The self-service kiosks at the Spirit Airlines BOS Terminal serve primarily for registration, allowing visitors to effortlessly tag their luggage and generate boarding tickets. Spirit employees are available to help with any problems or unique requirements if you need extra support. After checking in, travelers head to the security checkpoint, where Spirit employees and TSA officers make sure the screening goes well. The entire check-in and security process is well-organized and effective because lines are usually manageable and passengers with TSA PreCheck enjoy quicker treatment.
