There are two ways to add TSA PreCheck to your Delta Airlines account:
- During the booking process: When you are booking a flight on Delta's website or app, you will be asked to enter your Known Traveler Number (KTN). This is your TSA PreCheck number. If you don't have a KTN yet, you can apply for it on the TSA website.
- After booking: If you have already booked your flight and you have a KTN, you can add it to your Delta account by following these steps:
- Go to the Delta website and log in to your account.
- Click on your name in the top right corner of the page and select "Profile."
- Click on "Secure Travel Info."
- Enter your KTN in the "Known Traveler #" field.
- Click on "Save."
