Gone is the maroon carpet that covered walls near the chapel in Terminal 2.

It was a remnant of the days when Lambert-St. Louis International Airport served as a Trans World Airlines hub, giving St. Louis an abundance of direct destinations.

The new look — including new chairs, plenty of outlets, paint and equipment — is that of Southwest Airlines, which dominates airport traffic these days and is adding flights — so much so that two new gates are expected to open this week

“The concourse is full. There are no more gates,” said Rhonda Hamm-Niebruegge, the airport’s director.

The new gates are the latest symbol of the change in dominance at the airport over recent years, when Southwest has garnered roughly half the market share.

Southwest, which occupies all of Terminal 2, begins flights Tuesday to Wichita, Kan., and to Des Moines, Iowa — new nonstop destinations from Lambert — as well as year-round service to Seattle.

Gates E31 and E33 initially are expected to handle 12 flights a day between them, a number expected to grow to 16 in June when Southwest adds flights to Oakland, Calif., Cleveland and Portland, Ore.
