Boston Logan International is New England's busiest airport, and understanding its four terminals — A, B, C, and E — saves time, stress, and missed flights. Here's how to navigate BOS efficiently.

A quick history of Logan

Logan has been Boston's primary airport since 1923, originally built on landfill in East Boston. Today it serves 40+ million passengers annually across roughly 100 destinations. Unlike large hub airports spread over miles, Logan is compact — terminals are close enough that the inter-terminal shuttle takes 5-10 minutes end-to-end.

Terminal A — Delta's home

Terminal A is the newest of Logan's terminals, opened in 2005 exclusively for Delta Air Lines and Delta Connection partners. It has two concourses (A North and A South) with 22 gates total, a Delta Sky Club, and a dedicated Priority Pass-accessible lounge.

Terminal A is on the south side of Logan, accessed from the Sumner Tunnel and Ted Williams Tunnel. If you're flying Delta, dropoff is almost always faster here than trying to use Terminal E.

Terminal B — American, JetBlue domestic

Terminal B is Logan's largest by gate count, split into B1 (American Airlines, Alaska, Spirit) and B2 (JetBlue domestic, Southwest). It's undergone extensive renovation, with a post-security connector linking B1 and B2 for easier concourse transfers.

If you're flying JetBlue's busier routes — LAX, Fort Lauderdale, San Juan — expect B2 to be the busiest part of Logan, especially early morning.

Terminal C — JetBlue international, United

Terminal C houses JetBlue international flights, United Airlines, Cape Air, Sun Country, and Porter Airlines. It's directly connected to the Hilton Boston Logan Airport hotel, which is useful for same-morning early flights or missed connections.

Terminal E — International arrivals & departures

Terminal E handles all international flights from foreign carriers (British Airways, Aer Lingus, Emirates, Lufthansa, Air France, ANA, and more), plus U.S. international departures from airlines that don't have their own terminal. It's where all international arrivals clear customs, regardless of which carrier flew you in.

Plan extra time for Terminal E — the international security lines tend to be longer, and customs arrivals can take 20-60 minutes during peak times.

Getting between terminals

Logan's free inter-terminal Massport shuttle bus connects all terminals and runs every 5-10 minutes. The walk between Terminal B and Terminal C is short enough to do on foot (about 8-10 minutes), but Terminal A is across the airport and realistically requires the shuttle.

Pickup and dropoff: the insider way

Most first-time Logan visitors try to drive themselves curbside and find it chaotic — the road design encourages moving quickly, and parking attendants enforce no-standing rules. The cell phone lot (on Harborside Drive) is the solution for family pickups: wait there, have your passenger call when they land, then loop to the curbside.

With a private car service, this is automated. Your chauffeur tracks your flight in real time, holds at the cell lot, and arrives curbside at your terminal the moment you're ready.

Parking at Logan

Logan's Central Parking garage is expensive — about $54 per day — but the most convenient. Economy Parking is substantially cheaper (about $18/day) with a shuttle to terminals. For trips over three days, the math often favors a one-way car service over Central Parking.

Local tips most visitors miss

  • The silver line bus from South Station to Logan is free from the airport direction and runs every 8-12 minutes. It takes about 20-25 minutes.
  • Logan Express buses run from Back Bay, Braintree, Framingham, Peabody, and Woburn with frequent service and parking at most terminals.
  • Ted Williams Tunnel (from the south) is usually faster than Sumner Tunnel (from the north) during morning rush, but worse on evening return.
  • Terminal E's international departures level is on the lower roadway — easy to miss if you follow signs without reading carefully.
