About a month after AirTran moves to take up some of the current Southwest counters, Delta Airlines will move to AirTran's former space. The current Delta counter near Concourse B will be converted to a new checkpoint — the airport's largest — as part of the $100 million project.

Air Tran will move to A and B and Delta will move to D with Cape Air, UA/CO, JetBlue, and US.

A/B will be only Southwest and Air Tran, while C will only by AA.
