Navigating Boston Logan International Airport requires knowing exactly where you're headed before you hit the terminal roadway. Terminal B Logan Airport is split into two distinct structures—Pier B (north) and Pier C (south)—with a parking garage sitting directly in the middle. It primarily serves major domestic carriers like American Airlines and United Airlines, alongside several regional and low-cost operators.
If you're flying out of this hub, your main goal is figuring out how to bypass the congestion, find your gate quickly, and locate the right security checkpoint. This guide breaks down the physical layout, airline assignments, and practical navigation strategies to help you move through the building smoothly.
Terminal Layout and Pier Split
Terminal B isn't just one continuous line of gates. The building is divided into two separate wings—known as Pier B and Pier C—which are separated by a multi-level parking garage.
- Pier B (North): Typically handles operations for carriers like United Airlines. If you check in here, you'll find gates numbered B31 through B38.
- Pier C (South): Generally houses American Airlines, Air Canada, Alaska Airlines, Southwest, and Spirit. Gates range from B4 through B22.
Crucially, these two piers are not connected airside. Once you clear security at Pier B, you cannot walk over to Pier C without exiting and going through security again. Check your boarding pass carefully before joining any queue to ensure you enter the correct security checkpoint for your specific gate.
Airlines Operating in Terminal B
Knowing your airline determines your drop-off zone and ticketing counter. Terminal B hosts several major carriers handling high-volume traffic:
- American Airlines: Check-in counters and gates are primarily located in the southern pier (Gates B4 to B22).
- United Airlines: Operates heavily out of the northern pier, handling both domestic and select international departures.
- Air Canada: Offers domestic and international flights with check-in facilities in Terminal B.
- Alaska Airlines, Southwest Airlines, and Spirit Airlines: Routinely operate out of Terminal B gates, though gate assignments can shift based on airport congestion.
Double-check your airline's app on the day of travel, as Massport occasionally reassigns gates to manage tight schedule windows.
Security Checkpoints and Fast Lanes
Terminal B features dedicated security checkpoints for each pier. Because the two sides are physically separated pre-security, make sure you use the checkpoint corresponding to your gate number.
- TSA PreCheck: Available at both Pier B and Pier C checkpoints, offering expedited screening for eligible passengers.
- CLEAR: CLEAR Plus lanes are active in Terminal B, allowing members to skip standard ID checks. If you have both CLEAR and TSA PreCheck, you can chain them together for the fastest route to your gate.
- Standard Lines: Can back up heavily during morning business travel banks (6:00 AM to 9:00 AM) and Sunday afternoons. Arriving two hours before a domestic flight is standard practice here.
Amenities, Dining, and Lounges
Terminal B offers a solid mix of local Boston flavor and national chains to keep you fed during a layover.
- Dining Highlights: You'll find local staples like Legal Sea Foods, Cisco Brewers, and Kelly's Roast Beef alongside standard coffee shops and grab-and-go kiosks.
- Lounges: United operates a United Club in the northern pier for eligible members and day-pass holders. American Airlines runs an Admirals Club in the southern pier.
Power outlets are available near most gate seating areas, though older sections of Pier C have fewer charging pillars, so packing a portable power bank is smart.
Ground Transportation and Connections
Getting to and from Terminal B depends on your preferred mode of transit.
- Rideshares and Taxis: App-based rideshares (Uber and Lyft) pick up from designated zones on the lower arrivals level. Follow the overhead signs pointing toward "Ride App". Taxis line up right outside baggage claim.
- Public Transit: The MBTA Blue Line connects to the airport via free shuttle buses running from all terminals. The Silver Line (SL1) provides direct service to South Station without requiring a subway transfer.
- Inter-Terminal Shuttles: Free Massport shuttle buses circulate outside the terminals every 5 to 6 minutes if you need to move between Terminal B and Terminals A, C, or E.
You can check official flight statuses and updates directly on the Massport Flight Dashboard before heading out.
Frequently Asked Questions
Can I walk between Pier B and Pier C inside security?
No. Pier B and Pier C are structurally separated. If you enter security on the wrong side, you must exit the secure area, walk outside or through the garage connector, and clear security again.
Where is the animal relief area in Terminal B?
There is an indoor relief area post-security across from Gate B4. Outdoors, you can find a dedicated pet relief patch past door B106 on the lower arrivals level.
Is there a hotel attached to Terminal B?
The Hilton Boston Logan Airport connects directly to the terminal system via sky bridges and walkways, making it easy to walk over if you have an early morning flight or a delayed connection.
How early should I arrive for a flight out of Terminal B?
Arrive at least two hours before domestic departures. Security lines fluctuate drastically depending on the hour, and parking garages fill up quickly during peak holiday periods.
