Whether it's correct or not, the Northern Echo article does explicitly state that the Sunday flight stops:
The last flight to Southampton will take off on Friday, September 2. Eastern’s four flights a day from DTV to Aberdeen, used mainly by workers in the oil and gas industry, will continue.
Falling passenger numbers were behind the decision to suspend the twice-daily Southampton service, which started in November 2009.
The Sunday flight will also cease.
A spokesman for Eastern Airways said frequency adjustments, timing changes and lower fares had failed to stimulate more demand, adding: “At a time when the economic climate is still very challenging and fuel costs continue to rise sharply, we’ve taken a tough decision to withdraw and concentrate on our core routes, as this service is not commercially viable.”
