Boston Logan Airport Guide: Terminal E, Connections and Transit

Boston Logan International Airport, Boston, United States: terminals, getting to the city, security, lounges and connections.

Quick answer: Boston Logan has four passenger terminals: A, B, C and E. Terminal E is the main international terminal, and most flights from abroad arrive there for US customs, but international departures can leave from any of the four terminals, so check your airline before you set off. Terminals B, C and E are joined after security; Terminal A is not. The free Silver Line SL1 bus runs from the terminals to South Station, and a free airport shuttle links the terminals to the Blue Line subway.

Facts checked November 2026. Schedules and entry rules change, so confirm with the airline and the official government site before you travel.

Which airlines use which Logan terminal

Terminal A is Delta's base for its domestic flights. Terminal B is used by American Airlines and United, among others. Terminal C is JetBlue's base and is also used by Cape Air and Aer Lingus. Terminal E is the main international terminal and is used by most foreign airlines.

The airport's own advice is that international departures may leave from any of the four terminals. Delta, JetBlue, American and United can run some international flights from their home terminal, while others board in Terminal E. The terminal printed on your boarding pass or shown in the airline app is the one to trust, because Massport notes that assignments can change.

Boston has nonstop flights to more than 60 international destinations, according to Massport. To Paris, for example, Air France, Delta and JetBlue all fly nonstop, as of recent schedules. Check with the airline for the current timetable.

Terminal E: the Boston Logan international terminal

When people search for the Boston Logan international terminal, they mean Terminal E. It has the US Customs and Border Protection hall where most international arrivals are processed, and greeters meet passengers on its first-floor Arrivals level.

Some flights clear US customs before they leave, at a preclearance airport such as Dublin or Shannon. Those flights arrive as domestic flights and can use another terminal, so whoever is collecting you should check the arrival terminal with the airline rather than assume Terminal E.

US citizens and residents can use Global Entry kiosks or the free Mobile Passport Control app to shorten the customs line. Everyone else follows the regular CBP queues.

Connecting at Logan

Terminals B, C and E are connected after security. If both flights are on the same reservation, you can usually walk between them without clearing the TSA checkpoint again, and your airline moves your checked bags.

Terminal A is not connected to the other terminals after security. To get between A and B, C or E you leave the secure area, use the pedestrian walkways or the free On-Airport Shuttle bus, and clear security again. Allow extra time for this, especially at busy morning and evening peaks.

Arriving from abroad and connecting to a domestic flight, you clear passport control, collect your checked bags, clear customs and then drop the bags again for your next flight. On separate tickets, give yourself well over the minimum connection your airline would sell.

The pre-security areas are open 24 hours, but the post-security areas close each night after the last scheduled departure, so an overnight layover on the airside is not an option.

Getting into Boston: Silver Line, Blue Line and more

The Silver Line SL1 bus stops outside every terminal and runs to South Station, where you can change to the Red Line, Amtrak and commuter rail. Boarding SL1 at the airport is free.

For the Blue Line subway, take the free airport shuttle from the terminal curb to Airport station. The Blue Line reaches downtown stops such as State and Government Center in a few minutes once you are on the train.

Logan Express buses run to Back Bay in the city and to park-and-ride sites in Braintree, Framingham, Woburn and Danvers, which suits travellers who live outside Boston. Water taxis cross the harbor to the downtown waterfront, which is a pleasant option in good weather.

Taxis and ride apps are available at every terminal; follow the signs for the pickup areas. Drives into downtown use the Ted Williams or Sumner tunnels, and traffic at rush hour can make the short distance slow.

Lounges by terminal

Terminal E has the widest choice. Delta opened a Delta One Lounge there in December 2024 for its long-haul premium passengers, entered through the Delta Sky Club in Terminal E, and Delta also runs Sky Clubs in Terminal A. Air France, British Airways and Lufthansa each have a lounge in Terminal E for their premium and elite passengers.

In Terminal B, American runs an Admirals Club and United runs a United Club. Massport has said JetBlue plans its own lounge in Terminal C, so check whether it has opened before you count on it.

Entry rules depend on your ticket, airline status, credit card or lounge membership, and they change often. Card programs in particular add and drop lounges, so check the lounge's own page before you travel.

Practical tips for Logan

Airlines generally advise arriving 2 hours before a domestic flight and 3 hours before an international one. Use the FlyLogan app or Massport's security wait times page to check queues before you leave home.

Free Wi-Fi is on the BOSWifi network. Families will find Kidport play areas after security in several terminals, along with nursing rooms and pet relief areas; the FlyLogan app shows the nearest one.

Winter storms can disrupt Boston flights between December and March. On a snowy day, check your flight status before heading to the airport and keep your airline's app handy for rebooking.
