GLA management is caught between the 1,500 hour rule, the economics of their service model and the number of customers in their geographical area. In addition, they are now stuck with a fleet of aging twin turboprops that made sense at one time, but now are higher-cost to operate (fuel, flight crews and maintenance on older airframes).
They can't do anything about the cost of fuel. They've tried several things to staff their cockpits, but despite raising wages, in today's pilot competition they (like virtually every regional) can't attract and retain enough flight crew. They don't have the money, or investors, to replace their Beeches and Brasilias with newer planes that take less maintenance, or to right-size the fleet to Pilatuses and Cessnas to match their route structure and number of customers. I don't see EAS coming to their rescue with huge increases in subsidy payments (more than half GLA's cash flow comes from EAS flying).
What once worked, now doesn't. Too bad.
