This was the worst airport experience I have had. We flew southwest and had to wait in line for our infant ticket that took about 45 minutes since they had only 2 agents working that line. We arrived an hour and a half before our departure as recommended. I have added a picture of what the TSA line looked on a Sunday morning at 8am. I have never seen any line this long.
We got through the line faster then expected but still running against the clock to make our flight on time. One of our trays got selected to be checked by tsa the agents took their time to change what line they were going to be checking bags at which was stressful. We could have really used that extra 10 minutes before our flight. We barely made it to the gate before we took off.
I would arrive 2 and a half hours before the departure of your flight just to be on the safe side.
