The weather today isn't that great either. One thing I noticed, as my Mother In Law is flying to EWR from ATL this afternoon, all the CO flights from ATL to EWR have been cancelled so far today while Delta has all theirs arriving early and then returning to ATL although they are starting to be delayed.

I wonder why there would be such a difference between carriers, my guess would be that CO is trying to minimize delays on Intl Routes and other high priority areas, but is the lesson here to stay away from CO during bad weather at EWR????
