The Lehigh Northampton Airport Authority said a plan to sell a chunk of land will likely be a long process.

Earlier this year, a New York-based company, called the Rockefeller Group, said it wanted to buy 753 acres of farmland owned by the authority.

Officials said the plan is moving forward, but because the land spans several townships, there are going to be different zoning issues that will take time to resolve.

The authority said the money generated from the sale of the land would go toward capital improvements and to pay the balance of a $28 million lawsuit.
