The New York-based airline begins service out of Charleston Thursday with three daily flights, two to John F. Kennedy International and one to Boston’s Logan International.

“What a credit to Charleston for advance sales,” said Helen Hill, executive director of the Charleston Area Convention and Visitors Bureau, which lobbied for nearly three years to bring the airline to the Lowcountry.

JetBlue, which hoisted its bright blue sign at its airport kiosk Wednesday, brings 15 employees, with seven of them hired locally, airline station manager Chris Plunkett told the Charleston County Aviation Authority at its monthly meeting Thursday.

“We are excited to be here and serve this great community,” he said.

JetBlue announced in September that it would start service at the end of February out of Charleston.

A reception, including a water cannon over the first flight, is planned for Thursday when the first flight from New York touches down in Charleston. It is scheduled to land shortly before 10 a.m.

The appraisals are due March 20.
