Inside Cleveland Hopkins International Airport

Cleveland Hopkins consists of one two-level passenger terminal, which was completed in 1978, and renovated in 2016. This replaced the original jet-age terminal dedicated in April 1956. There are four concourses, three of which are currently in use:

Concourse A (gates A1–A3, A5-A12, A14) houses Allegiant Air, Frontier, Spirit, charters, and all international arrivals. Delta Air Lines also uses it for overflow parking and sports charters. It also houses the airport's Federal Inspection Services (FIS) customs and border protection facility. Originally known as "North Concourse", it was opened in 1957 and rebuilt in 1978-79.
Concourse B (gates B1–B11) houses Delta and Southwest. It was built in 1954 as the first extension pier to the airport, and was rebuilt and expanded from 1982 until January 1983.
Concourse C (gates C2–C11, C14, and C16–C29) houses Air Canada Express, American, JetBlue and all United services, except for international arrivals which are handled in Concourse A. Originally known as "South Concourse", it opened in 1969 and was renovated in 1992.
Concourse D (gates D2–D12, D14, D17, D21, D25, and D28) has been vacant since June 5, 2014, when United closed its gates and consolidated all operations to Concourse C.[22] Built in 1999, it is a separate terminal connected to Concourse C by an underground walkway. Although capable of handling larger jets such as the Boeing 737,[ it exclusively handled smaller regional aircraft during its operation. Concourse D contains 12 jet bridge gates and 24 ramp loading positions.[
