So, you've booked your Southwest flight and now you're wondering, just how soon can I check in? It's a great question, especially with Southwest's unique open seating policy, where an earlier check-in generally means a better boarding position and more seat selection options. Let's dive deep into everything you need to know about Southwest Airlines check-in times and how to maximize your chances of getting that coveted "A" boarding group!
Understanding the Southwest Check-In Philosophy
Unlike many airlines that assign seats at the time of booking, Southwest operates on a first-come, first-served boarding system. This means your boarding position (A, B, or C, followed by a number 1-60) is primarily determined by when you check in. The earlier you check in, the lower your number within your boarding group, and the better your chances of snagging that window or aisle seat, or sitting with your travel companions.
How Soon Can You Check Into Southwest Airlines |
Step 1: Mark Your Calendar (Mentally or Physically!) – The 24-Hour Window
Alright, let's get proactive! The most crucial piece of information about checking into Southwest Airlines is this: You can generally check in for your flight starting exactly 24 hours before its scheduled departure time.
This 24-hour mark is your golden window if you want to optimize your boarding position without paying extra. Set a reminder on your phone, a calendar alert, or even a good old-fashioned sticky note! Being ready to check in the moment that 24-hour window opens can make a significant difference in your boarding experience.
Example: If your flight is scheduled to depart on Tuesday at 3:00 PM, you can check in starting Monday at 3:00 PM. Be precise – literally down to the minute!
Sub-heading: Why the 24-Hour Mark Matters So Much
Because Southwest assigns boarding positions based on check-in time (for most passengers), checking in right at the 24-hour mark puts you ahead of those who check in even a few minutes later. This can be the difference between getting an A-group boarding pass and a B or C group.
Step 2: Exploring Your Check-In Options: Online, App, or Airport?
Southwest provides several convenient ways to check in. Choose the one that best suits your travel style and situation.
Sub-heading: Online Check-In (Recommended for Best Boarding Position)
This is hands down the most popular and recommended method for most travelers aiming for an early boarding position.

How to do it:

Look for the "Check In" tab or button.
-
Enter your confirmation number (found on your itinerary) and the first and last name of a passenger on the reservation.
-
Click "Check In" or "Retrieve Reservation."

Follow the prompts to complete the check-in process. You'll then be able to print your boarding pass or save a mobile boarding pass to your device.

Important Note: While you can check in at the airport, it's generally not recommended if you care about your boarding position, especially for popular routes or full flights.

QuickTip: Take a pause every few paragraphs.![]()
-
Passport Verification: For most international flights, you will still need to present your physical passport to a Southwest Customer Service Agent at the ticket counter or a self-service kiosk at the airport for verification before your boarding pass is fully activated or issued.
-
Exceptions: For some international destinations (e.g., Aruba, Havana, Punta Cana), you must receive your boarding pass at the airport. For others, you may be able to scan your passport with your mobile device during check-in. Always double-check Southwest's specific requirements for your international destination.
Sub-heading: Unaccompanied Minors (UMs)
Children traveling as unaccompanied minors (ages 5-11) cannot check in online or via the app.

-
Specific Requirements: Unaccompanied minors are typically only allowed on non-stop or direct flights that don't require a change of aircraft.
Sub-heading: Passengers with Special Needs or Assistance
