Updated August 2026
If you are flying Southwest from Boston Logan, go to Terminal B.
More specifically, Southwest currently lists its Boston operation as Terminal B, Pier A, using Gates 31A through 35.
That “Pier A” label can be confusing. It does not mean Terminal A. Southwest is in Terminal B. Pier A is a section of Terminal B.
Quick answer: Southwest Airlines uses Terminal B, Pier A at Boston Logan International Airport (BOS). Southwest currently lists Gates 31A–35. For departures, follow signs for Terminal B and Southwest Airlines. Arriving Southwest passengers claim checked luggage on the Terminal B Arrivals level.

What Terminal Is Southwest Airlines at Boston Logan?
Southwest Airlines is in Terminal B at Boston Logan.
Southwest describes the location as:
- Terminal B
- Pier A
- Gates 31A–35
Logan has four passenger terminals: A, B, C and E. If you are being dropped off, parking, or telling a taxi where you are going, saying simply “Southwest, Terminal B” is the useful part.
Once inside Terminal B, follow the Southwest signs and your boarding pass to the correct gate.
Gate assignments can change, so I would still check the Southwest app or airport monitors on the day of travel rather than walking automatically to Gate 31A because you read it here.
Southwest Is in Terminal B, Not Terminal A
This is worth emphasizing because the terminology invites confusion.
Southwest’s official airport listing says:
Terminal B, Pier A
The word “A” refers to the pier within Terminal B. It does not send you to Boston Logan’s separate Terminal A.
Southwest actually operated from Terminal A years ago, which makes old information on the internet even more confusing. Southwest moved its Boston operation to Terminal B in 2019.
If you find an older travel page telling you to use Terminal A for Southwest at Logan, it is outdated.
Where Is Southwest Check-In at Boston Logan?
For a Southwest departure, go to Terminal B and follow the signs for Southwest ticketing and bag drop.
Southwest currently says its BOS ticket counter is open seven days a week and opens 120 minutes before the first Southwest departure of the day.
If you already have a boarding pass and are not checking baggage, you may be able to proceed directly toward security.
If you need to:
- Check bags
- Use a self-service bag-tagging station
- Speak with a Southwest agent
- Resolve a ticketing issue
allow time at the Southwest counter before going through TSA.
What Gates Does Southwest Use at Boston Logan?
Southwest currently lists Gates 31A through 35.
That puts Southwest in the B30s section of Terminal B.
Boston Logan can change gate assignments as operations require, so the Southwest app and the airport’s departure displays should be your final source on travel day.
Massport also has an interactive Boston Logan airport map that is useful if you want to see the terminal layout before arriving.
How Early Should You Get to Logan for a Southwest Flight?
Southwest currently recommends arriving at Boston Logan 120 minutes before departure.
That is also consistent with Massport’s general recommendation of two hours for domestic departures.
I would consider arriving earlier when:
- You are checking bags
- You are traveling during a holiday period
- You have an early-morning rush departure
- You are traveling with children or a large group
- You need special assistance
- Weather or construction is complicating airport access
Massport publishes live estimated TSA security wait times, which are worth checking before leaving for the airport.
If your itinerary involves international travel, Massport recommends allowing three hours. Follow the more conservative recommendation when it applies to your trip.
Does Terminal B Have TSA PreCheck?
Yes. Terminal B has TSA screening for passengers departing from the terminal, and Southwest currently lists TSA PreCheck among the amenities available at BOS.
Security arrangements and checkpoint hours can change during the day, so use the airport’s live wait-time information rather than assuming every checkpoint or expedited lane is open whenever you arrive.
Where Is Southwest Baggage Claim at Boston Logan?
If you arrive in Boston on Southwest and checked a bag, stay in Terminal B and follow signs for Baggage Claim and Arrivals.
Massport says baggage claim areas are located on the Arrivals level of each terminal.
Your carousel is not permanently tied to one Southwest gate or flight. Check the monitors in the baggage-claim hall for the carousel assigned to your flight.
If your checked bag does not arrive, Southwest asks customers to report the problem to its Baggage Service Office in the baggage-claim area or at the ticket counter. Southwest also provides an online reporting option after you leave the airport.
Where Should Someone Drop You Off for Southwest?
Tell the driver:
Boston Logan, Terminal B, Southwest Airlines.
Follow the airport signs for Terminal B Departures.
Massport permits free curbside passenger drop-off at all Logan terminals. There is no reason to drive to Terminal A simply because Southwest calls its section of Terminal B “Pier A.”
Where Do You Pick Up a Southwest Passenger?
Southwest arrivals use Terminal B.
Massport directs drivers picking up arriving passengers to the Arrivals level of the appropriate terminal.
So if you are meeting someone arriving on Southwest:
- Follow signs for Terminal B.
- Choose Arrivals rather than Departures.
- Have the passenger tell you which door or pickup location they are standing near.
