Oh, the joys of air travel! We all dream of zipping through security, avoiding those long lines, and keeping our shoes on, right? That's exactly where a Known Traveler Number (KTN) comes in handy, especially when flying with an airline like Southwest. It's your golden ticket to a smoother, faster airport experience with TSA PreCheck.
This comprehensive guide will walk you through every step of adding your KTN to your Southwest Airlines profile and reservations, ensuring you can enjoy those expedited security lanes. Let's get started, shall we?
Understanding Your KTN and TSA PreCheck
Before we dive into the "how-to," let's quickly clarify what a KTN is and why it's so valuable.
What is a KTN? Your Known Traveler Number (KTN) is a unique alphanumeric code assigned to you by the U.S. Department of Homeland Security upon approval for a Trusted Traveler Program. The most common programs that provide a KTN are TSA PreCheck and Global Entry.
What are the Benefits of TSA PreCheck? With TSA PreCheck, you enjoy a streamlined security screening process at over 200 U.S. airports with 90+ participating airlines, including Southwest. This means:
Shorter lines: Spend less time waiting in security queues.
Keep your shoes on: No need to remove your footwear.
Leave liquids and laptops in your bag: No more fumbling with electronics or 3-1-1 compliant bags.
No need to remove belts or light jackets.
Children 12 and under can accompany an enrolled adult.
It's clear that having a KTN is a game-changer for frequent flyers and even occasional travelers looking for a less stressful airport experience.
Step 1: Confirm You Have an Active KTN! (And How to Get One If You Don't)
Are you sure you have a KTN? This might sound obvious, but it's the most crucial first step. If you've been approved for TSA PreCheck, Global Entry, NEXUS, or SENTRI, you will have a KTN. It's typically a 9 or 10-digit alphanumeric code.
Where to find your KTN: You can usually find it on your approval letter, membership card (if applicable), or by logging into your Trusted Traveler Program (TTP) account online.
Engage: If you don't have a KTN yet, stop right here! You'll need to apply for one first. Have you already started the application process, or is this entirely new to you? Let me know, and I can give you a quick overview of how to get one.
Sub-heading: How to Apply for a KTN (TSA PreCheck)
If you're new to the world of expedited security, here's a brief rundown on how to get your KTN through TSA PreCheck:
Online Application: Start by filling out a short online application on the official TSA PreCheck website. This usually takes about 5 minutes. You'll select an enrollment provider (Idemia or Telos) and schedule an in-person appointment.
In-Person Appointment: Attend a quick (often 10-minute) appointment at an enrollment center. Here, you'll:
Verify your identity and provide required documents (e.g., U.S. passport or driver's license plus a citizenship document like a birth certificate).
Have your fingerprints taken for a background check.
Pay the application fee (currently around $78 to $85, valid for 5 years). Many travel credit cards offer a reimbursement for this fee, so check your card benefits!
Receive Your KTN: Once approved, you'll typically receive your KTN via email within 3-5 days, though it can sometimes take up to 60 days. Remember, you can't add a KTN until you have one!
Step 2: Adding Your KTN to Your Southwest Rapid Rewards Account (Recommended!)
This is the easiest and most efficient way to ensure your KTN is applied to all your future Southwest bookings. By adding it to your Rapid Rewards profile, it should auto-populate for any reservations made while logged in.
Sub-heading: Via Desktop Website
Log In: Go to Southwest.com and click on the "Login" button in the top right corner. Enter your Rapid Rewards account number or username and password. If you don't have a Rapid Rewards account, you'll need to enroll first.
Navigate to Your Profile: Once logged in, click on "My Account" in the top right corner, then select "Profile" from the dropdown menu.
Access Traveler Information: Look for a section related to "Traveler Information" or "Add traveler info." It might be under a "Security" or "Preferences" tab.
Enter Your KTN: Locate the field labeled "Known Traveler Number (KTN)" or "TSA PreCheck KTN." Carefully enter your KTN here. Double-check for any typos! Even a single incorrect digit will prevent it from working.
Save Changes: Click the "Save" or "Update" button to confirm your entry.
Sub-heading: Via the Southwest Mobile App
Open and Log In: Launch the Southwest Airlines app on your mobile device and log in to your Rapid Rewards account.
Access Your Profile: Tap the person icon (profile icon) in the top right corner of the screen.
Edit Contact Information: Look for "Edit contact information" or a similar option.
Add/Edit Traveler Info: Tap on "Add / edit traveler info."
Input KTN: Find the "Known Traveler Number" field and carefully enter your KTN.
Save: Tap "Save" to update your profile.
Pro Tip: By saving your KTN to your Rapid Rewards account, any previously booked reservations linked to your account will also be updated with your newly added KTN, and all new reservations booked while logged in will automatically include it. This saves you time and hassle!
Step 3: Adding Your KTN to an Existing Southwest Reservation
What if you've already booked a flight, or even checked in, and forgot to add your KTN? No worries, Southwest makes it relatively easy to add it retroactively.
Sub-heading: For Reservations Not Yet Checked In
Go to Manage Reservations: Visit Southwest.com and click on "Flight" at the top, then "Manage Reservations," or simply go directly to the Manage Reservations page.
