the wrong checkpoint can mean a long backtrack or a full re-screen.
- For B1–B3, commit only after you’ve found the dedicated B1–B3 screening entrance; the main South checkpoint can leave you “trapped” away from B1–B3.
- For B↔C↔E walks, start from the North Pier airside connector area near the far-north gates; the connector entrances are easy to miss if you drift landside.

Terminal B remains operational as a “mini-terminal cluster,” with the Great Hall connecting the main South and North piers but not solving the B1–B3 pocket isolation. The airside B↔C connection continues to originate from the far-north United side, while any Terminal A connection stays landside-only until the planned post-security project completes in 2028.

Which exact Terminal B security checkpoint serves your gate area (American/Spirit side vs United/Southwest side), and where is each checkpoint’s landside entrance relative to ticketing?
The wrong checkpoint can force a full exit and re-screen, especially if you’re actually headed to the B1–B3 pocket. South Checkpoint serves the American/Spirit-heavy South Pier (B4–B39), while North Checkpoint serves the United-heavy North Pier (B40+). Southwest is the common trap: check-in can feel “north/central,” but many flights run from the South Pier gates.
| Checkpoint | Serves | Landside entrance placement |
|---|---|---|
| South Checkpoint | South Pier gates B4–B39 (American, Spirit, many Southwest ops) | Adjacent to American-dominant ticketing zone; best curb alignment near Door B204 |
| North Checkpoint | North Pier gates B40+ (United, Air Canada, Alaska) + access toward Terminal C connector | Closest to United-dominant ticketing cluster in the north/center of ticketing |
| B1–B3 dedicated screening | Gates B1–B3 only | Separate entrance from the main South Checkpoint; commit only when signage indicates B1–B3 |
What is the shortest inside-walking route from Terminal B curbside drop-off (Departures) to the correct TSA checkpoint for Gates B20–B39 (United/Southwest pier side)?
The South Checkpoint is the correct screening point for Gates B20–B39, so the shortest route is a curb drop that lands you directly at the American/South side entrance rather than the North/United end. From the wrong end of the U, you can waste 10+ minutes just walking to the checkpoint.
From Level 2 Departures, use a drop near Door B204, enter directly into the American-dominant ticketing area, and keep moving straight toward the South Checkpoint queue. After you clear TSA, turn right into the main retail corridor and continue along the outer curve toward the mid-to-deep South Pier where Gates B20–B39 begin. If you see the Great Hall’s high-ceiling central space first, you’re too far central/north for a “shortest” path.
Where is the dedicated access path for Gates B1–B3 (including its security screening point), and what landmark confirms you’re in the right “B1–B3 pocket” before you commit?
A dedicated B1–B3 screening point is the only correct way into Gates B1–B3, and the main South Checkpoint cannot reach those gates once you’re airside. The access route is a separate, pocket-specific entrance that splits from the main Terminal B South flow, so you must follow B1–B3 signage all the way to its own TSA lane.
The confirming “you’re in the right place” landmark is the pocket’s stripped-down look: a small, isolated holding area with minimal amenities compared to the main South Pier retail corridor. If you can see the main South Pier concessions or feel like you’re entering the big American checkpoint stream for B4+, you are not committing to the B1–B3 pocket entrance and risk getting trapped behind the glass separation.
Can you walk airside from the B1–B3 gate area to the main Terminal B concourses without exiting and re-clearing security—and if so, what is the exact connector path?
No—there is no airside connector from the B1–B3 pocket to the main Terminal B concourses. Gates B1–B3 are an isolated secure “island,” so moving between B1–B3 and the main Terminal B secure area requires exiting to landside and re-clearing security at the correct checkpoint.
If you accidentally clear the main South Checkpoint expecting to reach B1–B3, you’ll hit the glass separation with no airside door through to those gates. The recovery path is to exit the secure area back to the public side, walk to the dedicated B1–B3 screening entrance, and clear TSA again into the pocket.
From Terminal B baggage claim, what is the exact walking path (doors/turns) to the Terminal A shuttle stop used for A↔B transfers?
The Terminal A-bound shuttle stop from Terminal B is on Arrivals Level 1 at the scheduled bus/shuttle curb, using Door B105 (South/American side) or Door B115 (North/United side). Door choice matters because Terminal B is long, and walking to the opposite end adds unnecessary minutes with luggage.
From baggage claim, orient to which side you’re on: if you’re in the American/South baggage claim area, walk straight to the nearest exterior exit marked Door B105, go through the doors to the curb, and look for orange “Scheduled Bus/Shuttle” signage. If you’re in the United/North baggage claim area, do the same to Door B115 and use the corresponding curbside stop. At the curb, verify the bus marquee before boarding because multiple routes stop in the same general bay.
If you must go Terminal B → Terminal A, what is the fastest route choice by layout: indoor walk via garages/walkways vs shuttle—starting from a specific Terminal B door?
Walking landside via the garage skybridges is the fastest B→A option because Terminal A has no airside connection and the shuttle often loops through other terminals first. Starting at Terminal B Departures (Level 2) near Door B204 (South side) keeps you closest to the garage bridges and moving walkways.
| Route | Start point | What happens | Typical time |
|---|---|---|---|
| Indoor walk via garage/skybridges | Level 2 Departures, Door B204 | Cross pedestrian bridge into Terminal B Garage, follow “Terminal A / Central Parking” overhead signs, use skybridge/moving walkways to Terminal A Level 2 | ~8–10 min |
| Shuttle | Level 1 Arrivals, Door B105 or Door B115 | Board terminal shuttle at the scheduled bus curb; route commonly continues B→C→E→A | ~15–25 min |
Where is the airside entrance to the B↔C connector inside Terminal B (nearest gate numbers / landmark), so you don’t accidentally exit to landside?
