You cannot add TSA PreCheck directly through Icelandair, but you can link your Known Traveler Number to your Icelandair frequent flyer account

TSA PreCheck is a separate program you enroll in through the Transportation Security Administration, not through an airline. Once you have your Known Traveler Number (KTN), you then add it to your Icelandair Saga Club account so the airline knows to include it in your boarding pass. Icelandair does not sell TSA PreCheck or handle the enrollment — they only use the number you already have.

The process takes two steps: first, get your KTN from TSA (which involves an process and an in-person appointment), then link that number to your Icelandair account. The linking part takes minutes. The TSA enrollment part takes weeks.

Key Takeaways

  • You must enroll in TSA PreCheck through the TSA website or at an enrollment center before Icelandair can use your number.
  • Once you have your Known Traveler Number, log into your Saga Club account and add it to your profile under "Frequent Flyer Information" or "Travel Documents."
  • The TSA enrollment process costs $78 to $85 and requires an in-person appointment at a TSA enrollment center or approved location.
  • Adding your KTN to Icelandair does not cost anything and takes effect on your next booking after you save the change.

How to enroll in TSA PreCheck before contacting Icelandair

Go to tsa.gov/precheck and click "Enroll Now" to start the process. You will answer questions about your citizenship, criminal history, and traffic violations. The process itself is free and takes about 10 minutes online.

After you submit the process, the TSA will tell you whether you are provisionally approved. If you are, you will receive an email with instructions to schedule an in-person appointment at an enrollment center near you. This appointment costs $78 for five years (or $85 at some locations). During the appointment, a TSA officer will verify your identity, take your fingerprints, and photograph you. The appointment takes about 15 minutes.

Once the appointment is complete, the TSA will mail you a card with your Known Traveler Number printed on it. You can also find your KTN in your TSA PreCheck account online before the card arrives. This is the number you will add to Icelandair.

Where to add your Known Traveler Number in your Saga Club account

Log into your Saga Club account on the Icelandair website. Click on "My Profile" or "Account Settings" (the exact label varies depending on when Icelandair last updated their website).

Look for a section called "Frequent Flyer Information," "Travel Documents," "TSA PreCheck," or "Known Traveler Number." The location changes occasionally, but it is always in the account settings area. Paste or type your 10-digit KTN into the field provided.

Save your changes. The number will appear on your boarding pass the next time you book a flight with Icelandair, as long as you are logged into your Saga Club account when you make the reservation. If you book without logging in, the KTN will not be added to that ticket.

What happens after you add your KTN to Icelandair

Your boarding pass will display your KTN in a special field that TSA agents scan at security. This tells the agent that you have been vetted for TSA PreCheck and are may have access to to use the expedited security lane at U.S. airports.

You will still go through a security checkpoint, but the line is usually shorter and you can leave your shoes, belt, and light jacket on. You can also keep your laptop and liquids in your carry-on bag. Not all U.S. airports have a dedicated PreCheck lane, so check the TSA website for your specific airport before you travel.

TSA PreCheck applies only to U.S. domestic flights and flights departing the United States. Icelandair flights from Reykjavik to the U.S. will benefit from PreCheck when you land in the U.S., but flights within Iceland or to other countries will not use it.

If your Saga Club account does not have a KTN field

Older Saga Club accounts or accounts created before Icelandair added the KTN feature may not display the field in the usual location. Contact Icelandair customer service by phone or through their website chat and ask them to add your Known Traveler Number manually to your account.

Have your KTN ready when you contact them. Icelandair can add it to your account in a few minutes, and it will take effect on your next booking. You do not need to create a new account or re-enroll in anything.

Linking TSA PreCheck to other airlines at the same time

Your Known Traveler Number works with every airline. Once you have your KTN, add it to the frequent flyer accounts of every airline you fly with — not just Icelandair. The process is the same: log into your account, find the KTN or TSA PreCheck field, and enter your number.

If you fly with multiple airlines, you only pay for TSA PreCheck once. The $78 enrollment covers you for five years across all airlines and all U.S. airports. Adding your number to each airline's account is free.

What to do if your TSA PreCheck process is denied

The TSA will tell you the reason for denial in writing. Common reasons include criminal convictions, immigration violations, or false statements on the process. You have the right to request reconsideration or appeal the decision.

If you believe the denial was a mistake, contact the TSA PreCheck program directly through their website or call the enrollment center where you had your appointment. The TSA can sometimes correct errors in background checks or clarify information that was misunderstood.

Frequently Asked Questions

Do I need TSA PreCheck to fly Icelandair to the United States?

No. TSA PreCheck is optional and speeds up security screening, but you can fly without it. You will go through standard security screening instead of the expedited lane. TSA PreCheck is useful if you fly frequently or want to move through security faster.

Can I use my TSA PreCheck number on a flight I already booked?

If you booked before you had your KTN, you cannot add it to that ticket after purchase. You would need to contact Icelandair to see if they can manually add it, but most airlines do not do this. For future bookings, make sure you are logged into your Saga Club account (which now has your KTN saved) when you book.

How long does it take to get my Known Traveler Number?

The online process takes 10 minutes. Scheduling an appointment can take a few days to a few weeks depending on how busy the enrollment center is near you. The in-person appointment takes 15 minutes. After that, the TSA mails your card, which usually arrives within two weeks, though you can see your KTN online when ready after your appointment.

What if I lose my TSA PreCheck card?

You do not need the physical card to use TSA PreCheck. Your KTN is what matters, and it is stored in your TSA account and in your Icelandair Saga Club account. As long as your KTN appears on your boarding pass, you can use the expedited security lane. You can request a replacement card from the TSA if you want one, but it is not required.

Does TSA PreCheck work on connecting flights?

Yes. If you have a connecting flight in the United States, your KTN will appear on both boarding passes (as long as you booked them together and are logged into your Saga Club account). You will go through expedited security at your first airport. At your connection, you may or may not have a security checkpoint depending on the airports and whether you are changing airlines.
