Delta Air Lines and the City of Atlanta executed Amendment No. 4 to their Airport Use and Lease Agreement to expand the Existing B Sky Club at Concourse B by approximately 23,000 square feet. The Atlanta City Council waived competing procurement requirements and authorized up to $88,200,000 in City reimbursement for the shell project, including core and shell construction, building systems, and related improvements. Delta will finance all interior tenant finishes without City reimbursement and will lease the expanded premises under the terms of the existing AULA, with adjusted rental payments reflecting the additional space. All contracted work will be charged to and paid from designated Aviation Encumbrance Program accounts. The Interim Chief Procurement Officer and City Attorney will prepare the amendment, which becomes binding only upon execution, attestation, form approval, and delivery to Delta.
