Frick. I'm booked on a flight around this time as well. Typical Delta - I received no notification of the change. With that said, Delta was super helpful and rebooked my Thurs-Sun itinerary into a convenient same-day turnabout. They seem to think I might have trouble making that "connection" though... what's the I-I MCT in CZM?
What's the point of running a once a week schedule? That's infrequent enough to be patently useless...
