The region's petroleum and tourism industries have helped foster growth at the airport, which has nonstop flights to an array of destinations in North and Central America, Europe, and Asia. Calgary serves as the headquarters and primary hub for WestJet.

The second level of the terminal serves as the departure level and includes airport check-in, security and access to departure gates. The basement level of the airport contains utilities and tenant storage while the mezzanine level contains a food court, airline offices and the airport authority offices. The Domestic Terminal has four concourses: Concourses A1, A2, B, and C. All A, B and C gates are shared between domestic airlines such as Air Canada and Westjet and their subsidiaries.

Arrivals meet and greet areas, Canada Customs and relevant infrastructure on the ground level with departure check-in, security, US customs and the international departures concourse being located on the second floor.

The International Terminal includes gates 70 through 97 shared across two concourses: Concourse D for all flights to and from foreign countries except the US as well as domestic flights; and Concourse E for flights to and from the United States. For the International Terminal, passengers travelling to the United States clear customs and immigration before departure at the preclearance facility.
