Chick-fil-A is touching down for seconds at Denver International Airport. A second location of the Georgia-based fast-food chain is planned for Concourse A, according to a contract going before the Denver City Council. Skyport Holdings LLC, a concessionaire that already has a presence at the airport, plans to operate the restaurant in 1,700 square feet at the “core” of the concourse, where passengers emerge after getting off the shuttle from the main terminal. The contract still needs to be approved.
