Narrative:

At FL310, approximately 30 mins after takeoff, I heard a loud bang and could hear a very loud rush of air through the cabin. I could also feel the floor under my feet vibrate. I immediately reported to the cockpit. After checking the cockpit instruments, the aircraft began descending to lower altitude, oxygen masks never dropped, the flight returned to dfw. Aircraft had history of loss of cabin pressure. Callback conversation with reporter revealed the following information: the reporter stated that in first class, the passenger felt rumbling underneath their feet and everyone's ears started having problems. She went up to the cockpit and they weren't aware that anything had happened, and just as she finished telling them, the cockpit instruments started going wild. The pilots immediately donned masks and started an immediate descent. They told the cabin crew that they didn't have to don walk-around oxygen bottles and that there was no need to prepare the passenger for an evacuate/evacuation. They could continue serving, but not to have any carts in the aisle. The captain said that the logbook showed that the plane's last flight had been a week ago, and that it had climbed to 10000 ft and had another decompression. The mechanics had replaced all sorts of seals and ground tested it and sent it out again on their trip. She said that there was excellent cabin/cockpit communication and coordination. The plane was taken OTS again.
