This is a job well done by AS. Swapping air frames. causing a delay of <1 hour on departure and making up 1/2 of that enroute, is good work. Too bad ground congestion got in the way, but there is a limit to how many aircraft can move at any minute. Not only does AS not control that, but the reality is that either there are some controls or the whole place becomes a parking lot and nothing moves.

This is much ado about less than nothing.
