Delta Airlines Terminal at Boston Logan Airport (BOS)

Delta Air Lines operates primarily out of Terminal A at Boston Logan International Airport (BOS). All domestic Delta departures, ticketing, check-in desks, and baggage claim facilities are located within Terminal A, which is divided into a Main Concourse (Gates A1 through A11) and a Satellite Concourse (Gates A13 through A22) connected by an underground pedestrian walkway. For international flights arriving without U.S. border preclearance, passengers deplane at Terminal E to complete customs screening before accessing ground transportation.

Boston Logan is Delta's premier Northeast transatlantic hub, offering non-stop flights to major European business centers, Florida holiday spots, and key domestic destinations. Understanding how Terminal A functions ensures a seamless journey through one of the country's oldest and most compact major airports.

Boston Logan Airport Overview: The Role of Terminal A

Boston Logan Airport features four passenger terminals labeled A, B, C, and E. Unlike sprawling airports that require people-mover trains between distant terminals, Logan's layout is compact around a central parking garage:

• Terminal A: Delta Air Lines (main hub carrier) and WestJet.
• Terminal B: American Airlines, Southwest, Air Canada, and United.
• Terminal C: JetBlue and Aer Lingus departures.
• Terminal E: International arrivals requiring customs processing, along with select foreign carriers.

Terminal A offers bright open spaces, streamlined security lines, and modern amenities designed to handle heavy travel between Boston and major commercial centers.

Delta Check-In, Bag Drop, and Ticketing

Delta's passenger processing counters are situated on the second level (Departures) of Terminal A:

• Curbside Baggage Drop: Available along the outer departures roadway for passengers holding electronic boarding documents.
• Self-Service Check-In Kiosks: Located immediately inside the sliding doors, enabling travelers to print boarding passes and baggage luggage tags.
• Main Cabin Bag Drop: Designated drop lanes for standard economy passengers.
• Sky Priority Check-In Area: Dedicated counters offering expedited check-in for Delta One, First Class travelers, and SkyMiles Medallion members.

If you prefer to skip terminal lines entirely, learning how to print your Delta boarding pass at home or saving it to your mobile wallet allows you to proceed straight to TSA screening if you do not have luggage to check.

Terminal A Layout: Main Concourse vs. Satellite Building

Terminal A consists of two distinct physical buildings separated by a tarmac taxi lane:

1. The Main Concourse (Gates A1–A11)

When you clear the central security checkpoint on the second floor of Terminal A, you enter the Main Concourse:

• Gates A1 to A11: Located directly on this level.
• Handles a mix of mainline Delta domestic flights and regional Delta Connection departures.
• Contains retail shopping, casual dining, coffee stands, and a customer service desk.

2. The Satellite Concourse (Gates A13–A22)

If your flight boards from Gates A13 through A22, you must walk to the Satellite building:

• Located past Gate A11, an escalator and elevator bank leads down to an underground climate-controlled moving walkway tunnel.
• Walking through the tunnel takes approximately 3 to 5 minutes.
• The Satellite Concourse houses higher-capacity gates frequently utilized for transcontinental routes, Florida flights, and widebody aircraft.

Because walking to the Satellite building adds several minutes to your journey, checking your gate number on the departure screens before stopping for food in the Main Concourse is strongly recommended.

International Flights: The Terminal E Exception

One of the most important details for international travelers flying Delta through Boston is the distinction between departures and arrivals:

• International Departures: Most Delta international flights depart directly from Terminal A gates. However, select flights or SkyTeam codeshare partners may occasionally board from Terminal E.
• International Arrivals: All Delta international flights arriving from overseas destinations without U.S. customs preclearance (such as flights from London, Paris, Rome, or Amsterdam) arrive at Terminal E.
• Passengers deplane in Terminal E, pass through U.S. Customs and Border Protection, and claim their checked baggage in the Terminal E customs hall.

If you have a domestic connection on Delta after arriving internationally at Terminal E, you must collect your bags, recheck them at the transfer desk outside customs, and take the Massport On-Airport Shuttle bus (Route 11, 22, or 33) or walk via the climate-controlled pedestrian walkways to Terminal A to clear TSA security again.

Delta Sky Club Lounges at Boston Logan

Boston Logan is home to multiple Delta Sky Club locations, giving premium travelers convenient lounge access whether departing domestically or internationally:

• Terminal A Main Concourse Lounge: Located on the third level, directly across from Gate A6 (accessible by elevator). Offers buffet dining, a full bar, private workstations, and runway views.
• Terminal A Satellite Concourse Lounge: Located near Gate A18 in the Satellite building. Features comfortable lounge seating, hot food stations, and bar service.
• Terminal E International Sky Club: Opened in late 2023, this stunning 21,000-square-foot lounge is located near Gate E13. It offers panoramic harbor and skyline views, shower suites, premium dining, and upscale bar selections for transatlantic passengers.

Access is reserved for Delta One passengers, eligible SkyTeam Elite Plus flyers on international itineraries, and qualifying American Express cardholders traveling on same-day Delta itineraries.

Connecting at Boston Logan: Hub Operations

Boston serves as an essential pillar in Delta's hub network, connecting regional cities in New England to the rest of the nation. Compared to the massive distances involved at Delta's Atlanta mega-hub terminal, transferring between gates within Terminal A at Boston is far less physically demanding.

Domestic-to-domestic transfers within Terminal A typically require 35 to 45 minutes of connection time. Even transferring between the Main Concourse and the Satellite Concourse via the underground tunnel takes under ten minutes. If your itinerary involves connections down the East Coast, such as through the Delta terminal at Newark Liberty, you will appreciate Boston's centralized single-terminal gate configuration.

Baggage Claim on Level 1, Terminal A

When arriving in Boston on a domestic Delta flight:

• Deplane at your gate and follow the overhead signs toward "Baggage Claim / Ground Transportation."
• If you arrive at the Satellite Concourse, take the underground walkway back to the Main Terminal building.
• Take the escalators down to Level 1 (Ground Level).
• Checked bags arrive on Carousels 1 through 4.
• The Delta Baggage Service Office is situated adjacent to Carousel 2 to assist with misplaced bags, car seats, or damaged luggage.

Ground transportation—including the MBTA Silver Line bus (which provides free transit into downtown Boston), hotel shuttles, and taxi pickup—is accessible right outside the Level 1 doors. Ride-app pickups (Uber and Lyft) operate from the Central Parking garage, accessible via the pedestrian skybridges on Level 2.

How to Check the Latest Boston Flight Information

To avoid surprises on travel day:

• Check the official Boston Logan Airport Website for real-time security line wait times and parking garage capacities.
• Keep the Fly Delta mobile app updated with push notifications active for gate reassignments and baggage updates.
• Check the electronic Flight Information Display screens positioned throughout Terminal A.
• Remember that winter weather in New England can lead to de-icing delays or ground holds.

What to Do If You Need Help

If your flight is delayed, canceled, or your connection is disrupted at Logan:

• Terminal A Delta Service Centers: Located near Gate A7 in the Main Concourse and near Gate A16 in the Satellite building.
• Gate Agents: Available at the boarding podium prior to departure for seat reassignments or boarding inquiries.
• Independent Phone Assistance: An efficient alternative when airport lines stretch across the concourse during nor'easters or summer thunderstorm disruptions.
