Navigating Boston Logan International Airport can feel like an exercise in frustration if you don't know your way around, and Terminal B Logan is notorious for catching travelers off guard. Split into two distinct semi-independent wings separated by a central roadway, heading to the wrong side means re-clearing security or taking a long, stressful walk. Whether you're flying out on a business trip or connecting through New England's largest aviation hub, knowing how the terminal operates saves you time and missed-flight anxiety.
Terminal B handles a massive share of domestic traffic, primarily serving major carriers like American Airlines and United Airlines alongside several others. This guide breaks down the terminal's layout, gate configurations, airline split, parking logistics, and essential amenities so you can navigate it like a frequent flyer.
Terminal B Layout and the Two-Side Trap
The single biggest mistake travelers make at Terminal B is getting dropped off at the wrong entrance. The building is divided into a West Side and an East Side, and for many years these two halves were entirely disconnected post-security. While a post-security connector bridge was added during massive modernization projects, walking between the distant ends still takes substantial time.
- West Side (American Airlines & Air Canada): Associated with departure doors B201 through B206. This side manages American's heavy domestic schedule, including mainline flights to major hubs.
- East Side (United, Southwest, Alaska, & Spirit): Associated with departure doors B207 through B215. This wing manages United operations along with other key domestic carriers.
Check your boarding pass for your specific gate number before your rideshare or taxi pulls up to the terminal. Dropping off at door B202 for a United flight means a long trek across the ticketing lobby or an unnecessary trip back outside.
Airline Operations at Terminal B
Terminal B is primarily dedicated to domestic carriers, though some short-haul international flights, particularly to Canada, operate out of its gates.
| Airline | Check-In / Gates Area | Primary Destinations |
|---|---|---|
| American Airlines | West Side | New York (JFK/LGA), Philadelphia, Charlotte, Miami |
| United Airlines | East Side | Chicago (ORD), Denver, San Francisco, Houston |
| Southwest Airlines | East Side | Baltimore, Chicago (MDW), Nashville |
| Alaska Airlines | East Side | Seattle, Portland |
| Spirit Airlines | East Side | Myrtle Beach, Orlando, Fort Lauderdale |
| Air Canada | West Side | Toronto (YYZ), Montreal (YUL) |
If you are transferring from Terminal B to an international flight in Terminal E, you can use the post-security airside bus shuttle or walk through Terminal C, which features airside walkways connecting Terminals B and C.
Security Checkpoints and Wait Times
Each side of Terminal B maintains its own dedicated TSA security checkpoint. Because passenger volume fluctuates heavily during morning business rush hours (6:00 AM to 9:00 AM) and Sunday afternoons, wait times can spike quickly.
- Both checkpoints feature TSA PreCheck lanes for expedited screening.
- CLEAR is available at Boston Logan, though lane locations can change based on ongoing airport construction. Check the official Massport Logan Airport guidelines before you arrive to verify current biometric lane setups.
- Arrive at least two hours before domestic departures to account for check-in lines and unpredictable security queues.
Lounges and Amenities
If you have time to spare before boarding, Terminal B offers several airline lounges and standard airport conveniences, though food options before security are quite limited.
Where to Eat and Drink
Do not count on finding a large sit-down meal in the pre-security check-in areas, which mostly feature grab-and-go coffee counters like Dunkin' or Starbucks. Once you clear security on either the East or West concourses, you will find sit-down bars, local New England seafood spots, and standard airport dining.
Airport Lounges
- American Airlines Admirals Club: Located on the West Side near gate B3. Accessible via club membership, eligible elite status, or qualifying credit card holders.
- United Club: Located on the East Side near gate B24. Offers comfortable seating, work stations, and complimentary snacks and drinks.
- Chase Sapphire Lounge by The Club: Located post-security between gates B39 and B40. This lounge is open to eligible Chase credit card holders and offers high-end dining and cocktail options.
Parking and Ground Transportation
Getting to Terminal B depends on whether you are driving, parking, or taking public transit.
- Terminal B Parking Garage: Dedicated parking is available directly adjacent to Terminal B, providing the shortest walk to the check-in counters. However, daily rates are steep, mirroring the Central Parking Garage cap.
- Logan Express: If you live outside downtown Boston, taking a Logan Express bus from suburban locations like Framingham, Braintree, or Woburn drops you directly at the terminals and avoids airport garage fees.
- Public Transit: The MBTA Blue Line stops at Airport Station, where free Massport shuttle buses pick up passengers and drop them off directly at Terminal B arrivals. Alternatively, the Silver Line (SL1) bus provides free service from South Station straight to every terminal loop.
Frequently Asked Questions
Can I walk between the East and West sides of Terminal B post-security?
Yes. Thanks to previous modernization projects, a secure connector allows passengers to walk between Terminal B North (West) and Terminal B South (East) without exiting security. However, it is still much faster to enter through the correct side initially to avoid a long walk.
Where is the animal relief area in Terminal B?
If you are traveling with a pet, an outdoor relief area is located on the lower level outside door B106. An indoor post-security relief station is also available near Gate B4.
Does Terminal B handle international arrivals?
Most international flights arrive at Terminal E, which houses customs and border protection. However, flights originating from preclearance airports in Canada (such as Toronto or Montreal via Air Canada) arrive directly at Terminal B.
What is the best way to get from Terminal B to downtown Boston without a car?
The Silver Line (SL1) bus is free from the airport and connects directly to South Station, where you can easily transfer to the MBTA Red Line or commuter rail services.
