St. Louis-Lambert Outlines Terminal Expansions Following the Addition of New Flights

While many terminals don’t get a second chance once they close, Lambert-St. Louis International Airport is doing the opposite. The former TWA hub has seen great declines in air service compared to its 2001 performance, however the airport is seeing a slow rise in traffic thanks to Southwest Airlines. As a result, Lambert is starting to revive the old Terminal 1 – Concourse D.

Concourse D’s far eastern end has been renamed part of Terminal 2 with changes to gates D34, D36, D38, and D40 to E34, E36, E38, and E40. This change will leave the closed Concourse D with only thirteen gates. Concourse D hasn’t seen service since 2011 when Cape Air and American Airlines needed a temporary home after a tornado had damaged Concourse C.

However, the gates that are being remodeled haven’t seen service since American Airlines downsized their St. Louis hub in 2006. Despite St. Louis renovating four gates, much of the airport remains behind walls with Concourse D shielding 13 gates (D0-D32), Concourse C’s far end (gates C29-C38), and all of Concourse B.

The new gates are only going to be prepared for service but not open to the public yet. Current work at the concourse involves changing out the signs and replacing the carpeted floors with tile to match that of Terminal 2 as well as giving the walls a new coat of paint.

The gates will not be fully prepared either, so Southwest will be in charge of adding their signage and well-known boarding towers should the carrier choose to operate out of the space.

Southwest has seen rapid growth in St. Louis over the recent years. The carrier took hold of 12 slots at Terminal 2 gates E31-E33 when the gates aren’t in use for international arrivals of Xtra Airways and Frontier Airlines.

Southwest, who has taken over number one carrier in St. Louis after American dismantled their hub, has topped 100 daily flights from St. Louis in 2016 and added new routes to Little Rock, Des Moines, Oakland, Cleveland, Pittsburgh, and Wichita last year.

Future destinations for Southwest in St. Louis include Charleston and Pensacola which both start in June 2017. While the first four gates should help expansion, St. Louis will have to make more strategic decisions in the future with some of Concourse D lacking jetbridges and Southwest expanding farther away from their check-in counter in Terminal 2.

    Although Ian McMurtry was never originally an avgeek, he did enjoy watching US Airways aircraft across western Pennsylvania in the early 2000s. He lived along the Pennsylvania Railroad and took a liking to trains but a change of scenery in the mid-2000s saw him shift more of an interest into aviation. He would eventually express this passion by taking flying lessons in mid-Missouri and joining AirlineGeeks in 2013. Now living in Wichita, Kansas, Ian is in college majoring in aerospace engineering and minoring in business administration at Wichita State University.
