There's more.
Got to CVG with time to have dinner at Gold Star. After I finished my 4 way, I looked at the departture screen to find my CVG-BHM cancelled. CRC closed, so I called SMS. I was told I was "protected" on a 9:15 flight tomorrow morning.

I asked about a CVG-ATL flight that was delayed 2 hours and was told it was in the hands of the gate agent so I headed there.
Nice Comair lady put me on the flight, assured me it was 15 minutes out and would turnaround quickly. Boarded and sat down. Didn't realize I was in F until the FA asked me if I wanted a drink.
Hurray Delta. Boo Avis.
Called Avis to move pickup location from BHM to ATL. Was told no more 1 way rentals available. ATL was a madhouse at 11:30 last night. Lots of late flights and cancellations and no 1-ways from any agency.
Booked a car and returned this morning. Bottom line: slept in my own bed last night. Initiative? Mine.
