Southwest Airlines Terminal at LaGuardia Airport - Complete 2026 Guide

Quick Answer

Southwest Airlines flies out of Terminal B at LaGuardia Airport (LGA), specifically Pier A, Gates 31A through 35.

Terminal B is the newest and largest terminal at LGA, opened in phases between 2020 and 2022 as part of a $4 billion reconstruction. If you are flying Southwest from New York, this is your building—bright, modern, and significantly less chaotic than the old LGA most travelers remember.

Everything below tells you exactly where to go, how early to arrive, what to eat, and how to get there without the stress.

Terminal B at LaGuardia: Layout and Overview

Terminal B handles the bulk of LGA’s domestic traffic. The building is organized around a central headhouse connected to three piers: Pier A (Gates 1–35), Pier B (Gates 40–59), and Pier C (Gates 60–79). Southwest occupies the far end of Pier A—keep walking past the security checkpoint toward the lower gate numbers until you reach the 31A–35 cluster.

The renovation addressed what was one of the most criticized airports in the country. Terminal B now features wide corridors, abundant natural light through floor-to-ceiling windows, modern seating with power at nearly every seat, and a dining program that does not feel like a punishment.

Orientation tip: After clearing TSA at Terminal B, follow signs for Pier A. Southwest gates are at the end of Pier A. Budget 8–12 minutes of walking time from security to gate if you are moving at a normal pace.

Southwest Check-In at Terminal B

Southwest’s check-in process has a few quirks that catch first-timers off guard. Here is the full breakdown.

Online Check-In (Recommended)

Southwest opens check-in exactly 24 hours before departure. This is not a formality—your boarding position (A, B, or C group) is assigned at check-in, and Southwest does not have assigned seats. The earlier you check in within that 24-hour window, the earlier your boarding group, and the better your seat selection.

Set a phone alarm for T-24 hours. Check in the moment it opens.

EarlyBird Check-In

For $15–$25 per segment, Southwest will automatically check you in 36 hours before departure—before general check-in opens. This almost always guarantees a Group A or early Group B boarding position. For business travelers who want a window seat without the alarm-clock game, it is worth the cost.

At the Airport: Kiosks and Counter

Southwest check-in is on Level 3 (Departures) of Terminal B. Kiosks are available for passengers without checked bags or with pre-paid bags. The full-service counter handles everything else: oversize items, name changes, and paper boarding passes if you need them.

Boarding Groups Explained

• Group A (1–60): Board first, best seat selection

• Group B (1–60): Middle of the plane, still solid choices

• Group C (1–60): Board last, likely middle seats only

• Business Select: Guarantees A1–A15 boarding position

TSA Security at Terminal B

Terminal B has multiple TSA checkpoints. Southwest passengers use the Pier A security lane, which feeds directly into the concourse leading to Gates 31A–35.

TSA PreCheck at Terminal B

PreCheck lanes are available at all Terminal B checkpoints. If you have PreCheck, CLEAR, or Global Entry, use the dedicated lanes—they routinely clear in under 5 minutes even during peak hours.

Wait Time Estimates (2026 averages)

Security tip: Terminal B’s checkpoint lines can stack up fast during the 7–9 AM rush and the late-afternoon business travel surge (3–6 PM). If you are catching a morning Southwest flight, aim to reach the checkpoint by 6:15 AM at the latest.

How Early Should You Arrive for Your Southwest Flight at LGA?

The general guideline Southwest publishes is to arrive 2 hours before domestic departure. For Terminal B at LGA, here is what that actually looks like in practice:

• Checked bags, standard lane TSA: Arrive 2 hours early. No exceptions during peak hours.

• Carry-on only, TSA PreCheck: Arrive 75–90 minutes early. You have margin.

• EarlyBird or Business Select, PreCheck: 60 minutes is workable for most mid-day flights. Not recommended for 6–8 AM departures.

• Connecting through LGA: Add 30 minutes to any estimate above. Terminal connections at LGA require shuttles (see the connecting terminals section below).

