Not to diminish the awful experience by the OP, I flew in and out of DFW on Saturday and Sunday. It was a mess. The Saturday afternoon weather delayed flights and I was lucky to get out even 2 hours late.
My return flight to DFW was delayed as the inbound aircraft was caught in that mess.
Arrived back at DFW Sunday, where it seemed more than half of the pax on my flight had missed their connections. When we landed, the FA started reading off a long list of every connecting flight destination where pax were headed, which had already been rebooked by AA and the gate numbers, and which pax had to go and deal with rebooking. It was both impressive and nuts.
