Non-reving (employee) on a Delta 767 from Jacksonville to Atlanta. We pushed back from the gate and immediately pulled back in with a mechanical. Because Northwest had a flight at the next gate leaving a few minutes later, all the paying passengers were moved over to that NWA flight. Because one of the 20 or so non-rev employees was on her way to her father's funeral, rather than ferry the aircraft to Atlanta the captain requested flight control run it still as an active flight so they could carry us. So we get the airplane fixed and 20 of us have a 200 seat aircraft to ourselves. First, on taxi out the flight attendants told us if we wanted anything in the way of drinks and snacks on the flight, get up and get it from the galley ourselves. Then we got out to the runway at the hold short line and the co-pilot comes over the PA and said (I kid you not), "OK, we're going to take off now so everybody sit down and keep your feet off the seats!" After takeoff and we got above 10,000 ft the captain came over the PA telling us, "Anybody that wants to see what we do up here, come on up." So I got to ride 90% of the flight in the jump seat all the way to the gate in Atlanta. Landing was interesting in that the aircraft was so light, it wanted to stay flying and they had to actually fly it to the ground.
