Quite a luxury for NW to be able to take that much time for a Friday 5:29 p.m. flight, considering time on the ground doesn't make money.

On WN, I get frustrated when the flight is late and it doesn't look like they're doing enough to try to achieve a 20 minute or less turnaround (especially when the monitors do that cheap trick of showing the departure a mere 10 minutes after the projected late arrival time). This is a good reminder that an average turnaround is still impressive.
