I was talking to a CK last week based in CLT. They were outbound for vacation May 3, ultimately to IST on AA/BA in J. Plane cancelled, all they could get was Y to IST TATL to get there late. Kinda sucks when a CK can't even get rebooked in the paid class on AA. Fortunately we were on UA and got in to EWR on the return (same cruise as the CK), but T storms cancelled us there and we flew the next day in Y, so same story, different carrier, different airport. DFW does this a lot.
