JetBlue also provides self-service kiosks, where customers can check-in, print boarding passes, and control seat selections on their own, making it faster and easier for technology users or light travelers.

Check-in at JetBlue's BOS terminal is efficient and traveler-friendly. Apart from self-service kiosks, JetBlue also has dedicated check-in counters for various classes of service like Mint (JetBlue premium service) and Mosaic elite members, and general economy check-in lines. There are also JetBlue crewmembers on the ground to assist passengers to the correct line or to assist in self-service stations. At times of heavy travel, the airline tends to staff more during check-in to keep the process running quickly and smoothly. For those who prefer electronic, JetBlue recommends mobile check-in through the air carrier's mobile app, which also offers real-time notifications and gate assignments.

Baggage assistance is another area where JetBlue stands out at Boston Logan. The carrier has identified areas around the check-in counters where passengers who have already checked in online or at a kiosk can easily and rapidly drop off their bags. Employees are available to weigh bags, affix tags, and address any questions related to baggage allowances or fees. JetBlue's baggage policy tends to be more liberal than that of most low-cost airlines, and the company frequently is positively reviewed for being a reasonable company in regard to checked and carry-on baggage. For oversized or specialty items like musical instruments or sporting equipment, JetBlue employees at Terminal C know their way around with these and are efficient in their handling while making sure all baggage is handled according to both airline and TSA regulations.
