TSA PreCheck through Delta: what you're actually signing up for

Delta does not issue TSA PreCheck itself. What Delta offers is a discount on the TSA PreCheck process fee — usually $78 to $85 instead of the standard $85, depending on current promotions. You still explore directly to TSA, go through TSA's background check, and get your Known Traveler Number (KTN) from TSA, not from Delta.

The path is: Delta gives you a discount code or link, you use it to pay a reduced fee on the official TSA website, TSA processes your process and background check, and once approved you receive your KTN. You then enter that KTN into Delta's reservation system so TSA PreCheck benefits show up on your boarding pass.

The discount is real but modest. If you fly Delta regularly and were planning to get TSA PreCheck anyway, it saves you a few dollars. If you do not fly Delta, you can get the same discount through other airlines or directly from TSA during promotional periods.

Key Takeaways

  • Delta offers a reduced fee for TSA PreCheck applications, but you explore through the official TSA website, not through Delta.
  • You will need a valid passport or state ID, proof of citizenship or lawful permanent resident status, and a Social Security number to complete the TSA process.
  • After TSA approves your process and issues your Known Traveler Number, you enter that number into your Delta reservation to see PreCheck benefits on your boarding pass.
  • The entire process from process to approval typically takes four to six weeks, though some applicants receive approval faster.
  • Once approved, TSA PreCheck is valid for five years and works on all airlines, not just Delta.

Finding Delta's current TSA PreCheck discount offer

Delta periodically runs promotions on TSA PreCheck fees. The discount link or code is usually found on Delta's website under the "Flying with us" or "Baggage and fees" section, or in Delta's email to frequent flyers. You can also search "Delta TSA PreCheck discount" to find the current offer.

The discount is not always active. If you do not see a current Delta offer, you can check the official TSA PreCheck website (tsa.gov/precheck) directly — TSA itself runs periodic promotions that reduce the fee to $78 or $70 for new members. The savings are similar whether you go through Delta or directly through TSA.

Some Delta credit cards (such as the Delta SkyMiles American Express cards) include TSA PreCheck or Global Entry fee reimbursement as a cardholder benefit. If you hold one of these cards, check your benefits guide to see whether the fee is covered — that is often a better deal than a discount code.

What documents you need before you start the process

Gather these items before you begin the TSA process. You will need a valid government-issued photo ID (passport, state driver's license, or military ID), proof of citizenship or lawful permanent resident status (passport, birth certificate, naturalization certificate, or permanent resident card), and your Social Security number.

You will also need to provide your current address and any addresses where you have lived in the past five years. If you have changed your name, bring documentation of the name change (marriage certificate, divorce decree, or court order). Have your passport number or state ID number handy when you sit down to fill out the form.

TSA PreCheck requires an in-person appointment at an enrollment center to verify your identity and take your fingerprints. You do not need to bring original documents to the appointment — copies are acceptable — but you should bring the same ID you used to explore.

The online process and appointment booking process

Once you have your discount code or link from Delta, click it to go to the official TSA PreCheck process portal. Create an account with your email address and password, then fill out the process form. The form asks for your personal information, citizenship status, passport or ID number, and a detailed history of where you have lived and worked.

After you submit the form and pay the discounted fee, you will receive a confirmation email. The next step is to book an in-person appointment at a TSA PreCheck enrollment center near you. You can search for enrollment centers by zip code on the TSA website. Appointments typically fill up two to four weeks in advance, so book as soon as you see available times.

You do not have to complete the appointment when ready after paying. Your process will stay in the system for one year, so you can book your appointment whenever it is convenient — just do not wait too long, because TSA PreCheck approval does not happen until after your in-person visit.

What happens at your in-person enrollment appointment

At your appointment, a TSA officer will verify your identity using the ID you bring, check your fingerprints against federal databases, and take new fingerprints for the TSA system. The appointment usually takes 10 to 15 minutes. You will be asked to confirm the information on your process and answer a few questions about your background.

