(Video above is file video.) The first-ever passenger flight from Charleston to London took off Thursday night, making it South Carolina’s first transatlantic passenger flight in history.The British Airways plane landed at Charleston International Airport around 9:15 p.m., and departed for England around 11:20 p.m.The plane is a Boeing 787 Dreamliner, but it’s not the first time the plane has been in the Palmetto State. A portion of it was made at the Boeing facility in North Charleston.The eight-hour flight will be crossing the pond twice a week until the end of October. It’ll be making the 4,000-mile journey at the same times on Thursdays and Sundays.Even before the flight, changes have already been made for British Airways at the Charleston International Airport.A new in-flight kitchen has been built, a drop-off sign outside the airport already reads the airline’s name, and some American Airlines’ ticket counters will be changing their screens to check-in those flying internationally.According to the Chris Campbell at Explore Charleston, “the flight is projected to generate an estimated economic impact of $20.2 million annually through new spending, job creation and other associated activity in tourism.”
