Joe Brancatelli is updating his subscribers every few hours -- it appears that there are more-than-normal delays systemwide today and he mentioned that ontyime performance is 65% at best.
I fly from MSN and NW is the dominant airline here -- there are currently 2 flights on the board:
1745 MSN-DTW scheduled 1:35PM, now 4:10PM (Delayed)
4740 MSN-DCA scheduled 2:30PM, now 3:24 PM (Delayed awaiting aircraft)
This is Saturday. The real test will be tomorrow and Monday. But I've been looking at MSN departures all day and most NWA flights left late.
