Geesh Delta. 6 hours late leaving ATL. Waiting on a flight crew to land to fly us to LA. They are on the ground, boarded, flight crew arrives, times out for the day, can't fly, unboard, wait, New crew coming, board, they arrive, have to check everything, computer problems, manual tool call all persons on plane, unruly passenger, police remove with federal charges, now so late waiting on connecting flights to land, finally we go, sudden rapid descent, pilot on, no room for us at LAX, diverting to Vegas, land, medical taken off of plane, sitting on plane at gate, Delta telling us nothing so far. My Tuesday is toast.
