Southwest Airlines passengers flying from Boston Logan International Airport should go to Terminal B, Pier A. Southwest currently lists gates 31A through 35, but gate assignments can change on the day of travel. Check the Southwest app, your boarding pass, and the airport monitors before heading through security.
Quick Answer
Southwest Airlines operates from Terminal B, Pier A, at Boston Logan Airport, normally using gates 31A–35. Southwest recommends arriving about two hours before departure. Use the Terminal B ticketing area, confirm your gate in the app, and allow extra time during holidays, severe weather, or major Boston events.
Key Takeaways
- Southwest uses Terminal B, Pier A, not Terminal E.
- The airline currently lists gates 31A–35 at BOS.
- Southwest began Boston Logan service on August 16, 2009.
- Southwest now uses assigned seating and boarding groups; open seating is no longer the standard.
- Checked-bag fees apply to many fares, while carry-on and personal items remain free within the airline’s limits.
- Routes and flight frequencies change by season, so confirm the exact itinerary and whether it is nonstop before booking.
Note: Terminal and gate information can change because of construction, irregular operations, or an aircraft swap. The boarding pass and airport display screens should be treated as the final day-of-travel source.
History of Southwest Airlines at Boston Logan
Southwest announced plans to enter Boston Logan in February 2009 and began service on August 16, 2009. The first schedule included 10 daily nonstop flights: five to Chicago Midway and five to Baltimore/Washington. At launch, Southwest used gates E1A and E1B in Terminal E.
The airline later moved its Boston operation. According to Southwest’s current airport information, passengers now check in and depart from Terminal B, Pier A. This history explains why older travel guides still mention Terminal E even though that information is no longer correct.
Southwest has continued to adjust its Boston schedule as demand, aircraft availability, and seasonal travel patterns change. For that reason, old route tables and weekly-frequency claims should not be used for trip planning without checking a current schedule.
Terminal Layout and Amenities for Southwest Passengers
Southwest’s Boston operation is in Terminal B, Pier A. The airline currently lists gates 31A–35. Ticketing and bag drop are on the departures level, while baggage claim and most ground-transportation pickups are on the arrivals level. Follow signs for Terminal B and then confirm the pier and gate on your boarding pass.
Southwest lists airport-provided Wi-Fi, charging stations, self-tagging, a TSA PreCheck Touchless ID checkpoint, and qualifying Priority and Express lanes among the available BOS features. Access to expedited lanes depends on eligibility, operating hours, and the checkpoint in use.
Terminal B also has food, coffee, grab-and-go options, shops, restrooms, seating, and charging points. Hours vary, and some businesses close before the final departure. Travelers with late flights should buy food and drinks before nearby concessions close.
Pro Tip: Do not choose a restaurant based only on “Terminal B.” Logan’s Terminal B has separate areas, and walking time can be longer than expected. Check the airport map and stay on the correct side of security for your gate.
Is There a Southwest Lounge at Logan?
Southwest does not list a dedicated Southwest-branded lounge at Boston Logan. Other lounges may operate in the airport, but access depends on the lounge operator, membership, eligible ticket, or paid-entry rules. Do not assume a lounge is included with a Southwest ticket.
Southwest Routes From Boston Logan
Southwest markets a wide range of itineraries from Boston, including both nonstop and connecting options. Its current Boston booking page highlights cities such as Baltimore/Washington, Chicago Midway, Denver, Nashville, Orlando, Fort Lauderdale, Miami, Fort Myers/Naples, Philadelphia, Milwaukee, Jacksonville, and Pittsburgh.
| Example Destination | Airport | Planning Note |
|---|---|---|
| Baltimore/Washington | BWI | A long-standing Southwest market from Boston; verify current daily frequency. |
| Chicago | Chicago Midway (MDW) | Confirm that you selected Midway, not O’Hare. |
| Denver | DEN | Nonstop availability and frequency may vary by date. |
| Orlando | MCO | Demand is seasonal; school-break dates may be busier. |
| Las Vegas | Harry Reid International (LAS) | Older sources may still use the former McCarran name. |
| Fort Lauderdale | FLL | Check whether the selected flight is nonstop or connecting. |
Southwest also sells BOS-origin itineraries to international destinations. These trips may require a connection, so check the booking result carefully for the “nonstop” label, connection airport, total travel time, passport requirements, and baggage rules. A route being available for sale does not mean Southwest operates a nonstop international flight from Boston.
Warning: Do not rely on an old weekly-flight table. Airline schedules can change several times a year, and a marketed itinerary may include one or more connections.
Check-In, Bags, Seating, and Boarding
When to Arrive
Southwest’s BOS airport page recommends arriving 120 minutes before departure. Two hours is a practical minimum for most trips, but allow more time during holidays, major events, winter weather, or when traveling with children, mobility equipment, pets, or several checked bags.
