An estimated $23.4-million upgrade of the inbound bag handling set-up is in the works for St. Louis Lambert International Airport's Terminal 2.

The city Airport Commission on Wednesday will consider a proposed 10,500-square-foot expansion of the terminal's baggage claim area.

Tentative plans call for the two existing baggage carousels to be replaced by new ones and a third carousel added.

Upgraded conveyor belts and other equipment also would be involved, as would construction of a new transfer facility where bags are taken from arriving flights.

The terminal's primary tenant, Southwest Airlines, would cover about $16.3 million of the estimated cost, with the airport paying for the rest, some of it through existing passenger charges.

Approval also is needed from city aldermen and the city Board of Estimate and Apportionment.

Meanwhile, Lambert and Southwest have been discussing the possibility of moving Southwest's curbside baggage check-in area at Terminal 2 from the north end to the south end of the vehicle drive for departing passengers. 

However, Lambert spokesman Jeff Lea said no decision has been made on whether to make such a move.
