Cignus worked with renowned Architecture and Engineering firm PGAL on a capacity assessment for United Airlines focused on the new O’Hare Global Terminal (OGT). With the OGT facility scheduled to start construction in the 2026 timeframe, United was interested in determining passenger facility requirements in the main terminal areas across the new OGT and existing terminal facilities used by United. With a focus on passenger facility requirements and using the IATA/ACRP Level of Service (LoS) approaches, Cignus worked with PGAL and United to create passenger demand scenarios, analyzed existing and anticipated building space and requirements, and determined minimum facility requirements based on standard Levels of Service. This included passenger check-in facility requirements (kiosk vs. bag-drop vs. full service), curbside check-in and frontage, premium passenger services, and ultimately security checkpoint requirements across a variety of demand scenarios.
