Are you ready to unlock the secrets to a stress-free Southwest check-in experience? Let's dive in!
The Ultimate Guide: How to Check In with Southwest Airlines
Understanding the various check-in options and knowing when to check in can significantly impact your boarding position and overall travel experience. Southwest doesn't assign seats, so your boarding position determines your choice of seat on the aircraft.
Step 1: Understand the Southwest Boarding Philosophy and "The 24-Hour Rule"
Southwest Airlines operates on an open seating policy. This means there are no pre-assigned seats. Instead, passengers are assigned a boarding group (A, B, or C) and a position within that group (1-60+). Your group and position dictate when you board the plane. The earlier you check in, the better your boarding position will likely be, giving you more options for your preferred seat (window, aisle, front, or back) and overhead bin space.
The most crucial detail for Southwest check-in is the 24-hour mark. General online and mobile check-in opens exactly 24 hours before your flight's scheduled departure time. Setting an alarm and checking in promptly at this time is the single most effective way to secure a good boarding position.
-
Pro Tip: If you're traveling with family or friends and want to sit together, checking in precisely at the 24-hour mark is even more important!
Step 2: Choose Your Preferred Check-In Method
Southwest offers several convenient ways to check in, catering to different preferences and situations.

-
How it Works: For an additional fee (which varies by flight), Southwest automatically checks you in 36 hours before your flight's scheduled departure. This is 12 hours before general check-in opens, giving you a significantly better chance of snagging an A or early B boarding position.

Online/Mobile Check-in First (Recommended): Even if you have bags to check, it's still best to complete your online or mobile check-in first to secure your boarding position.

At the Airport:

Self-Service Kiosk (with Bag Tagging): If available at your airport, you can print your bag tags at the kiosk after checking in online. Then, proceed to a designated "Bag Drop" counter.

Bag Drop Counter: Head to the Southwest baggage drop counter (or the main ticket counter) with your checked bags and your boarding pass. A Southwest agent will weigh your bags, apply the tags, and provide you with claim checks.
-
Arrival Time: Allow ample time for baggage check, especially during peak travel periods. For domestic flights, it's recommended to check bags at least 60 minutes before departure. For international flights, allow at least 60 minutes (though 3 hours is often recommended for the overall international process).
-
Step 4: Proceed to Security and Boarding
Once you have your boarding pass (mobile or printed) and your bags are checked (if any), you're ready to head through airport security.
-
TSA Security Checkpoint: Have your boarding pass and a valid government-issued photo ID ready. Follow TSA guidelines for prohibited items and screening procedures.
-
Gate Area: Locate your departure gate. Southwest begins boarding as early as 30 minutes before scheduled departure.

Boarding Process: When your boarding group (A, B, or C) is called, find your designated place in line (indicated by numbered posts at the gate). Board the aircraft in numerical order within your group.
-
Family Boarding: If you're traveling with a child age six or younger, up to two adults traveling with that child can board during Family Boarding, which occurs after the A group and before the B group.

Preboarding: Customers with disabilities who need a specific seat or assistance boarding can preboard. Speak to a Southwest agent at the ticket counter or gate.
