TSA PreCheck and Its Benefits

TSA PreCheck is a trusted traveler program offered by the Transportation Security Administration (TSA). It provides pre-approved travelers with expedited security screening at participating U.S. airports. Understanding its benefits helps passengers recognize why adding TSA PreCheck to their United reservation is worth the effort.

Key Advantages of TSA PreCheck

• Faster Security Lines: TSA PreCheck passengers typically wait significantly less at airport security checkpoints.

• Minimal Screening: Travelers can leave on shoes, belts, and light jackets while keeping laptops and compliant liquids in carry-on bags.

• Convenient Experience: TSA PreCheck lanes are generally less crowded, providing a stress-free airport environment.

• Consistency Across Airlines: TSA PreCheck eligibility is recognized across multiple airlines, including United, Delta, and American Airlines.

Eligibility Criteria

• U.S. citizens and lawful permanent residents can apply.

• Children 12 and under can accompany eligible adults in TSA PreCheck lanes.

• Applicants must pass a background check, fingerprinting, and an in-person interview.

By understanding these benefits and criteria, travelers can confidently add TSA PreCheck to their existing reservations.

How to Add TSA PreCheck to an Existing United Reservation

Adding TSA PreCheck to your United Airlines reservation requires careful attention to the correct process. Here’s a detailed step-by-step guide to ensure the information is properly integrated into your booking.

Step 1: Confirm TSA PreCheck Enrollment

Before adding TSA PreCheck to your United reservation, ensure that you have an active Known Traveler Number (KTN), which is assigned upon successful enrollment in the program.

• Check Your KTN: If you already have TSA PreCheck, locate your KTN in your enrollment confirmation email or on your membership card.

• Enroll in TSA PreCheck: If you are not enrolled, visit the official enrollment center, complete the application, attend an in-person interview, and receive your KTN.

Step 2: Access Your United Reservation

Once your KTN is ready, you need to update your existing United reservation.

• Via United Website: Log in to your MileagePlus account, navigate to "Manage Reservations," and select the relevant booking.

• Via United Mobile App: Open the app, tap “My Trips,” and select your flight.

• Via Customer Service: If you prefer, contact United Airlines customer support to update your reservation with your KTN.

Step 3: Add Your KTN to Your Reservation

• Locate the field labeled "Known Traveler Number" or "TSA PreCheck" within your reservation details.

• Enter your KTN accurately, ensuring it matches your TSA PreCheck enrollment details.

• Save changes and confirm that the KTN has been applied.

Pro Tip: Double-check your name on the reservation matches the name on your TSA PreCheck enrollment to avoid mismatches, which may prevent TSA PreCheck eligibility at the airport.

Step 4: Verify TSA PreCheck Status on Boarding Pass

• After adding your KTN, check your boarding pass for the TSA PreCheck indicator.

• The boarding pass should display “TSA PreCheck” near the barcode.

• If the indicator is missing, re-confirm your KTN entry or contact United customer service for assistance.

Tips to Ensure TSA PreCheck Works Seamlessly

Adding TSA PreCheck doesn’t always guarantee smooth processing unless travelers adhere to best practices. Below are expert tips to maximize the benefits:

Double-Check Name Matching

Your name on the United reservation must match exactly with your TSA PreCheck enrollment. Middle initials, hyphens, or suffixes should be consistent.

Update Frequent Flyer Accounts

If your TSA PreCheck is not appearing on your boarding pass, ensure your KTN is saved in your MileagePlus account for all future bookings.

Booking New Flights

For new reservations, adding your KTN during the booking process guarantees that TSA PreCheck is automatically included.

Airport Awareness

While TSA PreCheck lanes are faster, some airports may experience occasional delays. Arrive early and confirm the lane is open for your flight.

TSA PreCheck vs. Global Entry

Travelers often wonder about the difference between TSA PreCheck and Global Entry. Understanding these distinctions helps in deciding which program to pursue.

Problem 1: KTN Not Applied

• Solution: Confirm KTN accuracy, update in your MileagePlus profile, or contact United support.

Problem 2: TSA PreCheck Missing on Boarding Pass

• Solution: Ensure the reservation name matches your TSA enrollment. Recheck your KTN entry and request a boarding pass reissue if necessary.

Problem 4: Children Not Showing TSA PreCheck

Travel Documentation
