One of the most organized airports we've seen. Car rental dropoff center: buses frequent & organized lines with attendants to keep the pushing to a minimum. 2 stops, we went from the center to terminal 1 in 15 minutes. Delta has priority member line & bag drop right there. Security checkpoint has a line for 1st Class, not priority, & the line for non-first class were long, but after ids check, there are many scanners & they seemed to be moving well. Very short (& frequent) trams to D concourse, short walk even to the furthest gate (D40-43).
