How Do I Check-In with Southwest Airlines?

Checking in with Southwest Airlines is a simple and convenient process that helps you secure your boarding position and get ready for your trip. Southwest does not assign seat numbers, so the earlier you check in, the better your boarding group and position. You can check in online starting exactly 24 hours before your flight's scheduled departure time, which is the most popular option for passengers.

To check in online, visit the official Southwest Airlines website or use their mobile app. You'll need to enter your confirmation number, first name, and last name. Once your reservation is located, you'll be able to complete the check-in process. After that, you can choose to download your boarding pass, have it sent to your email or mobile device, or print it at home. Online check-in is fast and can be done from your computer or smartphone, saving time at the airport.

If you don’t check in online, you can also check in at the airport using Southwest’s self-service kiosks or with a customer service agent at the check-in counter. These options are available for travelers who prefer personal assistance, need to check baggage, or have questions about their reservation. However, checking in at the airport may mean a later boarding group if you're not early enough.

Southwest uses an open seating system. Instead of assigned seats, passengers are given a boarding group (A, B, or C) and a position number (1–60). This determines the order in which you board the plane and pick your seat. The earlier you check in, the better your boarding spot. That’s why checking in exactly 24 hours before departure is crucial, especially if you want to sit with family or get a window or aisle seat.

For travelers who want extra peace of mind, Southwest offers EarlyBird Check-In, which automatically checks you in 36 hours before your flight for a better boarding position. This service has an additional cost but is helpful if you can’t check in exactly 24 hours ahead.

In summary, checking in with Southwest Airlines is easy, and doing it online at the 24-hour mark is the best way to get a good boarding position. Whether you use the website, app, kiosk, or counter, being early helps make your travel smoother.