The airside entrance to the B↔C connector is at the far-north end of Terminal B on the United side, immediately by the Gate B40 area and the Chase Sapphire Lounge. Getting to this point is the key safeguard against accidentally drifting landside, because the connector is not accessed from the South/American pier.
Follow airside signs toward the highest-numbered B gates on the United/North Pier until you are essentially at the terminal’s northern tip. The landmark triangulation is simple: if you are next to the Chase Sapphire Lounge signage and Gate B40, you are at the correct corridor for the enclosed B↔C walkway. If you’re seeing curbside doors, ticketing, or the Great Hall’s landside feel, you’ve exited security and need to get back airside first.
What is the exact airside walking distance from Gate B1 to a reference point in Terminal E (e.g., the E checkpoint or a mid-E gate), using the B–C–E connector?
No airside route exists from Gate B1 because the B1–B3 pocket is isolated from the main Terminal B secure concourse. Reaching Terminal E via the B–C–E connectors requires exiting B1–B3 to landside, then re-clearing security into the main Terminal B secure area (or another connected terminal) before you can walk airside.
| Airside route segment (starting from main Terminal B, near Gate B4) | Landmark to confirm you’re on-route | Distance / time |
|---|---|---|
| Main B secure concourse → far North Pier | Chase Sapphire Lounge / Gate B40 area | ~0.4 mi / 10–12 min |
| B↔C connector | Enclosed corridor at B40 | ~0.15 mi / ~4 min |
| Across Terminal C → C↔E connector | Follow airside wayfinding toward E | ~0.2 mi / 6–8 min |
| C↔E connector → Terminal E checkpoint area | End of connector into E | ~0.15 mi / ~4 min |
| Total (B4-area to Terminal E) | — | ~0.9–1.0 mi / 25–35 min |
Where exactly is Uber/Lyft pickup for Terminal B (level + which interior access point), and which Terminal B side has the most direct walk to it?
Uber/Lyft pickup for Terminal B is in the Terminal B Garage on Level 2 (Departures level), reached by going up from Arrivals and crossing the pedestrian bridge into the garage. Curbside pickup on Level 1 is the common failure point—Ride App pickups are routed into the garage instead.
From the South/American side, the most direct interior access is to go up toward the garage bridge near Door B104 (arrivals-side reference) and then follow “Ride App / TNC” signage once you’re on Level 2 and inside the garage structure. From the North/United side, use the equivalent garage access near Door B113 to reach the Level 2 garage bridge quickly. If you’re already on Level 2 Departures, the move is simpler: enter the terminal, follow signs into the Terminal B Garage, then follow “Ride App / TNC” to the designated pickup area.
Where are the Massport shuttle/bus stops at Terminal B (route identifiers + nearest door/zone), and which stop goes to the MBTA Airport station / rental car center?
Massport terminal shuttles and scheduled buses at Terminal B stop on Arrivals Level 1 at two curbside points: Door B105 on the South/American side and Door B115 on the North/United side. These are the two “decision doors” that keep you from dragging bags the length of Terminal B.
Use Stop B105 (South) if you exit near American/South baggage claim, and use Stop B115 (North) if you exit near United/North baggage claim. Both stop areas can serve multiple routes, so the operational rule is to verify the bus marquee (route number/destination) before boarding. For MBTA Airport station and the rental car center, follow the shuttles specifically signed for those destinations at the scheduled bus/shuttle curb rather than assuming any “terminal loop” bus will take you where you need.
What physical landmark(s) inside Terminal B confirm you’re on the American/Spirit side vs the United/Southwest side before you go through security?
The Admirals Club near Gate B4 is the clearest “American/Spirit side” beacon, while the Chase Sapphire Lounge near Gate B39/B40 is the clearest “United side / far-north” beacon. Those two branded waypoints sit on opposite ends of Terminal B’s secure geography and are much easier to use than gate numbers when you’re moving fast.
On the American-heavy South Pier, the Gate B32 9/11 memorial flag is a definitive confirmation that you’re deep in the American secure zone. On the United-heavy North Pier, being at the extreme north tip by Gate B40 and the Chase Sapphire Lounge signage confirms you’re where the B↔C connector originates. If you’re standing in the high-ceiling Great Hall, you’re in the central hinge between both sides and should choose direction based on your gate range.
If regular TSA is backed up at one Terminal B checkpoint, what is the fastest cross-terminal reposition route to the other checkpoint without getting trapped behind inaccessible barriers?
The fastest safe reposition is a landside walk through the Great Hall ticketing corridor, staying entirely before security, because airside crossovers don’t help you if you haven’t cleared the correct checkpoint yet. The key is to commit early: once you enter a checkpoint queue, backing out can be slower than walking the public corridor end-to-end.
From the South Checkpoint area (American side), step back into the public ticketing hall and walk toward the high-ceiling Great Hall center, then continue to the United-dominant ticketing cluster where the North Checkpoint entrance forms. From the North Checkpoint area, reverse the same public path toward the American-dominant ticketing zone. Do not try to “solve” a B1–B3 assignment by switching between the main South and North checkpoints—B1–B3 requires its dedicated screening entrance, and the wrong security door can create a forced exit-and-reclear recovery.
