A lot of these places have had to change their plans so rapidly that they don't even know the answer to that question. The last few months have officially moved the needle from "warning signs, but cautious optimism" to "
global economic s**tshow." ACMI is historically a hard-hit sector in the early stages of a recession, and we should expect to see that going into 2020. I know K4 and Atlas/Southern are parking airplanes. I honestly believe that the reason you don't hear about ACMIs furloughing already is due to massive attrition to passenger carriers.
APC's airline statistics are peer-updated, and usually lag behind the actual state of affairs. The "hiring now" status is not still there out of spite. If you have other opportunities available to you, they will most likely be quicker to respond. Best case in the short term, ACMIs will hire at a trickle to cover attrition. Worst case, one or several ACMI carriers will fail, and over a thousand more pilots will be competing with you for all the other jobs you need to be looking at right now.
