Missouri’s busiest airport is headed for its least-busy year since 1983. And some studies indicate it might be two decades before Lambert-St. Louis Airport gets back to where it was before the 2001 terrorist attacks. The St. Louis Post-Dispatch says the gloomy present, and the dim outlook are not stopping a one-billion dollar runway expansion program, though. Airpoirt Director Leonard Griggs says the airport has added about 50 flights a day since American Airlines cut its service in half.
