Skywest and Hazelton/Kendall (now REX), which were all on separate AOCs from mainline AN's AOC, was sold off and restarted when AN collapsed.
VA regional is using the Skywest AOC. So it'll likely be the same case if VA was to file voluntary administration shortly, Skywest (VA Regional) would be restarted through the existing VARA AOC as soon as it's possible after administration.
