This is sort of funny. I changed my return from Pit-Ewr and took the 8:45am instead of the 5:45pm today. When I check my itineraries on CO.com it shows that I did take the earlier flight so someone (or some computer) knows I changed the flight and came back early.

I keep getting trip alerts on my cell telling me that the 5:45pm flt (which I was originally on) is delayed, leaving from another gate, etc. The recording also states that the flight is for December 8. They have the correct (orginal) flight number but the wrong date as I was always scheduled for a return on Dec. 7.

As I keep getting these it makes me happy that I made the correct decision to leave PIT early before it gets worse out there (which it sounds as if it has).
