Runways and air operations at Boston Logan Airport (BOS)
Boston Logan operates six runways with different lengths and orientations, allowing the airport to adapt to variable weather conditions common along the Massachusetts coast, including crosswinds, fog, and rapidly changing weather patterns.
This runway configuration supports operations for regional aircraft, high-rotation narrow-body jets, and wide-body aircraft serving international and transatlantic routes.
Despite being surrounded by water and constrained by limited space, BOS sustains a high volume of daily operations thanks to efficient runway utilization and precise air traffic control procedures.
Longest runway at Boston Logan Airport
Runway 15R/33L, at 10,083 ft, is the longest runway at Boston Logan and plays a critical role in airport operations.
This runway supports wide-body departures at higher takeoff weights, long-haul transatlantic operations, and provides additional operational margins during challenging weather conditions.
A significant portion of BOS’s international traffic depends on this runway to maintain both efficiency and safety.
Boston Logan Airport terminals – Complete breakdown
Boston Logan operates four active passenger terminals, each with a clearly defined operational role.
Terminal A – Delta operations
Terminal A is used primarily by Delta Air Lines. It handles domestic flights and select international services. It is one of the airport’s most modern terminals and is designed for fast, efficient passenger flows.
Terminal B – High-volume domestic operations
Terminal B is one of the airport’s busiest terminals by traffic volume. It is used by multiple airlines, including American Airlines, United, Southwest, Alaska, Spirit, and others. Its layout supports flexible operations and high aircraft turnover throughout the day.
Terminal C – JetBlue’s main base
Terminal C serves as JetBlue’s primary base in Boston and is one of the most active areas of the airport. It handles a high volume of domestic flights along with select international routes, operating at a consistently high tempo.
Terminal E – International terminal
Terminal E is Boston Logan’s international terminal. It is equipped to handle long-haul flights and wide-body aircraft, concentrating services to Europe, the Middle East, and other international markets, along with customs and immigration processing.
Why is there no Terminal D at Boston Logan (BOS)?
Boston Logan does not have an operational Terminal D. The letter D was intentionally omitted from the airport’s terminal scheme and was never assigned as a standalone passenger terminal.
When the current terminal layout was consolidated, airport planners chose to maintain clearly differentiated terminal functions and reserve Terminal E for international operations. As a result, BOS transitioned directly from Terminal C to Terminal E.
There was no terminal removed or renamed. Terminal D simply never existed as part of the official operational design.
Connectivity and airlines at Boston Logan Airport (BOS)
Boston Logan offers strong domestic and international connectivity.
The airport serves more than 100 nonstop destinations, with high-frequency service across the East Coast, Midwest, and West Coast, as well as a robust transatlantic network to Europe and international service to the Middle East, the Caribbean, and Latin America.
JetBlue maintains one of its largest operations at BOS, while Delta uses the airport as a secondary hub for transatlantic flights, reinforcing its strategic role within the U.S. airline network.
Ground access and surface transportation at Boston Logan Airport

This makes BOS one of the closest large airports to its downtown area in the United States.
