I did the opposite, but just as frustrating. I figured I'd gamble with the weather waiver, I couldn't leave any earlier and I didn't really want to delay my trip into BNA. Wrong choice!
Flying JFK-BNA today (6p departure), woke up at 8am to a notification that it had been cancelled. Rebooking tool was showing me some fantastic options, 3 flights starting at 10am that would take me to a 5 hour layover in GRR before landing me at BNA.
Called into the Plat line and got rebooked on LGA-DTW-BNA arriving just a couple hours later than originally planned, but who knows if that'll happen given the weather situation right now.
This has been all too common here in the NYC area (and the larger NE) this year. A bit of bad weather throws everything into disarray, and it can take a looong time for ops to get back to normal after something like this happens