Southwest’s final boarding call is typically 10 minutes before departure—this is the “10-minute rule.” Miss that cutoff and you can lose your seat assignment (or in Southwest’s open-seating model, lose your boarding group standing entirely). Bags checked to your destination may continue without you, and rebooking fees apply.

CoreCar recommendation: If you are using a car service or taxi to LGA, build in buffer time for the Van Wyck Expressway, the Grand Central Parkway, and the LGA access road—all three are notorious for unpredictable congestion, especially on weekday mornings and Friday afternoons.

Dining at Terminal B: What’s Actually Worth Your Time

Terminal B’s food program is one of the genuine improvements from the renovation. You are not stuck choosing between a stale pretzel and an $18 beer anymore.

Pre-Security (Level 3 Headhouse)

Limited options here—grab coffee before you enter if you are running late.

Post-Security (Pier A Concourse)

Reality check: Deep Blue Sushi and Biergarten are your best bets for a real sit-down meal. Both are airside (post-security). If your Southwest flight is boarding from Gates 31A–35, plan to be at your gate 25 minutes before departure after a sit-down meal—it is farther from the central dining cluster than you might expect.

Amenities at Terminal B

Wi-Fi

Free Wi-Fi is available throughout Terminal B. Connect to the network “LGA Free Wi-Fi.” No login required, no time limits. Speed is adequate for email and video calls; streaming 4K video is unreliable during peak periods.

Power and Charging

This is where the new Terminal B genuinely shines. Power outlets and USB-A/USB-C charging ports are installed at:

• Nearly every gate seating area in Pier A

• All dining counters and bar seating

• Dedicated charging stations near the main corridors

Bring your own cable. The ports are there; the cables are not.

Seating

Gate seating in Pier A is generous by LGA standards. Upholstered seats with armrests, no coin-operated TV locks, and layouts that allow you to spread out during off-peak hours. Window seating along the concourse provides runway views—not glamorous, but better than a wall.

Shops and Services

Family and Accessibility

• Nursing rooms are available post-security in Pier A

• Family restrooms throughout the concourse

• Accessible paths and elevators on all levels

• Animal relief area pre-security, Level 2

Southwest Baggage Policy: The Biggest Advantage at LGA

This is worth saying plainly: Southwest includes 2 free checked bags for every passenger on every ticket. No fare class requirements. No credit card needed. No membership tier.

At LGA, where Spirit charges for a carry-on and Delta’s basic economy blocks overhead bins, this is a meaningful financial difference—especially for business travelers who check a bag routinely.

Size limits: Checked bags must be under 50 lbs and 62 linear inches. Each passenger may bring one carry-on (fits in overhead) and one personal item (fits under seat in front of you).

Pro tip for business travelers: If you are flying Southwest weekly from LGA, the 2-bag policy alone can save $300–$400 per month versus competitors’ basic economy fares.

Southwest Nonstop Destinations from LaGuardia (2026)

Southwest’s LGA route map focuses on high-demand leisure and business markets. All routes below operate as nonstop from Terminal B.

Note: Southwest’s schedule changes seasonally. Confirm nonstop availability on southwest.com before booking—some routes operate as connecting itineraries during shoulder seasons.

Ground Transportation at Terminal B

Getting to and from Terminal B efficiently is the part of the LGA experience that most travelers underestimate. Here is the honest breakdown.

Car Service (Recommended for Business Travelers)

CoreCar pickup and drop-off is at Terminal B, Level 1 (Arrivals/Ground Transportation level), curbside pickup zone.

For departures: CoreCar drops off at the Departures level (Level 3). Curbside access is available with a commercial vehicle permit—ask your driver to confirm the active drop-off lane for your date, as construction staging occasionally shifts zones.

For arrivals: After collecting your bags (baggage claim is on Level 1), exit through the arrivals doors and look for the designated car service pickup lane. CoreCar drivers track your flight in real time and adjust arrival accordingly. You will receive a “driver is waiting” notification with exact curbside position.

