Somehow got a voucher out of BNA in August on a Sunday evening. Was originally scheduled to take the 7p late flight out of BNA to ATL and connecting to the 11 p.m. to CLT. Earlier in the day, I SDC'd my way onto the 5p BNA/ATL despite being a ridiculous fare (X? T?). I got to BNA and found out that the late flight was delayed, which resulted in Delta overbooking the 5p.
Got a $500 voucher, took the 7p (delayed until 8p), got in to ATL at 10, made my original connection to CLT with plenty of time to spare and was UG'd the whole way.
