While it’s not possible to add PreCheck in the Delta mobile app, you’ll be able to pull up your PreCheck details in the mobile app after adding your KTN to your profile in a web browser.

If you lost your KTN, you can look it up online at https://universalenroll. dhs. gov/workflows?workflow=service-status&servicecode=11115V. [2] X Trustworthy Source U. S.

If you’ve already booked a flight through Delta or a travel service like Expedia or Orbitz, check your existing reservations to make sure your KTN is available. Depending on how you booked your travel, you might need to edit your reservation to add your KTN to each booking.
