JetBlue allows passengers to check in for their flights starting 24 hours before the scheduled departure time. Online and mobile check-in opens exactly 24 hours prior and closes 40 minutes before domestic flights and 60 minutes before international flights. To check in online, passengers visit the JetBlue website or use the JetBlue mobile app, where they enter their confirmation code or TrueBlue account information, select or change seats, add any baggage if needed, and obtain their boarding pass. The boarding pass can be saved on a mobile device, printed at home, or emailed. This method is recommended for travelers without checked luggage or those wanting to save time at the airport.

At the airport, JetBlue offers several options. Self-service kiosks are available in most terminals and allow check-in starting 6 hours before departure for flights with checked baggage, and 24 hours before for flights without checked bags. Passengers can print their boarding passes and baggage tags at kiosks, then proceed to bag-drop counters to check their luggage. The kiosk option speeds up the process and reduces time spent in lines. For those who prefer personal assistance or have special requirements, counter check-in desks open 3 hours before departure and close 40 minutes prior for domestic flights and 60 minutes for international flights. At the counter, agents assist with check-in, seat selection, baggage drop, and travel documentation.

JetBlue also provides curbside check-in at many airports, primarily for passengers with checked luggage. This service is available starting 6 hours before departure and closes 40 minutes before the flight for those without checked bags. Curbside check-in allows travelers to hand their bags directly to airline staff outside the terminal, which is especially useful for passengers with heavy or multiple bags or those needing extra help.

Regardless of check-in method, passengers should arrive at the boarding gate well before the closing time, which is typically 15 minutes before departure. Gates close promptly, and missing this deadline may result in denied boarding. Passengers with checked baggage are advised to complete the check-in and bag-drop process early enough to allow time for security screening and reaching their gate.

It is important to note that for international flights, passengers must ensure all travel documents such as passports, visas, and customs forms are ready during check-in. Failure to present the proper documentation may prevent boarding or cause delays.

JetBlue encourages travelers to check in online or via the app to avoid airport lines and to pay for checked baggage fees in advance if applicable. For families traveling with infants or children requiring special assistance, check-in counters are recommended to ensure proper handling and any necessary documentation.

Passengers should be aware that check-in times and procedures might vary slightly depending on the airport or destination. Therefore, it is advisable to review JetBlue’s official guidelines before traveling. Overall, JetBlue’s multiple check-in options—online, mobile, kiosk, curbside, and counter—provide flexibility and convenience to suit different passenger needs. Starting check-in 24 hours before departure and adhering to the specified cut-off times guarantees a smoother airport experience and helps avoid last-minute stress.
