The ticketing area is generally less secure than the area beyond the security checkpoint. The area beyond the security checkpoint involves more stringent security measures, including TSA screening for passengers and carry-on baggage to intercept prohibited items. Only ticketed passengers are permitted beyond the checkpoints, and this area is controlled with thorough inspections such as metal detectors and X-ray machines. In contrast, the ticketing area is more accessible and does not require passing through these security screenings yet.
The security checkpoint marks the transition from a publicly accessible zone (like ticketing) to a secure area where access is strongly regulated to ensure aviation safety, making the post-checkpoint area more secure overall.
