That's interesting... I was on that flight on Friday afternoon (and on the MKE-FNT on Monday afternoon that turns around and becomes 1169.). It's an EMB-135 operated by Chautauqua. I recall that the cards were not Midwest specific (like the OO flight from PHL-MKE) but I can't imagine what was wrong.

Granted it's not the same plane... But yeah, what a weird delay.
