AA 457 PHL-CLT delayed today 1 hour, captain actually said it was due to waiting on an expensive cargo shipment of wine. We got to the gate at 6:00, I sprinted from B12 at CLT and got to E7 at 6:08, door closed as expected and plane still sitting there, was able to reroute to STL and will have to rent a car and drive home, hopefully anyway.
