worst is with American Airlines in USA. flight delay and malfuction airplanes kept us on the ground for six hours while others flights to the same destination took off. After we get there, the connection could not be made until the next day. Then there was the delay again, must be the same plane? The trip was 500 miles and it took two days to get there. It was over the weekend and started on Thursday. When i got there Saturday I was on the ground for two hours before my return flight home....Neveer fly AA in my book again.
