Facilities. United has major terminal facility leases at SFO, IAD, ORD, LAX, DEN, EWR, IAH and GUM. United leases gates, hangar sites, terminal buildings and other airport facilities in the municipalities it serves with lease expiration dates ranging from 2026 through 2057. Substantially all of these facilities are leased on a net-rental basis, resulting in the Company having financial responsibility for maintenance, insurance and other facility-related expenses and services.
United also maintains administrative, catering, cargo, training, maintenance and other facilities to support its operations in the cities it serves. United's leases for its principal executive office and operations center in downtown Chicago and administrative offices in downtown Houston expire from 2029 through 2033.
