One of the most frequently asked inquiry is How Do You Add TSA PreCheck® to JetBlue? To include TSA PreCheck® for your JetBlue flight, input your Known Traveler Number (KTN) when making the reservation or add it afterward via the "Manage Trips" option on JetBlue's website. Be sure the KTN is also saved in your TrueBlue profile. If processed correctly, the TSA PreCheck® symbol will display on your boarding pass.
