CHARLESTON, W.Va. — One of Delta Airlines’ four daily round-trip flights to Atlanta from Charleston’s Yeager Airport will be upgraded to provide additional seating, more legroom and a first-class cabin option.

Starting Sept. 2, a Charleston-Atlanta flight currently being operated with a 50-seat regional jet will begin using a 76-seat Bombardier CRJ-900 regional jet with a first class cabin, “economy comfort” coach seating and on-board Wi-Fi service, Yeager officials announced Friday.

Delta’s daily Charleston-Atlanta service includes a morning flight using a 126-seat Airbus A319, the only full-size “mainline” jet now serving Yeager. With the 76-seat CRJ-900 upgrade, the airline is able to offer first-class service on two daily flights to and from Atlanta.

Atlanta is Delta’s largest hub, offering 970 daily flights to 205 destinations.

“The increase in capacity by Delta Airlines provides greater access to travelers flying to and from West Virginia,” said Ed Hill, chairman of Yeager Aiport’s governing board. “Having a first-class cabin is a great option for travelers using Yeager Airport.”
