Navigating Boston Logan International Airport Terminal B doesn't have to be a stressful scramble if you know its layout before you arrive. Terminal B is the busiest domestic terminal at Logan, handling millions of passengers across two distinct halves that aren't physically connected post-security unless you use a specific connector walk. Getting dropped off at the wrong door means a long, frustrating walk or re-entering security, so preparation matters.
The terminal splits cleanly into a West side and an East side. The West side serves American Airlines and Air Canada, while the East side handles United, Southwest, Alaska, and Spirit. Knowing your airline's specific side before your rideshare pulls up saves you from walking half a mile outside or through traffic lanes.
Terminal B Layout and Airline Split
Logan's Terminal B is shaped like a wide U, which traps unprepared travelers who assume all gates connect on the inside. They don't, at least not without paying attention to the split.
The West side features gates roughly numbered B1 through B36, anchored primarily by American Airlines and Air Canada. If you're checking bags for American, aim for the West ticketing desks and doors B201 through B206.
The East side features gates B37 through B43, serving United Airlines, Southwest Airlines, Alaska Airlines, and Spirit. United operates a massive presence here, and its check-in counters sit directly across from doors B207 through B215.
A post-security pedestrian walkway links gate B40 over toward Terminal C, which lets you cross between terminals if you're meeting someone or exploring food options, but you can't walk airside directly from the East gates to the West gates inside Terminal B itself without exiting or using permitted connector routes. Always check your boarding pass for the gate number before clearing security so you pick the right checkpoint line.
Parking and Ground Transportation
Choosing where to park at Logan can dictate how fast you catch your flight. For Terminal B, you have two primary garage options managed by Massport: the Central Garage and the Terminal B Garage.
The Terminal B Garage sits directly adjacent to the building, offering the shortest possible walk to the check-in counters. If you're traveling with heavy bags or small children, this garage cuts down transit time significantly.
The Central Garage sits right in the middle of the airport road network and connects to all terminals via Level 4 pedestrian bridges. It's an ideal choice if you aren't sure of your terminal or want maximum flexibility. Both garages charge the same daily maximum rate of $46, making convenience the primary deciding factor.
For drop-offs and pickups, rideshares like Uber and Lyft pick up in designated central zones or terminal areas depending on current airport directives. Always follow the ground signs for "Ground Transportation" rather than relying solely on app prompts, as Logan frequently updates traffic routing to ease congestion on the lower levels.
Security Checkpoints and Wait Times
Terminal B features two separate security screening checkpoints—one servicing the West side and one for the East side. If you clear security on the East side, you cannot easily walk over to a West-side gate without going back out, so double-check your boarding pass.
Peak departure rushes hit hard between 5:00 AM and 8:00 AM, and again from 4:00 PM to 7:00 PM. During these windows, standard TSA lines can stretch past 20 to 30 minutes. Midday hours between 11:00 AM and 3:00 PM usually see wait times drop under 10 minutes.
If you have TSA PreCheck or CLEAR, dedicated lanes operate on both sides of Terminal B. PreCheck lines move quickly, rarely exceeding 10 minutes even during heavy morning banks. Keep your physical or digital boarding pass handy, as TSA agents at Logan enforce strict document checks before queue entry.
Amenities, Dining, and Lounges
Pre-security options in Terminal B are sparse, consisting mostly of quick coffee counters like Dunkin' on the East side and Starbucks on the West. Don't plan to sit down for a large meal before clearing the checkpoint.
Once you pass security, the options improve dramatically. Both sides offer sit-down restaurants, local seafood spots, and grab-and-go bars.
Terminal B hosts several major airline and credit card lounges:
- Admirals Club: Located on the West side near gate B3, serving American Airlines passengers and eligible club members.
- United Club: Located on the East side near gate B24, offering workspace, snacks, and a full bar.
- Chase Sapphire Lounge by The Club: Located near gates B39 and B40, accessible to Chase Sapphire Reserve cardholders and select Priority Pass members.
Free airport Wi-Fi is available throughout the terminal, and power pillars are scattered near most seating blocks, though they fill up quickly during peak departure banks.
Common Mistakes to Avoid
Travelers frequently stumble over a few avoidable missteps at Logan's Terminal B:
- Entering the wrong checkpoint: Walking into the West checkpoint when your flight departs from an East gate means a frustrating redirection. Check your gate letter and number before getting in line.
- Arriving too late for morning banks: The 6:00 AM departure rush catches many business travelers off guard. Give yourself an extra 15 minutes during early morning hours.
- Hunger before security: Expecting a grand sit-down breakfast in the check-in lobby will leave you disappointed; eat after you clear security.
- Ignoring terminal layout changes: Construction or gate reassignments happen seasonally. Always verify your flight status on the official Massport Logan Airport flight status page before leaving home.
