A Known Traveler Number (KTN) is used to access TSA PreCheck benefits for quicker airport security screening. JetBlue passengers who are enrolled in a Trusted Traveler Program like TSA PreCheck can add their KTN to their booking or TrueBlue profile. You can update this during booking or afterward by calling 1-800-JETBLUE(1-800-473-6632). Adding your KTN ensures you're eligible for expedited screening where available. You can also log in to your TrueBlue account and save your KTN in the Traveler Profile section to have it applied automatically to future bookings.
