ORLANDO, FL

Our trip to Orlando was nice after we finally got there. Delta put us on a plane not in the seats we had purchased but the back row against the tail or the plane. My huband has a bad knee from the military and was very unconfortable. We specified a certain seat as we knew he would be able to move about in the seat and not have such pain in his knee. Then after we got stuck in those seats we receive an anouncment from the pilot that the plane has not been warmed up and the has to rebout all the systems. This took 30 minutes and not we were late leaving. Then he came back on and told us there was somehting wrong with one of the engines of the plane. He said they needed to have the maintance person come and irx the problem. We were now 45 minutes leate in leaving. Then he came on and said it would take another 330 minutes or so to do paperwork about the problem and we would be leaving in about 30 minutes. We finally left and found we were 1 and 1/2 hours late and that we would be missing our connecting flight in Atlanta. We did miss it and had to locate another flight to make the connection. We got to Orlando 2 hours later than we were supose to and missed our friends coming in . The went Continental and arrived on time. We took Delts and had all sorts of problme. On the flightr home they once did another error. They had taken away out seats from Orland to Atlanta and was going to give us separte seats away from each other. They fixes it after I told them I was going to report them. When we got to Atlanta Delta flight back to Sacramento put us in the back of the plane in those seats my husband could not move in. That flight was 5 hours so getting up to get out he could not stand up. The parks and our hotel was really night and so way the staff but the air flight was terrable. Both ways. I feel Delta needs to offer some sort of apoligy Delta staff told us it was your falt that we did not get the seats we chose as you did not send in the reservatiation in in time. Why?
