Never on time!

We were scheduled to fly back at 19:25. The flight time was rescheduled 3 times after which it was moved to 13:05 the same day. At long last we only departed at 13:45. What an immense waist of time at the airport and extra costs due to arriving late and having to be caught in peak trafic. This airline does not know the meaning of being "on time". They provided no assistance with getting another flight that departed at a later time. Flight JE 339.
