ASA cannot provide enough staff to keep the sectors open
I would correct that to "ASA
choose not to provide enough staff to keep sectors open..."
Yet another example of false saving. AsA thinks they are being clever by not adequately staffing (their costs are reduced)- and who could argue that delays wouldn't be reduced by adding staff?- but the airlines pay in extra delays. No-one ever seems to reconcile the two- because
airlines cop delays and costs that have been shifted from AsA. Utterly ridiculous, and inefficient.
