Report: S.C. airports had 8.3% growth in Jan.

Southwest Airlines will launch weekly service between Charleston and Love Field in Dallas starting Saturday. The carrier will put that flight on its daily schedule starting in August.

Arrivals at most airports across South Carolina trended up in January.

New numbers released by the state Department of Parks, Recreation and Tourism last week show that Charleston International, the state’s largest airport, welcomed nearly 101,000 passengers to open the year. The 10.2 percent increase over January 2014 was the largest gain in the state by far.

For all of last year, the airport saw a record 3.13 million arrivals and departures. That number is expected to climb this year with the arrival of new carriers and new routes, such as a Saturday-only Dallas-Charleston flight on Southwest Airlines that starts April 11. That weekly service will go daily Aug. 9.

Other airports that serve the state also saw gains in January:

Columbia: Volume increased 7.4 percent from a year earlier to 39,300 travelers.

Myrtle Beach: Traffic was up 4.2 percent to about 31,600.

Hilton Head Island: Passenger counts at the tiny airport climbed 4.8 percent to 2,643; at nearby Savannah International, just across the state line, volume jumped almost 18 percent to about 60,300 fliers.

The growth rate for the three South Carolina airports averaged 8.3 percent for January.

The tourism department said it didn’t have updated figures for Greenville-Spartanburg International.
