How to Navigate Logan Airport Terminals Like a Pro

Boston Logan Airport is only 3 miles from downtown Boston, but getting around its four terminals can feel confusing for many travelers. Whether you’re landing, leaving, or switching flights, learning the airport layout before you go makes the whole trip much easier and less stressful.

Airport Overview

Boston Logan sits on just 1,700 acres — one of the smallest footprints among the 20 busiest airports in the country — yet it quietly punches above its weight as a major transatlantic hub. It handled 43 million passengers in 2024 alone across four passenger terminals: A, B, C, and E, arranged in a horseshoe shape around a central parking garage, making it a true gateway into New England for both domestic and international carriers.

Terminal-by-Terminal Breakdown

Terminal A — Delta’s Home Base

Terminal A is home to Delta Air Lines, operating as a focus city for one of the airport’s most active domestic and transatlantic routes. If you’ve ever landed here, you’ll notice it runs smoothly — the moving walkways keep the flow steady between the satellite terminal and main concourse. The post-security area connects you without much hassle to the broader Boston Logan network, making it a genuinely calm starting point even during peak hours.

Terminal B — The Busiest Hub

Terminal B sits at the heart of Boston Logan, handling a broad mix of domestic and international travel through carriers like American Airlines, Alaska Airlines, Air Canada, Southwest, United, Spirit, and Boutique Air. Spread across multiple levels, it moves from baggage claim and ground transportation on the lower floors up through ticketing, check-in, and departure gates. The Chase Sapphire Lounge near gates B39–B40 and the Admirals Club near gate B4 give frequent flyers a quieter place to wait before boarding.

Terminal C — JetBlue’s Domestic Hub

Terminal C is JetBlue’s domestic hub at Boston Logan, with Aer Lingus, Cape Air, Etihad, and TAP Air Portugal also calling it home. Directly connected via covered walkways, it stands out for family-forward amenities such as a USO Lounge for active military, children’s play areas near gate C26, and Mamava suites conveniently locatednear every restroom.

Terminal E — The International Gateway

Terminal E serves as Boston Logan’s gateway for international travel, with dedicated immigration and customs processing at the arrivals level — making it the most complex terminal to move through if you’re connecting or departing on a transatlantic route. What many travelers miss is that Terminal E also hosts key lounges like the Emirates Lounge, Lufthansa Lounge, British Airways Galleries Lounge, and the Delta One Lounge, all clustered near gates E11 and E13, so arriving early actually works in your favor here.

Airlines at Logan Airport

Boston Logan serves as a major gateway for both domestic and international carriers, with Delta Air Lines operating as a transatlantic hub from Terminal A and JetBlue using it as a focus city out of Terminal C. You’ll also find American, Spirit, Southwest, United, Alaska, Air Canada, Boutique Air, Cape Air, Silver Airways, TAP Air Portugal, Etihad, British Airways, Lufthansa, Emirates, and Qatar all running regular services — covering 80 domestic and 50 international destinations with over 1,200 daily flights.

Walking Between Terminals

Most travelers don’t realize that Boston Logan’s horseshoe shape quietly dictates how Terminals A, B, C, and E are linked. Some routes flow through covered walkways and moving walkways, while others dip into an underground pedestrian tunnel, and a few require hopping on pre-security shuttle buses or using an airside path through the concourse connector. Understanding this before you land saves a lot of backtracking.

Security and Customs at BOS

Moving between terminals at Boston Logan means potentially exiting and re-entering security — something that can catch you off guard, especially during a tight connection. Each terminal runs its own TSA security checkpoint, and while Terminal B and Terminal C share an airside concourse connector, crossing between others, like Terminal A or Terminal E, happens pre-security, meaning you’ll face screening again.

For international arrivals, Terminal E is where U.S. Customs and Border Protection handles customs, immigration processing, and even pre-clear options depending on your origin — plan for extra buffer time here.

Lounges at Logan Airport

Most travelers rush past the best-kept secret at Boston Logan — the lounges scattered across terminals that can completely change how you experience a layover. Here’s a quick snapshot of what’s available:

• Terminal A: Delta Sky Club at gate A7
• Terminal B: Admirals Club near gate B4, Chase Sapphire Lounge near gates B39–B40
• Terminal C: JetBlue Mint Lounge
• Terminal E: British Airways Galleries, Emirates Lounge, Lufthansa Lounge, Delta One Lounge near gates E11 and E13

Sometimes a day pass is all it takes to get in, and it’s well worth the quiet corner during a long layover.