Why car service beats rideshare at LGA:

• Rideshare pickup at LGA requires a 5–10 minute walk to the designated rideshare lot (separate from the curbside zone)

• Surge pricing at LGA can reach 2.5x–3x during peak demand periods

• A pre-booked car service rate is fixed—no surprises after a delayed flight

• CoreCar vehicles can accommodate luggage, including golf bags and oversize items Southwest allows

Book your CoreCar to LGA Terminal B—rates start at a fixed price for the NYC/NJ metro area, no surge pricing.

Taxi

Yellow cabs are available at Terminal B, Level 1. The taxi stand is clearly marked. Metered fare from Midtown Manhattan: approximately $35–$55 plus tolls and tip. From New Jersey: significantly more expensive due to toll structure. From Connecticut: most travelers flying out of LGA from CT find a car service is more cost-effective than a cab.

Uber / Lyft / Rideshare

Rideshare pickup is NOT at the terminal curbside. You must walk to the Central Pickup Facility (CPF), which is a 5–7 minute walk from Terminal B arrivals. Follow the green rideshare signs. Surge pricing applies; during peak Friday afternoon departures, expect significant premiums.

Q70 Limited Bus (Free to Subway)

The MTA Q70-SBS bus runs between Terminal B and the 74th Street/Jackson Heights subway station, connecting to the E, F, M, R, and 7 trains. The ride takes approximately 15 minutes without traffic; 25–30 minutes during peak hours. The bus is free (no fare) and runs every 10–15 minutes.

For Manhattan travelers on a budget or avoiding traffic entirely, the Q70 to the 7 train (Times Square: 20 minutes) is a legitimate option if you have minimal luggage.

Shuttle / Hotel Courtesy Vehicles

Hotel shuttles depart from the Ground Transportation island, Level 1. Look for the hotel board or use your hotel’s app to request pickup. Most major airport-area hotels operate shuttles on a 20–30 minute cycle.

Connecting Between Terminals at LGA

LaGuardia does not have an AirTrain. This is a critical point that catches connecting passengers off guard every single day.

To move between terminals at LGA, you use the free inter-terminal shuttle bus, which runs curbside on the Ground Transportation level (Level 1). The route connects Terminal A, Terminal B, and the Parking Garage.

What You Need to Know

• Terminal C does not exist as a separate building. LGA now operates with Terminal A (Delta Shuttle, regional carriers) and Terminal B (most other carriers, including Southwest). References to “Terminal C” typically refer to the old pre-renovation Concourse C, which has been incorporated into Terminal B’s Pier C. If you see “Terminal C” on an old itinerary or map, you are likely going to Pier C of Terminal B.

• The shuttle does NOT go airside. You must exit security, take the shuttle, and re-clear TSA at the connecting terminal. Add 45–60 minutes minimum for any inter-terminal connection at LGA.

• Walking is not an option between terminals. The roadway layout does not permit pedestrian transit between Terminal A and Terminal B. Use the shuttle.

Terminal B vs. Terminal A: Key Differences

FAQ: People Also Ask About Southwest at LaGuardia

Is Southwest Terminal A or B at LGA?

Southwest Airlines operates from Terminal B at LaGuardia Airport, not Terminal A. Specifically, Southwest uses Pier A, Gates 31A through 35 within Terminal B. Terminal A at LGA is used primarily by Delta Air Lines for its shuttle and mainline operations. Always follow signs for Terminal B when arriving at LGA for a Southwest flight.

How early should I arrive for my Southwest flight at LGA?

Southwest recommends arriving 2 hours before your domestic departure. At LGA specifically:

• With checked bags and no TSA PreCheck: arrive 2 hours early

• Carry-on only with TSA PreCheck: 75–90 minutes is workable for most departures

• During the 7–9 AM peak and 3–6 PM afternoon surge: add an extra 20–30 minutes

Southwest’s check-in counter and bag drop at Terminal B close 45 minutes before departure. If you miss that window, you cannot check a bag.

