JetBlue offers credit cards in partnership with Barclays, such as the JetBlue Plus Card. While these cards offer great travel rewards, they do not automatically include a statement credit for TSA PreCheck or Global Entry like some premium travel cards do. However, you can still apply for TSA PreCheck separately and use your JetBlue credit card for the payment, though you won't receive a reimbursement. Some limited-time offers may occasionally include TSA PreCheck perks, so check with Barclays for the most current card benefits. If you're looking for cards with travel security perks, consider comparing with other travel credit cards. For assistance with TSA PreCheck and card benefits, call JetBlue support at 1-808-865-4114.
