Lambert-St. Louis International Airport reports that approximately 70 percent of flight operations resumed less than 48 hours after an EF-4 Tornado system damaged the airport complex on April 22.

The first arrivals into Lambert came in late Saturday to make way for both departures and arrivals on Easter Sunday. Lambert’s Terminal 1, Terminal 2 and Concourse A are fully operational after full power was restored to the airport late Saturday, according to a news release.

Eleven airlines had scheduled flights on Sunday. American Airlines will resume service from Lambert on Monday morning. Cape Airlines will be the last St. Louis carrier to resume flights which is scheduled to begin on Tuesday.

Because of the damage to the C Concourse, it will remain closed. Lambert has worked with the carriers in that concourse to move their operations. Lambert has re-opened once vacant gates in the B Concourse for AirTran (B12) and Frontier (B10). The B Concourse checkpoint is also open to serve those airlines. Lambert has also re-opened several D Concourse gates which were not being used for American (D2, D4, D6, D16 and D20) and Cape Air (D 8, D10).

“We give tremendous credit to Ameren for restoring service to Lambert so that the airport could open just 24 hours after the devastating tornado,” Director Rhonda Hamm-Niebruegge stated in the release. “Thanks also has to go to the numerous crews and workers who have worked with the airport to clean up and make emergency repairs to get where we are today.”

Hamm-Niebruegge said Lambert’s airlines probably will reach 85 percent capacity on Monday. For April, Lambert has been operating 256 daily departures per day.

Travelers should still contact their airlines for the latest flight information.
