AirTran have moved their Gates from Concourse 2 to Concourse 4, using the 90s Gates wing of this concourse. The DL ticket counter staff told me that since this has happened the outbound baggage handling system has gotten overwhelmed with bags and the DL security check point as well. They suggested that I use the SW checkpoint, from which you can also get to Airside 4 where DL and AirTran are, which I did as the DL checkpoint is now very busy, especially in the afternoon when Int'l flights are leaving Airside 4. Airside 4 is now a zoo at certain times of the day with the addition of AirTran to it.
From what I saw in the way of volume of bags at the TSA checked baggage screening points, IMHO you stand a good chance of your checked bags not getting on your flight unless you check in real early. Better still do not check bags at Orlando unless you have to.
Finally the TSA have changed again the way they handle Int'l arriving passengers on Airside 4 so that they do not have go through arriving TSA security on Airside 4. They seem to control both people movers at certain times of the day when Int'l Flights are arriving and are herding passengers here and there and of course, barking at them. Makes it a real pain at times to use the people movers.
Thought that this would be useful information for FTs.
