In the spring of 2019, United Airlines began seasonal service to its hubs at Chicago-O’Hare, Newark, and Washington-Dulles, and American Airlines added seasonal service to its Washington-National hub to its existing service to Charlotte. Growth continued in May 2019, when Delta Air Lines resumed year round service to its hub in Atlanta, as well as adding a new seasonal route to New York-LaGuardia. All of these flights are operated by regional affiliates. One public charter airline operates limited service. It is the only airport on Hilton Head Island.
