I just suggest to people to avoid a short connection in CLT now. AA is able to command very high yields from CLT so they've built it up, but the taxiways can't handle it, so one hiccup causes us to arrive a few minutes late. A 777 had pushed off our gate, and they naturally tend to take longer to get out. Then the gate area has to be reconfigured for a narrowbody, meaning carts and equipment has to be moved. We finally block in 15 minutes late. CPB is a mess, and then I get out to see the TSA line is all way down the main ticketing concourse. ORD operates better than CLT does now.
