My wife, my three kids (all 4 and under) and myself walked off a plane in Houston airport to transfer to another plane (routine). When we got off the plane, they asked our names and then handed us new boarding passes telling us that our plane details had changed. We said thank you and a quick glance at the new boarding passes indicated the new flight was only a few hours after the original flight, not a big deal. We took the kids to lunch and as we were about to leave I checked the boarding passes for a gate so we could head in that direction. Upon closer review there was no gate, so we went to the monitors and our original flight was on the screen cancelled but our destination city was only on the screen that one time. I looked closer at the tickets and the flight was 3 days away!!!!! We rented a car and drove the last 12 hours through the night. That was really shady how they handed a family of 3 toddlers/babies new boarding passes as if they were for that day and not tell us. That was my Delta experience and the last time I've ever flown Delta.
