The number of people flying in and out of Charleston International climbed to a new record during the first six months of the year.
In June, 446,314 ticket holders traveled through the airport, up nearly 20 percent over the same month last year, according to the Charleston County Aviation Authority.
That pushed the number of passengers for the first half of the year to more than 2.1 million, up 10.4 percent over the same period last year.
"We knocked it out of the park in June," said airport CEO Paul Campbell.
Several airlines have added new routes while others such as Frontier and Allegiant launched service this year in and out of the Lowcountry.
On Aug. 15, Denver-based Frontier will offer nonstop flights twice a week to Minneapolis-St. Paul, a new destination for uninterrupted service from Charleston. Flights will be on Wednesday and Saturday through Nov. 14.
The passenger totals for the first half of the year could push Charleston International to a new record this year.
"We are on track to top 4 million passengers in 2018," Campbell said. "That will be a major milestone for CHS."
He added that the total could reach as high as 4.4 million.
Last year, 3.98 million travelers used the North Charleston airport, the busiest in South Carolina.
