| There are so many problems with every aspect of this airport. I'm going to list problems with some no-cost or low-cost solutions. 1) Concourses are narrow, so pedestrian traffic is a mess. People are constantly bumping, almost bumping, crossing in front of, and getting behind slow people. Last night, a member of the cleaning crew had parked a rolling garbage bin in the middle of the concourse (E) and was off to the side having a casual conversation with a vendor. This caused many pedestrian issues, in an already stressful environment. Solution: train cleaning crews about traffic in the concourses and how to treat customers better and NOT block their paths. 2) Continual gate change for arrivals, and - what seems like - confusion for the airplane waiting to pull into the appropriate gate. I don't know how much larger airports are so organized, but CLT needs to have systems in place for parking planes quickly at their gates to get people to their connecting flights on time. Last night in Concourse E Gate 17 (6/13/2019), 5 breathless passengers showed up to catch the last flight to Columbia SC that day. The unconcerned gate employee told them the doors were closed, and there was nothing he could do. Their incoming flight had been blocked from their gate for a time, making them late to the Columbia flight and that flight pulled away without them. super simple, cheap solution: have a gate ready for each arriving plane. If a plane has passengers for connections, communicate with their connecting plane's crew to please wait 3-5 minutes for the passengers to arrive. 3) Some of the slide-walks weren't working, and you need that extra boost in speed to reach long distances between connections (see above). Solutions: maintain existing equipment and keep it running. 4) Lots of trash, lots of people working who seemed to not want to be there, and boarding queues crowding the already narrow corridors - there needs to be some management improvement at this airport. All of this makes me feel less safe flying.
