About 85 percent of flights once again are flying in and out of Lambert–St. Louis International Airport, following tornado damage inflicted on the complex on April 22. Terminal 1, Terminal 2 and Concourse A have been fully operational since full power was restored to the airport late Saturday. American Airlines resumed service from Lambert Monday morning. Yesterday, Cape Airlines was the last carrier to resume flight. The C Concourse will remain closed for repairs. Vacant gates in the B Concourse have been opened for AirTran and Frontier airlines, and several D Concourse gates that were not being used now are occupied by American and Cape Air. No other hospitality-related damage occurred, according to St. Louis Convention and Visitors Commission president Kathleen Ratcliffe.