Parking at Logan Airport

Boston Logan’s Central Parking Garage connects directly to Terminal A via a covered walkway, while pedestrian walkways link across to Terminal B’s parking garage spanning levels 3 to 5. The Central Parking Area off I-90 East feeds straight into the second level of the Terminal B parking garage, making arrivals and departures far less chaotic during peak hours.

Ground Transportation

Getting around Logan Airport doesn’t have to feel like a puzzle. The free On-Airport Shuttle runs 24/7, connecting all terminals with low floors, luggage racks, and wheelchair lifts right at the curbside lower level near Ground Transportation. If you’re heading into downtown Boston, hop on the SL1 MBTA Silver Line BRT from the arrivals level — it cuts through traffic and is one of the smoothest transit moves at any major airport. Uber, Lyft, and taxis handle shorter transfers when timing feels tight.

Airport Facilities Guide

Wi-Fi and Charging Stations

Free Wi-Fi is available across all four passenger terminals at Boston Logan, so whether you’re arriving or departing on domestic or international flights, staying connected is never a concern. Look for charging stations near gates and concourse seating areas throughout Terminals A, B, C, and E.

Lost and Found

If something slips through the cracks during your time at BOS, each terminal runs its own lost and found. Terminal A and Terminal B handle claims near their Level 1 arrivals zones, while Terminal E covers items linked to international arrivals and customs processing areas.

Children’s Play Areas

Traveling with kids through Boston Logan feels far less overwhelming when you know where to stop. Terminal C, around gates C5 to C1,0 offers open seating spaces well-suited for young travelers, and the compact domestic concourse layout makes it easier to keep an eye on them while connecting.

Baby Facilities

Family restrooms are available in Terminal B and Terminal C, with Level 2 being the most accessible floor for parents with strollers. Near ticketing and check-in desks, nursing spaces help manage infant needs between departure and arrival without extra stress.

Traveling With a Pet

The pet relief area in Terminal A on Level 1 near baggage claim is one of the more thoughtfully placed spots at Logan Airport. If you’re working through pre-security with an animal, the pedestrian walkways between terminals give you enough breathing room to settle a nervous pet before reaching your airline’s check-in counter.

Duty-Free Shopping

Duty-free shopping is most concentrated in Terminal E — the primary international terminal — where a well-stocked duty-free store sits near gate E11 on Level 4. Travelers moving through Terminal A can catch another duty-free store close to gate A18 in the satellite concourse on the post-security side.

Prayer 

Boston Logan accommodates passengers of all faiths with interfaith prayer rooms tucked inside the secure area across multiple terminals. Those managing a tight transfer can locate these spaces near Level 2 in Terminal B and Terminal E.

 Currency Exchange 

Foreign currency exchange is most accessible in Terminal E, given its role as the international terminal receiving flights from carriers like British Airways, Lufthansa, Emirates, and Qatar Airways. ATMs are also spread across all terminals near baggage claim on Level 1.

Car Rental

The Rental Car Center is a 5-minute drive from the terminals via the free On-Airport Shuttle, operating 24/7. Whether you land early around 5 a.m. or late after a long international flight, picking up a vehicle doesn’t require fighting traffic or deciphering complicated directions once you step off the arrivals level.

Airport Hotels

There are no on-site hotels physically inside Boston Logan, but several properties within 3 miles along Harborside Drive run a free shuttle service directly to BOS. This is a solid option for travelers facing a pre-dawn departure or landing after the final MBTA Blue Line train at 12:30 a.m.

Navigation Tools

Boston City Ride App

The Boston City Ride app works as a live airport navigation tool, delivering step-by-step directions between terminals, real-time gate updates, and flight status data covering all 1,200 daily flights. It’s most useful during peak morning hours (5–9 AM) when signage alone can’t keep pace with The interactive map on the Logan Airport website gives a clear overhead view of the horseshoe layout — stretching from Terminal A on the eastern side all the way to Terminal E at the north end.  

Final Thoughts

Navigating Boston Logan gets noticeably smoother once you understand that its four passenger terminals sit in a horseshoe shape with well-defined inter-terminal connections. Whether you’re a frequent flyer toggling between Delta Air Lines in Terminal A and JetBlue in Terminal C, or a newcomer leaning on the On-Airport Shuttle and overhead signage, giving yourself extra time and trusting the Boston City Ride app makes moving through one of New England’s busiest airports far more manageable.
