Complete Southwest LAX Terminal Guide [2026]

Getting through a major airport shouldn’t feel like guesswork. At Los Angeles International Airport (LAX), Southwest Airlines runs all its operations from Terminal 1, and knowing how that terminal works before you arrive makes the whole experience faster and far less stressful. This guide covers the layout, check-in options, bag drop, security, and everything else you need to know about flying Southwest from LAX.

What the Southwest Airlines Terminal at LAX Looks Like

Terminal 1 sits on the north side of LAX and handles all Southwest Airlines departures and arrivals. When you walk in, a wide check-in area greets you with clear signage pointing toward ticketing, bag drop, and boarding gates. Wide walkways keep foot traffic moving and make the space feel manageable even during peak travel hours.

Boarding gates sit toward the rear of the terminal, each with comfortable seating and digital displays showing real-time flight status, boarding times, and gate changes. Charging stations, restrooms, and family-friendly areas are spread throughout, so you don’t have to hunt for them. Dining options and retail shops give you plenty to do while you wait.

Ground transport to Terminal 1 is straightforward. Rideshare pickups and drop-offs use the designated LAX-it lot or the terminal curb depending on current airport policy. The airport’s free shuttle service connects Terminal 1 to nearby parking structures and the other terminals.

How to Check In for Domestic Flights at LAX

Southwest offers three ways to check in for domestic flights: online or via the mobile app, at a self-service kiosk inside Terminal 1, or with a staff member at the check-in counter. Self-service kiosks are the fastest in-person option. Enter your confirmation number or scan your ID, and the kiosk pulls up your flight and prints your boarding pass.

Once you’ve checked in, take your bags to the bag drop area if you have checked luggage. Staff weigh and tag your bags there before sending them off to the aircraft. If you’d prefer face-to-face help, Southwest counter agents are available to assist with any questions throughout the process.

How to Check In for International Flights at LAX

Checking in for an international flight follows the same general steps as domestic check-in, with one key difference: you must present a valid passport and any required visas at the counter. Make sure all your travel documents are ready before you arrive at the airport to avoid delays.

After check-in, international passengers pass through customs and immigration control before reaching their boarding gates. This adds time to your pre-flight routine, which is why a three-hour buffer before departure is strongly recommended. Southwest staff are trained to walk international travelers through documentation requirements and next steps.

How to Use Southwest’s Online Check-In

Southwest’s online check-in system opens exactly 24 hours before your flight’s scheduled departure. For domestic flights, it stays open until 60 minutes before takeoff. For international flights, it closes 90 minutes before departure.

To check in, go to the Southwest website or open the mobile app, then enter your confirmation number, first name, and last name. Once checked in, you can receive your boarding pass by email, text message, or print it at home. You can also choose a seat when availability allows.

Checking in the moment the window opens matters on Southwest flights because the airline uses open seating. Earlier check-in puts you in a better boarding group, which gives you more seat options on the plane.

Bag Drop and Security Check

After you check in — whether online or at the airport — bring any checked bags to the clearly marked bag drop area in Terminal 1. Staff weigh your bags, confirm they meet Southwest’s size and weight limits, tag them, and send them to the aircraft. The process moves quickly when bags are properly packed and within limits.

Next, you’ll go through the security checkpoint. You must present your boarding pass and a valid photo ID before walking through the metal detector and placing carry-on items through the X-ray machine. Terminal 1 uses advanced screening equipment to keep lines moving. TSA PreCheck lanes are available at LAX Terminal 1 for eligible passengers, which can cut your wait time significantly.

Special Assistance Options at the Southwest Terminal

Southwest provides several services for passengers who need extra support. Wheelchair assistance, priority boarding for travelers with mobility challenges, and help navigating through the terminal are all available upon request.

If you think you’ll need any of these services, contact Southwest when you book your ticket or at least 48 hours before departure. Advance notice lets the airline make all necessary arrangements before you arrive. Terminal staff are ready to assist from check-in through boarding.

Lounge and Pre-Flight Comfort Options

Southwest doesn’t run its own airport lounges. Passengers who buy a Business Select ticket get priority boarding and extra Rapid Rewards points, but no dedicated lounge access.

If you want a quieter place to wait, some third-party lounges at LAX accept day passes or credit card memberships. Check your credit card benefits or the lounge’s website before your trip — availability in or near Terminal 1 is more limited than in some of LAX’s other terminals. You can also use the terminal’s regular seating areas, dining spots, and shops while you wait for your flight.

How to Make Your Check-In as Fast as Possible

The single biggest thing you can do is arrive early. Give yourself at least two hours before a domestic flight and three hours before an international one. That window covers check-in, bag drop, security, and any unexpected delays without leaving you rushing to the gate.

Keep your ID, passport (for international travel), and your booking confirmation easy to access before you walk into the terminal. If you checked in online, download your boarding pass to your phone or print it at home. Knowing the terminal layout in advance also saves time — and reduces the stress of hunting for signs when you’re already running on a tight schedule.

What to Do If You Have a Connecting Flight at LAX

When you land at LAX on a Southwest flight with a connection ahead, check the monitors throughout Terminal 1 for your next gate as soon as you deplane. Southwest posts clear signage to guide you between gates.

If your connection involves switching between an international and a domestic flight, budget extra time for the customs and immigration process before you can reach your next gate. When a layover is very short, tell a Southwest staff member right away — they can sometimes help expedite the process. For longer layovers, Terminal 1’s dining and retail options give you a comfortable way to pass the time.
