Yes arrival fuel might have been a cause in the past but now is unlikely.
A mate of mine used to do it all the time, so he said.
It always struck me as a bit daft that the 'Bus would have all the gismos to save fuel and descend and climb at optimum economy rates, only for the crew to go stick out the 'brakes in the descent to burn it off to prevent any aggro at the other end.
Self defeating I would say!
