Delta Air Lines will begin offering a daily route between Charleston and Boston in June. Provided

Charleston International will land an additional daily route to Boston this summer, adding competition to the local market.

Delta Air Lines will tack on a flight to the Massachusetts capital on June 8 after launching Saturday-only service March 3, the Atlanta-based carrier announced Tuesday.

Currently, JetBlue Airways, is the only airline with a nonstop flight between the Charleston and Boston.

"I think it's a terrific recognition of the demand between the two cities," said Paul Campbell, CEO of Charleston County Aviation Authority, which oversees the state's busiest airport. "It shows Delta's confidence in the Charleston market."

He also said the competition with JetBlue will be healthy and could result in lower fares on the route.

"By committing to the flight, Delta knows it will have to compete with JetBlue," Campbell said.