Logan can become extremely congested, so waiting until the passenger has actually collected bags and reached the curb can save an unnecessary loop around the airport.
Where Is Uber or Lyft at Terminal B?
Ride-app arrangements at Logan are different from ordinary curbside pickup.
Massport currently directs Terminal B Uber and Lyft pickup and drop-off to Level 2 of the Terminal B Parking Garage.
Follow signs in the terminal for Ride App or the Terminal B garage rather than simply walking outside to the normal Arrivals curb and expecting the car to meet you there.
Check Massport’s current Uber and Lyft instructions because airport ride-app arrangements can change.
How Do You Get From Southwest’s Terminal B to Another Logan Terminal?
Boston Logan has several ways to move between terminals.
Terminal B to Terminal C or E
Massport says Terminals B, C and E are connected post-security.
That is useful if you are connecting between flights and do not have a reason to leave the secure area.
You can follow terminal-connection signage rather than automatically exiting security and boarding a bus.
Terminal B to Terminal A
Terminal A is different.
Massport is building a new secure-side Terminal A–B connector, but until that connection is available for your trip, passengers moving between A and B may need to use the landside pedestrian route or Logan’s airport shuttle and then clear security again.
Check the current airport map and signage if your itinerary requires this transfer.
The airport shuttle
Massport operates a free on-airport shuttle connecting Terminals A, B, C and E as well as other airport transportation points.
That is the simplest fallback if you are outside security and need to reach another terminal.
What If You Are Connecting From an International Flight?
Most international arrivals at Boston Logan use Terminal E because that is where U.S. Customs and Border Protection processes arriving passengers.
There are exceptions for flights that clear U.S. Customs before departure overseas.
If you arrive internationally at Terminal E and then connect to a Southwest flight:
- Clear U.S. immigration and customs as required.
- Collect checked luggage when required.
- Follow signs toward your connecting terminal.
- Go to Terminal B for the Southwest flight.
- Recheck baggage if necessary and clear TSA security again.
Do not go to Terminal E for your outbound Southwest flight merely because the overall itinerary is international. Southwest’s official Boston airport listing is Terminal B.
International departures at Logan can technically leave from several terminals, so your boarding pass remains the final authority.
Getting Between Southwest and Downtown Boston
Boston Logan is unusually close to downtown, and public transportation is often practical.
Silver Line SL1
The MBTA Silver Line SL1 serves Logan’s passenger terminals and connects the airport with South Station.
Travel on the SL1 from Logan into Boston is free.
South Station connects with the Red Line, commuter rail and Amtrak, making the Silver Line particularly useful if your destination is downtown, Cambridge via the Red Line, or another transit-connected neighborhood.
Blue Line
The MBTA Blue Line does not stop directly beneath Terminal B.
Instead, take one of Massport’s free airport shuttle buses from the terminal to Airport Station on the Blue Line.
The Blue Line is useful for downtown stops including Aquarium and State, and for connections to the Orange and Green Lines.
Massport’s current public-transportation instructions are available at Getting to Logan by public transportation.
Parking for a Southwest Flight
If you are driving yourself, the Terminal B Parking Garage is the most convenient airport parking for Terminal B.
There are other Logan parking options, including Central Parking and Economy Parking, but the Terminal B garage minimizes the amount of airport navigation between the car and Southwest.
Parking availability can change during busy periods. Check Massport’s current parking status before leaving home if you plan to park at the airport.
Where Does Southwest Fly From Boston?
Southwest’s Boston route network changes with season and demand, so I would not rely on an old static destination list.
Southwest currently markets flights from Boston to cities including Baltimore/Washington, Chicago Midway, Nashville, Denver, Orlando, Fort Lauderdale, Tampa, Dallas, Los Angeles and a number of other destinations and connecting markets.
The important word is currently. Some routes operate only on certain days or seasons, and not every destination Southwest sells from Boston is necessarily a nonstop flight.
Use Southwest’s current flights-from-Boston page to see schedules for your actual travel dates.
The older version of this Flight Wisdom article listed seven nonstop destinations. That snapshot is no longer a useful way to describe Southwest’s Boston operation because airline schedules change far too often.
Is Southwest’s Boston Terminal Good for Connections?
Terminal B works particularly well for connections involving airlines in Terminals B, C and E because those terminals now have post-security connections.
But be careful with separately booked tickets.
If you buy one Southwest ticket and an unrelated ticket on another airline, the carriers may not protect you if the first flight runs late and you miss the second one. Checked bags may also need to be collected and rechecked.
A physically easy airport transfer does not turn two separate tickets into one protected itinerary.
Southwest at Boston Logan: What I Would Remember
If you remember only four things, make them these:
- Southwest is in Terminal B.
- Pier A does not mean Terminal A.
- Southwest currently uses Gates 31A–35.
- Check the app on travel day because gates and airport operations can change.
That solves the main problem most travelers have when searching for Southwest at Boston Logan.
