What type of terminal configuration connects concourses directly to the main terminal?

The type of terminal configuration that connects concourses directly to the main terminal is referred to as a "Pier" configuration. In this arrangement, the terminal building serves as a central hub from which the concourses or boarding areas extend outward in a linear fashion, similar to the structure of a pier extending over water.

This design facilitates direct access from the main terminal to each concourse, allowing for streamlined passenger flow and ease of movement. Additionally, it often enables efficient operations, reducing the distances passengers must travel to reach their gates.

In contrast, satellite configurations involve separate terminals that may be distant from the main terminal, requiring additional transportation methods for passengers. Linear configurations typically do not emphasize the direct connection to a central terminal in a manner that resembles the pier style, and circular configurations do not create the same direct access between concourses and the main terminal. Thus, the pier configuration is distinct in its direct connectivity and operational efficiency.