Southwest’s general deadlines are stricter than the recommended arrival time. Domestic check-in normally closes 30 minutes before scheduled departure, and domestic checked bags must generally be accepted at least 45 minutes before departure. Arriving close to those cutoffs leaves little room for traffic, security lines, or a terminal mistake.
Assigned Seating and Boarding Groups
Southwest ended its traditional open-seating model for travel beginning January 27, 2026. Passengers now receive assigned seats and board by group. Depending on the fare, status, card benefit, or purchased option, a traveler may select a seat in advance or receive one at check-in or the gate.
Once boarding begins, follow the group shown on the boarding pass. Families, passengers needing extra time, military travelers, and other eligible groups should follow the current instructions from the gate agent because boarding order can vary by policy and situation.
Checked Bags and Carry-On Items
Southwest no longer includes two free checked bags with every fare. For U.S. mainland travel booked or changed on or after April 9, 2026, the airline lists standard first- and second-bag charges for Basic, Choice, and Choice Preferred fares, while Choice Extra and certain status or credit-card benefits may include free checked bags. Fees and exceptions can change, so review the baggage page attached to the reservation.
One carry-on bag and one personal item are generally allowed without charge, subject to Southwest’s size, safety, and item rules. Check special restrictions for batteries, sports equipment, pets, child items, and partner-airline itineraries.
Passenger Experience in Terminal B
The most efficient experience starts before arriving at Logan. Check in online or in the Southwest app, review the seat assignment, confirm the terminal, and use digital bag check when available. At Terminal B, self-service kiosks can help eligible passengers print bag tags and complete common check-in tasks.
Free airport Wi-Fi and charging stations can help passengers work or stay connected. Seating near a charging outlet may fill quickly, so bring a charged device and keep a charging cable in the personal item rather than a checked bag.
Families should plan for restroom, snack, and movement breaks before boarding. Travelers who need wheelchair service or other assistance should request it through Southwest in advance and identify themselves to an agent when they arrive.
Tips for Navigating Southwest at Logan Airport
- Enter Terminal B: Do not follow older guides that direct Southwest passengers to Terminal E.
- Confirm Pier A and the gate: Southwest currently lists gates 31A–35, but the boarding pass controls.
- Arrive about two hours early: Add more time for heavy traffic, holiday crowds, severe weather, or checked bags.
- Check in before leaving home: Review the assigned seat, boarding group, bag status, and any schedule change.
- Keep identification and travel documents accessible: Do not pack them in checked baggage.
- Use the correct security checkpoint: Ask an airport employee before joining a long line if the checkpoint does not appear to serve your gate area.
- Watch the monitors: Gate changes can occur even after the boarding pass is issued.
- Plan food purchases: Concession hours vary, especially for early-morning and late-evening flights.
Getting to Terminal B and Parking
Drivers can follow airport signs for Terminal B. The Terminal B Parking Garage provides convenient access, while Central Parking and Economy Parking may also be options depending on availability. Parking can fill during busy periods, so checking availability or reserving in advance can reduce stress.
Massport’s on-airport transportation system connects terminals, parking areas, the Rental Car Center, and the MBTA Blue Line Airport Station. The Silver Line SL1 also serves Logan terminals from South Station. Travelers using public transit should allow extra time for transfers and service disruptions.
Taxi pickup is available at Logan’s arrivals level. Ride-app pickup rules and locations can change by terminal, so follow signs and the instructions shown in the app after landing.
Future Developments Affecting Southwest Passengers
Boston Logan regularly updates terminals, roadways, security areas, concessions, and passenger amenities. However, the reviewed official sources do not confirm a Southwest-specific plan to add gates at Terminal B. Claims about dedicated Southwest expansion should therefore be treated as speculation unless Massport or Southwest announces a project.
Construction and airport-improvement work can temporarily change walking routes, pickup areas, checkpoint access, and concession availability. Check Massport alerts and the Southwest app shortly before travel rather than relying on an old terminal description.
Conclusion
Southwest Airlines currently operates from Terminal B, Pier A, gates 31A–35 at Boston Logan International Airport. The most important steps are to confirm the gate, arrive about two hours early, review current baggage charges, and remember that Southwest now uses assigned seating and boarding groups.
The airline began Boston service in August 2009 at Terminal E, which is why outdated guides still create confusion. For a smoother trip today, follow current Southwest and Massport information, not historical terminal details or fixed route-frequency tables.
Travelers comparing cabin-bag options can also review this guide to the best carry-on luggage for international travel. Always compare the bag’s full outside dimensions, including wheels and handles, with Southwest’s current carry-on rules before flying.
