The recovery of operations from tornado damage on April 22 continues to accelerate at Lambert-St. Louis International Airport, which expects to airlines to operate their full flight schedules on Tuesday.

On Monday, airlines flew nearly 90 percent of scheduled flights, according to an airport news release.

The C Concourse, which was heavily damaged by the tornado Friday night, will remain closed indefinitely.

Frontier and AirTran are now operating out of the B Concourse. American and Cape Air are operating out of the D Concourse. The Airport has brought in some new food services to those concourses and will continue to expand concessions through the week.

In other developments, Lambert extended its post-storm policy to waive parking fees for customers who exit any of the terminal garages and the other Airport-owned Super Park parking lots — A, B, C and D — by Monday night. Parking charges will resume Tuesday at 6 a.m. Only customers with vehicles damaged by the storm will have their parking charges waived after Monday, the release stated.

Super Park lots B and D remain closed except for returning passengers due to the extensive damage to vehicles during the storm. Those lots will re-open as soon as vehicle and storm debris are cleared and parking systems are brought back online.

Customers can park at Super Park Lot C for same economy price as Lot D, which is $7 after all lots reopen.
