The Charleston County Aviation Authority voted Thursday to begin the process of selling 320 acres to Boeing Co. The price has not been set.
The authority voted to give Boeing first rights of refusal on nearly 500 more acres, as well as an option to buy another 265 acres.
Boeing has not announced any plans for the land. But Boeing South Carolina chief counsel Mark Fava says the company doesn't "bank" land it doesn't plan to use.
Fava says the company brought up the idea of buying more land from the aviation authority months ago.
Charleston Mayor Joe Riley says the purchase plans are good news for the area.
Boeing makes 787-passenger jets in North Charleston.
