Interesting that two Scotsmen think a County with a population the same as their Country has too many ( actually two) airports .
Volume air traffic for all regional airports comes from the IT market, DSA has had only one operator supporting that market - that’s why passengers have not embraced the services of DSA in the numbers needed to make the place profitable. TUI are filling 5 airframes morning and afternoon - but that’s all that’s been on offer. Much frustration and sadness from a local, hope all involved in the airport can move on to prosper elsewhere.
