United Airlines will consolidate its operations in concourse C at Cleveland Hopkins International airport in June, as it dismantles its hub at the airport.
The Chicago-based carrier will operate all of its flights out of concourse C and end operations in 16-gate concourse D, which served regional flights, from 5 June, it says.
United uses 24 gates in concourse C but was not immediately available to comment on whether it planned to continue to use all of the gates.
The airline plans to operate about 70 peak day flights from Cleveland from June, which would require about nine gates assuming a maximum of eight turns per gate based on US National Transportation Research Board (TRB) recommendations.
United will continue to operate a United Club at the airport, it says.
Continental Airlines built concourse D for regional flights in 1999. Continental merged with United in 2010.
