Traveling can be one of life’s greatest pleasures — but long lines at airport security can quickly drain that joy. That’s where TSA PreCheck comes in. This government-run program offers travelers access to expedited security screening at over 200 airports in the U.S., saving time and reducing hassle. If you're flying with Frontier Airlines, you can enjoy these benefits by simply adding your Known Traveler Number (KTN) to your reservation. This guide will walk you through how to add TSA PreCheck to a Frontier Airlines booking step-by-step.

🛫 What is TSA PreCheck?

TSA PreCheck is a program administered by the Transportation Security Administration (TSA) that allows pre-approved travelers to use expedited lanes at security checkpoints. Members don’t need to remove shoes, laptops, belts, or liquids, which significantly speeds up the screening process.

Key Benefits Include:

Shorter wait times
Dedicated TSA PreCheck lines
No need to remove shoes, belts, or light jackets
Keep laptops and 3-1-1 liquids in carry-on bags

TSA PreCheck is available at most major U.S. airports and supported by over 85 airlines, including Frontier Airlines.

✅ Step 1: Enroll in TSA PreCheck

Before you can use TSA PreCheck with Frontier Airlines, you must first enroll in the program and receive your Known Traveler Number (KTN).

How to Enroll:

Visit the TSA Website
Go to tsa.gov/precheck and start the online application.
Complete the Application
Fill out your personal details, including full legal name, date of birth, and contact information.
Schedule an In-Person Appointment
Choose a convenient enrollment center near you. There are over 500 locations nationwide.
Visit Enrollment Center
Bring a valid photo ID and proof of citizenship (like a passport or birth certificate). You'll be fingerprinted and pay an $78 fee (valid for five years).
Receive Your KTN
If approved, you’ll get your Known Traveler Number within a few days (sometimes instantly). You’ll also receive it by mail or email.

✈️ Step 2: Add TSA PreCheck to a New Frontier Airlines Booking

If you’re booking a new flight with Frontier Airlines, you can add your KTN during the booking process:

Visit flyfrontier.com or open the Frontier Airlines app.
Select your flight and begin entering your passenger information.
Look for the field labeled “Known Traveler Number” under your personal details.
Enter your KTN exactly as shown on your TSA PreCheck approval.
Proceed with the booking and confirm your reservation.

Once added, your boarding pass will display “TSA Pre✓” if everything matches.

🔁 Step 3: Add TSA PreCheck to an Existing Frontier Airlines Booking

If you already booked your Frontier flight but forgot to include your KTN, don't worry — you can still add it after booking.

Method 1: Online via “My Trip”

Visit flyfrontier.com
Click on “My Trip/Check-In”
Enter your last name and confirmation code to retrieve your booking
Click “Edit Passenger Information”
Enter or update the Known Traveler Number field
Save the changes

Method 2: Frontier Mobile App

Open the Frontier Airlines app
Go to your booked trips
Select your flight
Tap on passenger details
Add or update your KTN
Save your changes

Method 3: Call Frontier Airlines

If you encounter issues updating your KTN online, call Frontier’s customer service for help.
📞 Customer Support: +1‑833‑341‑3894
Have your booking confirmation number and KTN ready when you call.

👤 Step 4: Save KTN to Your Frontier Miles Profile (For Future Flights)

To avoid re-entering your KTN every time you book a flight, you can save it in your Frontier Miles profile:

Log in to your Frontier Miles account at flyfrontier.com
Navigate to “My Profile” or “Traveler Info”
Find the Known Traveler Number field
Enter your KTN and save the changes

Now, every time you book a flight while logged into your account, your KTN will be automatically added.

✅ Step 5: Confirm TSA PreCheck on Your Boarding Pass

Once your KTN is added, always verify that the TSA PreCheck indicator is included on your boarding pass. It should appear as “TSA Pre✓” in the upper section of your mobile or printed boarding pass.

If it does not appear:

Double-check that your name matches exactly (no typos, same middle name format)
Ensure your KTN was entered correctly
Make sure you saved the changes to your reservation

If the problem persists, call customer support at +1‑833‑341‑3894 for quick resolution.

🔄 TSA PreCheck Tips for Frontier Travelers

Book early: TSA PreCheck info must be synced at least 72 hours before departure.
Match names exactly: Even a small mismatch between your TSA PreCheck application and flight booking can cause issues.
Use the correct KTN: Don’t confuse it with Global Entry or other programs unless it includes TSA PreCheck benefits.
Enroll children under 12 for free: They can use the PreCheck lane with a parent or guardian who is a member.