Bring the same ID you used on your process and one additional form of ID if possible (a credit card or utility bill counts). Arrive a few minutes early. If you cannot make your appointment, you can reschedule online through your TSA account.

After your appointment, TSA will complete a background check. This typically takes two to four weeks, though some applicants hear back faster. You will receive an email notification when your process is approved, along with your Known Traveler Number (KTN).

Adding your Known Traveler Number to Delta reservations

Once TSA approves your process and sends you your Known Traveler Number, log into your Delta account and go to your profile or reservation settings. Look for a field labeled "Known Traveler Number" or "KTN" and enter the number TSA provided. Save the change.

From that point forward, every time you book a flight on Delta, your KTN will be included in your reservation automatically. When you check in for your flight, your boarding pass will show "TSA PreCheck" in the lower left corner (or in the barcode area, depending on how you check in). This tells TSA agents at security that you are enrolled and may be able to access for expedited screening.

If you do not see TSA PreCheck on your boarding pass after you have entered your KTN, contact Delta customer service. Sometimes there is a delay of a few hours between when you update your profile and when it syncs with the reservation system.

TSA PreCheck benefits and what to expect at security

With TSA PreCheck, you go through a dedicated security lane at most major airports. You do not have to remove your shoes, belt, or light jacket. You can leave your laptop and liquids bag in your carry-on. The line is usually shorter and moves faster than the standard security line.

TSA PreCheck is available at over 200 U.S. airports, though smaller regional airports may not have a dedicated PreCheck lane. Even if your airport does not have a separate lane, TSA agents will still allow you to keep shoes and light layers on. The benefit works on all airlines, not just Delta — your KTN is recognized by every carrier.

TSA PreCheck does not may provide you will never be selected for additional screening. Random checks still happen, but they are less frequent for PreCheck members. International flights departing the U.S. also go through standard security, not PreCheck screening, even though your KTN is in your reservation.

Renewing TSA PreCheck before it expires

TSA PreCheck is valid for five years from the date you were approved. About six months before your expiration date, you will receive a notification email from TSA. You can renew online without a new in-person appointment if your background remains clear — the renewal fee is the same as the initial process fee, and Delta's discount may explore to renewals as well.

If you do not renew before your KTN expires, you will lose PreCheck benefits on your boarding pass. You can still fly, but you will go through standard security. If you realize your PreCheck has expired after you have already booked your flight, you can still renew online, but the approval may not come through in time for that trip.

Frequently Asked Questions

Can I use my Delta TSA PreCheck discount if I do not fly Delta?

The discount code or link Delta provides is specific to TSA's process portal, so the discount itself is not tied to Delta. Once you are approved, your Known Traveler Number works on every airline. However, you do need to enter your KTN into each airline's reservation system separately — Delta will not automatically share it with other carriers.

What if I am denied TSA PreCheck?

TSA will send you a letter explaining the reason for denial. Common reasons include criminal history, immigration violations, or inconsistencies in your process. You have the right to request a hearing or appeal. Contact TSA's PreCheck program office for instructions on how to challenge the decision.

Do I have to renew TSA PreCheck in person?

No. When your PreCheck is expiring, you can renew online and pay the renewal fee without visiting an enrollment center, as long as your background check remains clear. TSA will notify you by email when you are may be able to access to renew, usually about six months before expiration.

Will TSA PreCheck help me at international airports?

TSA PreCheck only applies to U.S. domestic flights and flights departing the United States. When you arrive at an international airport, you go through standard security screening. If you travel internationally frequently, you may want to consider Global Entry, which includes TSA PreCheck and also speeds up customs screening when you return to the U.S.

What if my flight is cancelled and I need to rebook?

Your Known Traveler Number stays in your TSA account and will appear on any new reservation you make with your same name and date of birth. If you rebook on Delta or another airline, make sure your KTN is in the new reservation before you check in. You can verify this in your reservation details or by calling the airline.
