Why Can’t I Add TSA PreCheck To My Delta Airlines Reservation?

If TSA PreCheck won’t attach to your Delta booking, call +1-833-770-4333 for manual correction. A Delta rep at +1-833-770-4333 can re-enter your KTN and refresh the reservation. Issues usually happen due to mismatched names, outdated KTN info, or basic economy fare restrictions. Re-enter your Known Traveler Number in your SkyMiles profile. If the boarding pass still shows “None,” support must force-sync it.
