United Airlines will operate out of a different wing at Charleston International Airport Thursday.
It was originally scheduled to occur Tuesday, but stormy weather prevented a crew from arriving overnight Monday.
The airline is moving to Concourse B to make way for renovations to Concourse A as part of the $189 million makeover of the 30-year-old terminal.
United will serve gates B8 and B10. Passengers exiting the new consolidated security checkpoint will go left instead of right to get to Concourse B.
United, which has been at Charleston International since May 2004, is the fourth airline to move to the new addition on Concourse B. American Airlines, US Airways and Southwest Airlines moved last week. JetBlue will move in the coming weeks, while Delta Air Lines and Silver Airways will remain on Concourse A.
The renovation at Concourse A will resemble the new construction on Concourse B with a boarding lounge that is open and bright because of expansive floor-to-ceiling windows and a 6-foot clerestory that floods the room with light.
Included in the Concourse A renovation will be the installation of five new jet bridges, seating expansion to accommodate nearly 500 people and the addition of Charleston Beer Works, an in-the-round brew pub and sports bar popular in downtown Charleston.
Work to renovate the old portion of Concourse B will occur simultaneously.
When most of the terminal redevelopment is complete later this year, the airport will have a total of 15 airline gates to serve a growing number of fliers. The Concourse A work is not expected to be completed until late January 2016.
Charleston County Aviation Authority, which owns and operates the airport, also is modernizing its baggage handling system and building new airline ticket counters.
Several parts of the airport are already complete, including the new central energy plant, new ramp space for overnight parking of aircraft, three new baggage carousels, a rental car pavilion and all new utilities.