What airlines are in Terminal B of LGA?

Terminal B is the main domestic terminal at LaGuardia and serves the majority of airlines at LGA, including:

• Southwest Airlines (Pier A, Gates 31A–35)

• American Airlines (Pier B and Pier C)

• United Airlines (Pier B)

• Alaska Airlines (Pier B)

• JetBlue Airways (Pier B / Pier C)

• Spirit Airlines (Pier A / Pier C)

• Frontier Airlines (Pier A)

Terminal A handles Delta Air Lines exclusively (both the Delta Shuttle to Boston/Washington and Delta mainline flights).

What is the difference between Terminal B and C at LaGuardia?

There is no standalone Terminal C at the current LaGuardia Airport. The old LGA had separate terminal buildings labeled A, B, C, and D. The $4 billion reconstruction consolidated most operations into two terminals: Terminal A (Delta) and Terminal B (all other airlines).

What was historically called “Terminal C” is now Pier C within Terminal B—it is physically part of the same building, accessible from the same headhouse after clearing TSA. If your boarding pass shows a gate number in the 60–79 range, you are in Pier C of Terminal B.

Can I walk from Terminal C to B at LGA?

Because “Terminal C” is now Pier C inside Terminal B, there is no inter-terminal walk required—they are the same building. If you need to move between Pier C gates (60s–70s) and Pier A gates (Southwest, 31A–35), you walk through the shared airside corridor after security. No shuttle required, no re-clearing TSA.

If you need to move between Terminal A and Terminal B, you cannot walk—you must take the free inter-terminal shuttle bus. The shuttle runs curbside at Level 1 (Ground Transportation) and connects both terminals.

What is the 10-minute rule for Southwest?

Southwest’s 10-minute rule states that the boarding door closes 10 minutes before the scheduled departure time. If you have not boarded by that cutoff, Southwest may give your seat position to a standby passenger and you risk being left behind.

This rule applies even if you are physically in the gate area. Being at the gate is not the same as being boarded. Southwest agents call final boarding at T-10 and close the door shortly after. At LGA, where Southwest gates are at the far end of Pier A, factor in extra walking time from the nearest restaurant or lounge—it is further than it looks on the map.

Do I still have to check in 24 hours before my Southwest flight?

Yes, the 24-hour check-in rule still applies for Southwest in 2026. Unlike most airlines, Southwest does not assign seats at booking—your boarding position (A, B, or C group) is determined by when you check in during the 24-hour window before departure.

If you check in at exactly T-24, you typically land in Group A or early Group B, which means first choice of seats. If you check in at T-12 or later, expect Group C and a middle seat in the back.

Exceptions:

• EarlyBird Check-In ($15–$25/segment): Southwest checks you in automatically at T-36, before general check-in opens

• Business Select fare: Guarantees A1–A15 boarding regardless of check-in timing

• Southwest Rapid Rewards A-List / A-List Preferred: Automatic priority boarding

What are the carry-on rules for Southwest?

Southwest allows one carry-on bag plus one personal item at no charge on all fares:

• Carry-on bag: Must fit in the overhead bin. Maximum size: 24" x 16" x 10". Standard rollaboards (22" x 14" x 9") fit comfortably.

• Personal item: Must fit under the seat in front of you. Typical examples: laptop bag, backpack, purse, small tote.

What Southwest does NOT do that other airlines do: Southwest does not charge for carry-ons on any fare tier, and they do not block overhead bin access on basic economy tickets. Your carry-on is always free, always included.

Checked bag reminder: Southwest’s 2 free checked bags (up to 50 lbs, 62 linear inches each) remain one of the best policies in U.S. aviation. If you are packing enough to check a bag, Southwest is almost always the better financial choice versus competitors charging $35–$60 per checked bag.

Get to LGA Terminal B Without the Stress

The best travel experiences are the ones you do not have to think about. You know your gate (Pier A, 31A–35). You know your check-in window (T-24, set the alarm). You know where your car is meeting you (Terminal B, Level 1 Arrivals).
