There wasn't a perceivable reduction in flights and pax numbers to and from Sumburgh & Scatsta out of Aberdeen in 2016, in fact they seemed to get busier and more frequent. However, flights into Aberdeen on the feeder routes did quieten down considerably.
One thing that didn't help of course was that pax and crews were continually messed around to an unbelievable degree, so much so that both groups abandoned the airline in droves.
