Understanding Southwest's Open Seating and Boarding Pass System
Southwest Airlines operates differently from most major U.S. carriers, and this difference starts with how boarding passes work. While airlines like Delta, United, and American assign specific seat numbers when you book, Southwest uses an open seating model. This means your boarding pass doesn't show a seat assignment—instead, it shows a boarding group and position number that determines the order in which you board the aircraft.

When you print your Southwest boarding pass, you'll see information like "Group A, Position 23" rather than "Seat 12B." Once you board the plane, you choose any available seat. This system fundamentally changes how boarding passes function and why having one ready before you get to the airport matters considerably.
Southwest assigns boarding groups based on when you check in. Check-in opens exactly 24 hours before your flight's scheduled departure. The earlier you check in during that window, the earlier your boarding group assignment. This is why many Southwest passengers set phone reminders for their check-in time—boarding position directly affects seat quality and overhead bin availability.
The boarding pass itself contains the essential information the gate agent needs: your confirmation number, names of all passengers traveling, your flight details (date, time, route), your boarding group and position, and a barcode that scans at the gate. If you're printing at home, having this document in hand means you can proceed directly to security without stopping at an airline counter.
Practical takeaway: Print your boarding pass after you've checked in online, not before. Checking in first determines your boarding group, and then printing confirms that group assignment on paper for your records.
How to Access Your Boarding Pass Online Before Printing
Before you can print anything, you need to get your boarding pass into your hands—or rather, onto your computer screen. Southwest makes this process straightforward through their website and mobile app. The most direct route to your boarding pass is through Southwest.com, the airline's official website.

Start by visiting Southwest.com and locating the "Check In" section. You'll need your confirmation number (the six-character code you received when you booked your flight) and the passenger's last name. If you have multiple passengers, you can check all of them in at once. Enter these details, and the system will pull up your reservation and show your current booking status.
Once you've checked in successfully—and this is the critical step—your boarding pass becomes available. You'll see your boarding group and position number displayed on screen. At this point, you can view your boarding pass directly in the browser. This digital version shows everything printed versions show: your flight information, confirmation number, boarding group, and position.
Many travelers use the Southwest mobile app instead, which you can download from the Apple App Store or Google Play. Log in with your booking information, navigate to your reservation, and check in there. The app then stores your boarding pass digitally, which some people prefer since they always have it on their phone. However, for printing purposes, accessing through the website often feels more straightforward since you're already on a computer.
The boarding pass remains viewable for 24 hours after you check in. If you check in at 2:00 PM the day before your flight, your boarding pass information stays accessible until 2:00 PM the next day. After that window closes and your flight departs, the information simply expires from the system.
Practical takeaway: Have your confirmation number ready before you start. You can find it in your booking confirmation email, in your Southwest account, or by calling Southwest at 1-800-I-FLY-SWA.
Step-by-Step Printing Instructions for Home Printing
Once you've checked in and your boarding pass appears on your screen, printing is the next logical step. The process works the same way whether you're using a personal printer at home, an office printer at work, or a public printer at a library. Here's what the process looks like in practice.

First, make sure your boarding pass is fully visible on your screen. You should see the complete confirmation information, your boarding group and position clearly displayed, and your barcode (the long stripe of vertical lines on the left side of the pass). This barcode is what the gate agent scans, so it must be clear and undamaged when printed.
Look for a print icon on the Southwest website or boarding pass display—it typically looks like a printer. Click this icon. Your computer will open a print dialog box showing various options. In most cases, you can accept the default settings: standard 8.5 by 11-inch paper, portrait orientation, and normal quality. Southwest boarding passes print reliably with these basic settings.
Before hitting "print," check that your printer is on and has paper loaded. If you're printing from a computer at work or elsewhere, test a page if you're uncertain about the setup. Once you print, the boarding pass should emerge as a single sheet with your information clearly visible. The barcode should scan reliably—it should not be creased, torn, or faded.
If you want a backup (many frequent Southwest flyers do this), you can print a second copy. There's no penalty for having duplicate boarding passes, and some people keep one in their carry-on and one in their wallet. This simple redundancy means if you lose one copy, you still have confirmation of your boarding details.
Some travelers also take a screenshot or photograph of their boarding pass on their phone, just in case. While Southwest won't require this if you have the printed version, having a digital copy means you have options if your printed copy becomes damaged or lost during travel.
Practical takeaway: Verify the barcode is clear and readable before you leave home. If it printed faintly, print again. A clear barcode means no delays at the gate.
Using Mobile Boarding Passes Instead of Printing
Not everyone needs or wants to print their Southwest boarding pass. The airline fully accepts digital boarding passes shown on phones and tablets, and many passengers choose this route exclusively. Understanding how mobile boarding passes work helps you decide whether printing makes sense for your situation.

The Southwest mobile app displays your boarding pass after check-in. Open the app, navigate to your reservation, and you'll see your boarding group and position along with all your flight details. The app generates a barcode that the gate agent can scan directly from your phone screen. This barcode functions identically to a printed barcode—it contains the same information encoded in the same format.
Several advantages come with mobile boarding passes. You don't need a printer, paper, or to remember a physical document. Your phone is something you're carrying anyway. The app can send you notifications about gate changes, delays, or boarding updates, keeping you informed in real time. If your flight is delayed and you want to rebook, you can often do this through the app without leaving your phone.
There are situations where printing still makes sense. If you're traveling with family and checking in multiple passengers, a printed boarding pass for each person can be simpler than having everyone pull out their phones. If you tend to run low on battery during travel days, a printed pass means you don't need to worry about your phone dying. If you're concerned about technical glitches or prefer having a physical backup, printing gives you peace of mind.
Some travelers use a hybrid approach: they check in through the app and display their boarding pass on their phone at the gate. But they also print a copy that they keep folded in their pocket. This covers all scenarios—phone battery dies, the app has an issue, or they simply prefer the tactile confirmation of a paper document.
Southwest's staff can scan mobile boarding passes even if your phone has low battery or connectivity issues, as long as they can see the barcode clearly. If you're concerned about battery life on travel day, consider having your boarding pass printed as a backup.
Practical takeaway: Choose based on your travel habits and comfort level. There's no wrong choice—mobile-only, printed-only, or a combination of both all work with Southwest's system.
Timing Your Check-In and Print for Different Flight Times
The 24-hour check-in window matters significantly for Southwest travel because boarding group assignments depend entirely on when you check in. Understanding how to time this for different flight times helps you strategize for the best boarding position possible.
