MSP: we have one. I got in 'this line' on Wednesday pm around 1:30. It was so long I questioned whether I was in the correct line. We were all pretty disgruntled as it took over 25 minutes to get through security. Petty, I know, but uff-da!!!
MDW: don't get in the expert line. I keep doing this but when you round the corner, it comes to a dead stop. People don't seem to understand that you need to take off your belt, jacket, put the laptop in a separate bin, etc. I had somebody comment in that line to me that "you really know what you are doing." "This is the expert lane," I replied. Crickets on the response.
