My wife and I arrived for our departure flight at Denver [International Airport] on a Sunday about two and a half hours early; plenty of time for screening, so we thought.
We were floored by the length of the security lines for both South and North screening. They stretched out of the standard bullpen and snaked around the terminal. I was sure we would not have enough time to get through security and make our flight.
I know you get a lot of complaints, but we were blown away by the speed of the process and the patience of the TSA staff. We were at our gate with plenty of time to board.
