If you’re flying through Saint Louis, this week, be sure to check in with your airline. Lambert Airport says about sixty percent of the scheduled flights took off, there, yesterday. They don’t expect to be fully operational until mid-week. American Airlines does plan to resume flights, today, through a concourse that has been closed several years. AirTran flights are operating out of other gates. Concourse C, where they were based suffered extensive damage from a tornado and will not reopen for several months.
