I've got to agree that MCO is one of the worst I've ever faced. I was just through there last week and, midday, the lines were taking 45+ minutes to pass through the ID checker and WTMD's. And MCO no longer has an "elite"/First Class speed line, at least not for the DL gates.
Other airports rival MCO on occasion.....FLL, BWI, SEA and PVD immediately jump to mind....but I agree that MCO takes the cake day in and day out.
