How to add TSA PreCheck to Singapore +1-888-760-1051 Airlines booking? Learn simple steps to update your KTN and secure faster screening by for quick assistance.
Travelers flying with Singapore Airlines often look for ways to streamline their airport journey, and adding TSA PreCheck is one of the best steps to make security screening faster and more convenient. TSA PreCheck allows eligible passengers to go through a dedicated expedited security lane, keep shoes and light jackets on, and breeze through screening with fewer hassles. If you’re planning to fly with Singapore Airlines and wondering how to add your TSA PreCheck Known Traveler Number (KTN) to your booking, this detailed guide walks you through every step—from before booking to after check-in.
Understanding TSA PreCheck for Singapore Airlines Flights
Although Singapore Airlines is a foreign carrier, TSA PreCheck is available for its flights that depart from U.S. airports. Whether you’re flying from Los Angeles, San Francisco, New York, Seattle, or any other airport within the U.S., adding your KTN ensures that your boarding pass will reflect TSA PreCheck eligibility.
To enjoy the benefits, however, your KTN must be correctly attached to your reservation well before you arrive at the airport.

1. Add TSA PreCheck While Booking a Singapore Airlines Ticket
One of the simplest ways to include your TSA PreCheck benefits is to add your Known Traveler Number during the reservation process. When booking directly through the Singapore Airlines website or mobile app, you will find an option titled:
• “Passenger Details”
• “Secure Traveler Information”
• or “Known Traveler Number (KTN)”
All you need to do is type in your KTN exactly as issued, ensuring that your name, date of birth, and citizenship information match your TSA PreCheck profile. The system will attach it automatically to your booking.
If you are booking through a travel agency or third-party website like Expedia or Priceline, you can give your KTN to the agent or enter it manually through the site’s secure traveler section.

2. Add TSA PreCheck After Booking Through Manage Booking
If your ticket is already booked and you forgot to enter your KTN, don’t worry. Singapore Airlines allows passengers to update their secure traveler information through the “Manage Booking” section.
Steps to Update Your Booking Online:
1. Visit the Singapore Airlines website.
2. Go to Manage Booking.
3. Enter your booking reference and last name.
4. Open the traveler information tab.
5. Locate the field for KTN (Known Traveler Number).
6. Enter your KTN exactly as provided by TSA.
7. Save the changes.
Once updated, your TSA PreCheck indicator should appear on your boarding pass when you check in for your flight.

3. Call Singapore Airlines Customer Service to Add TSA PreCheck
If you prefer assistance, you can contact Singapore Airlines customer support. The airline’s agents can help add your Known Traveler Number directly to your reservation.
When you call, keep your details ready:
• Full name (must match TSA profile)
• Date of birth
• Passport information
• KTN number
• Booking reference code (PNR)
Customer service can also verify that the number was added successfully.

4. Add TSA PreCheck to Singapore Airlines KrisFlyer Profile
A smart way to ensure your TSA PreCheck appears on all future bookings automatically is to store your KTN in your KrisFlyer account.
Steps to Save KTN in KrisFlyer:
1. Sign in to your KrisFlyer account.
2. Go to your Profile.
3. Select Personal Details or Secure Traveler Information.
4. Add your Known Traveler Number.
5. Save the updates.
The next time you book a flight using your logged-in profile, the system will auto-populate your KTN, reducing the chance of errors or forgetting to enter it.

5. Ensure Your Boarding Pass Shows the TSA PreCheck Indicator
Even if you’ve added your KTN, TSA PreCheck eligibility is only confirmed once your boarding pass displays the appropriate notation. Look for:
• “TSA PRE”
• “TSA PreCheck”
• Or a special PreCheck icon near your name
If your boarding pass doesn’t show the indicator, you can:
• Re-check your KTN
• Re-print or re-download your boarding pass
• Ask an airline agent at the airport to refresh your reservation
A mismatch in your name between your airline ticket and TSA PreCheck profile can also prevent the indicator from appearing, so confirm accuracy ahead of time.

6. Issues That May Prevent TSA PreCheck From Showing Up
Sometimes, even after adding the number, the boarding pass may not reflect PreCheck. Common reasons include:
• Name Mismatch
Your first name, middle name, last name, or suffix differs between your Singapore Airlines ticket and your TSA PreCheck enrollment.
• Wrong KTN
Passengers sometimes confuse their KTN with:
• Redress number
• Global Entry PASSID
• Program membership IDs
Make sure you are using your actual Known Traveler Number.
• Late Entry of KTN
If you add your KTN after checking in, you might need to:
• Cancel check-in
• Re-enter the KTN
• Re-check-in to refresh the system
• TSA Random Exclusions
Even TSA PreCheck members occasionally get randomized checks and may not receive PreCheck on every flight.

7. Adding TSA PreCheck Through Airport Staff
If you were unable to update your booking online, you can request help while checking in at the Singapore Airlines counter. The airline representative can:
• Look up your booking
• Verify identity
• Add your KTN to your Secure Flight data
• Reissue your boarding pass with PreCheck notation (if approved)
This should be considered a backup option, as it’s best to add your KTN at least 24 hours before your flight.

8. Adding TSA PreCheck for Codeshare Flights
Singapore Airlines often partners with other airlines like United Airlines, Alaska Airlines, and JetBlue on connecting itineraries in the U.S. If part of your journey is operated by another carrier, the TSA PreCheck indicator depends on:
• The airline operating the flight
• Whether TSA recognizes that airline for PreCheck benefits
If your first segment is operated by a U.S. carrier, TSA PreCheck is more likely to display properly. Make sure your KTN is added to the operating airline's reservation as well.

9. Can You Add TSA PreCheck for an Award Ticket?
Yes, even award tickets booked using KrisFlyer miles or partner airline miles are eligible for TSA PreCheck. Simply add your KTN through:
• Manage Booking
• KrisFlyer profile
• Customer service
The booking type does not affect TSA PreCheck eligibility.

10. Tips for Ensuring a Smooth TSA PreCheck Experience
To make the process seamless:
• Book using the same legal name as your government ID
• Add your KTN early, ideally during booking
• Save your KTN in your KrisFlyer profile
• Check for TSA PreCheck indicator on your boarding pass before heading to the airport
• Keep your KTN updated if you renew or change your TSA membership
• Arrive early at the airport, especially during peak travel seasons
With TSA PreCheck, your Singapore Airlines security experience becomes less stressful and much faster.

Conclusion
Adding TSA PreCheck to your Singapore Airlines booking is a simple but highly beneficial step. Whether you enter your Known Traveler Number during booking, update it later through Manage Booking, call customer service, or save it to your KrisFlyer profile, the key is ensuring the information matches your TSA account and is added before check-in.
