We departed on Sat. Dec 9th on AA 326 at 1:48pm to CLT. The process of check in and security was pretty quick. Maybe 15-20 minutes total. However, the AA CLT flight was downstairs in the gate area called “B3-B10”. Our boarding pass said gate B7, but the monitors upstairs said gate B1. There is no B1 in the terminal listed. I asked and was told the plane actually is parked on B1, but you stage to depart at the B7 gate. LOL. Go figure. Also the B gates downstairs are much warmer and congested compared to the A gates upstairs. No jetbridge on the AA CLT flight, but the MIA departure did have a jetbridge. There is an elevator to get down to the B gates.
