JetBlue allows passengers to check in for their flights starting 24 hours before the scheduled departure time. The easiest way to check in is online through the JetBlue website or mobile app. To complete online check-in, you need to enter your booking confirmation code, ticket number, or TrueBlue account number along with your last name. This process lets you confirm your flight details, select or change your seat if available, and add checked baggage or other services. Online check-in remains open until 40 minutes before domestic flights depart and until 60 minutes before international flights leave. If you are traveling only with carry-on luggage, you can use the boarding pass you receive online to go directly to security and then proceed to your gate. If you have bags to check, you will need to drop them off at the airport before the deadline, which is typically 40 minutes prior to departure for domestic flights and 60 minutes before for international flights. At the airport, JetBlue also offers self-service kiosks that open several hours before the flight. These kiosks allow passengers who have not checked in online to quickly complete the check-in process, print boarding passes, and tag checked luggage. For travelers who prefer personal assistance or need special help, staffed ticket counters are available. These counters usually open about three hours before departure and close 40 minutes before domestic flights and 60 minutes before international flights. At some airports, JetBlue provides curbside check-in, a service that allows passengers to check in and drop off their luggage right at the curb, saving time and avoiding long lines inside the terminal. This service is especially useful during busy travel periods or for passengers with a lot of luggage. JetBlue recommends arriving at the airport at least two hours before domestic flights and three hours before international flights to give yourself plenty of time to check in, drop off bags, pass through security, and reach your gate. For flights to and from Cuba, the airline requires passengers to arrive even earlier, sometimes four hours before departure, due to additional security and customs processes. Boarding usually starts 30 to 45 minutes before the flight and gates close 15 minutes before domestic flights and 20 minutes before international flights. Missing the gate closing time can result in being denied boarding even if you have checked in. It’s important to plan accordingly and arrive early to avoid any last-minute issues. JetBlue’s check-in system is designed to offer flexibility and convenience, allowing you to choose the method that best fits your needs, whether online, via kiosk, curbside, or at the counter. By completing check-in early and arriving on time, you can reduce stress and start your trip smoothly. Following JetBlue’s check-in guidelines and deadlines ensures that you won’t miss your flight and helps your travel experience begin without complications.
