Coming from CO, the system automatically recognizing me by my caller ID phone number is a big upgrade.

Too bad it's completely offset by its inability to:

1) recognize "existing reservations". at. all.

2) recognize "yes"

3) recognize anything, really

This must be the CO system because that system had trouble recognizing anything also, even spelled out OnePass numbers, I always had to type it in on the keypad. Good thing "1" = "Yes", so I can fix #2. Delta has pretty good IVR voice recognition.
