Terrible experience on American. Four hour delay of flight 1798 DFW to CHS which returned to DFW, 2 hours after boarding!
Captain made announcement in flight that there was a maintenance problem and he was contacting tower for assistance. He came back on and said wheels would not go up,, but since still down, heading back to DFW!
Then he announced we flew by the tower to confirm that our wheels were still down and locked!! Two hours after boarding, we landed back at DFW!
Finally 4 hours later on a plane from the hangar, we departed again. In CHS more than 4 hours late!
