Go to JetBlue's website at least 24 hours before your flight's scheduled departure time and select the "Manage Your Flights" link. Online check-in is not available less than 90 minutes before your departure time. In these cases, obtain your boarding pass at the airport using self-service check-in kiosks or from a JetBlue agent.
Enter the information requested on the JetBlue site, including your first and last name, confirmation number and departure city. Select your seat and the number of bags you intend to check. Confirm your check-in once you have entered all of the requested information by clicking on the "Check In" button.
Print your boarding pass by selecting the box labeled "View Boarding Pass." This option will appear once you complete the check-in process.
Take any checked bags to designated bag drop-off areas at the airport. Your bag-tag numbers will be printed on your boarding pass, which must be presented to the agent at the bag drop-off area. If you do not have checked luggage, go directly to the gate with your boarding pass.