Retrieve Your Reservation: You'll need your Confirmation Number (6-character code) and the First and Last Name used for the booking. Enter this information to pull up your flight details.
Locate Traveler Details: Once your reservation appears, look for an option to "Edit Traveler Information," "Add Secure Traveler Information," or similar.
Enter KTN: Find the field for "Known Traveler Number" and carefully input your KTN.
Save and Confirm: Save the changes. You might receive an updated confirmation email.
Sub-heading: For Reservations After Checking In
This can be a bit trickier, but often still possible.
Try Managing Reservation Online/App: First, attempt the steps for "Reservations Not Yet Checked In" above. Sometimes, even after checking in, the system allows for KTN updates.
Re-check In (If Applicable): If you successfully add your KTN, it's often a good idea to re-check in to generate a new boarding pass that reflects your TSA PreCheck status.
Contact Southwest Customer Service: If online methods don't work, call Southwest Airlines directly (1-800-I-FLY-SWA or 1-800-435-9792). Explain that you need to add your KTN to an existing reservation. They can usually update it for you over the phone.
Airport Assistance (Last Resort): As a last resort, you can speak with a Southwest agent at the airport's check-in counter or gate before your flight. They may be able to add the KTN for you, but it's always best to do this beforehand to avoid last-minute stress.
Step 4: Verifying Your TSA PreCheck Status on Your Boarding Pass
After adding your KTN, the most important step is to confirm that it has been successfully applied to your boarding pass.
Digital Boarding Pass: When you check in for your flight (either online or via the app), look for the TSA PreCheck indicator on your digital boarding pass. This is typically a "TSA PRE" or "TSA PreCheck" logo/text printed near your name.
Printed Boarding Pass: If you print your boarding pass at home or at the airport kiosk, ensure the "TSA PRE" indicator is visible.
What if it's not there? Don't panic!
Double-check your KTN: Ensure there are no typos in your KTN in your Southwest profile or reservation.
Name Match: This is crucial. Your name on your Southwest reservation must exactly match the name on your KTN application (including middle names, hyphens, suffixes like Jr./Sr., etc.). Even a slight discrepancy can prevent the PreCheck indicator from appearing. If there's a mismatch, you might need to contact Southwest to adjust your name on the reservation to match your KTN.
Date of Birth: Verify your date of birth is also consistent across both records.
TSA System Randomness: Occasionally, even with a KTN, the TSA system might randomly select you for standard screening. This is rare but can happen.
Contact TSA: If you've confirmed all your details and still no PreCheck, you can contact the TSA directly through their online form or by calling (866) 289-9673.

Here are 10 common questions about adding your KTN to Southwest Airlines, starting with "How to":
How to check if my KTN is active?
You can check the status of your KTN by visiting the TSA's Universal Enroll website and using their "Check My Service Status" tool.
How to ensure my name matches my KTN for Southwest?
Ensure the name on your Southwest Rapid Rewards profile and any flight bookings exactly matches the name you used when applying for your TSA PreCheck/Global Entry. This includes your full legal name, including any middle names or initials.
How to add KTN to a Southwest reservation booked by a travel agent?
If your flight was booked through a travel agent or a third-party website, you might need to contact them directly to add your KTN. Alternatively, you can try managing your reservation on Southwest.com using your confirmation number, or call Southwest customer service.
How to get TSA PreCheck on my boarding pass for international flights with Southwest?
TSA PreCheck benefits are primarily for domestic flights within the U.S. or for the U.S. portion of an international itinerary. If flying internationally, you'll typically still go through standard customs and immigration upon re-entry to the U.S., even if you have Global Entry.
How to update my KTN if it changes or expires?
If your KTN expires or you receive a new one (e.g., after renewal), simply follow Step 2 to update your KTN in your Southwest Rapid Rewards profile. This will ensure future bookings reflect the correct information.
How to know if my whole family can use TSA PreCheck with my KTN on Southwest?
For Southwest and other airlines, children 12 and under traveling on the same reservation as an enrolled adult can use the TSA PreCheck lane. However, individuals 13 and older must have their own KTN for the PreCheck indicator to appear on their boarding pass.
How to get a refund for my TSA PreCheck application fee?
Some premium travel credit cards offer a statement credit for the application fee of TSA PreCheck or Global Entry. Check your credit card benefits guide to see if you're eligible and how to redeem it.
How to troubleshoot if my KTN isn't showing up on my Southwest boarding pass?
First, verify your KTN in your Southwest profile/reservation for typos. Second, ensure your name and date of birth exactly match your KTN record. If issues persist, contact Southwest customer service or TSA directly via their website or customer service line.
How to add a KTN if I've already checked a bag?
Adding a KTN affects your security screening, not your checked baggage process. You can still add your KTN after checking bags, but it's best to do it before heading to the security checkpoint.
How to ensure future Southwest flights automatically include my KTN?
Always add your KTN to your Southwest Rapid Rewards profile. When you book flights while logged into your Rapid Rewards account, your KTN should automatically populate, saving you the hassle of manually entering it each time.
