We returned (day 2 in Iraq) and were on a 12:45 SW flight. ALL baggage was being searched.
We were at the airport and in line by 9:45 and decided to inquire if there was still space on the 11:30 flight. Well, there was but for $40 and 1-1/2 hours difference, we decided to just keep our original flight, since we probably would have had a "C" boarding pass at that point!
