What does the term "airside" refer to in airport operations?

The term "airside" specifically refers to the segments of the airport that can only be accessed after passengers have cleared security. This is the zone where you find departure gates, lounges, and other facilities directly related to the boarding process for flights. Being on the airside means that an individual is in a secure area where only authorized personnel, crew, and travelers with a valid boarding pass are allowed to be. This separation is critical for maintaining security and safety within the airport, ensuring that only vetted individuals can access the areas where aircraft are docked and boarded.

The distinction of airside from other areas, such as those accessible without security clearance, plays a crucial role in airport operations, as it helps manage the flow of passengers and maintain the integrity of security protocols.
