I'd say about 5-10% of the wokforce is furloughed (or out of work due to cessation of operations), so probably about 4,000-6000 out of the roughly 80,000 airline pilots in the US (if you include the impeding furloughs that have been announced at places like UAL for the fall). American alone has nearly 2,000 furloughed pilots according to apc, although i can't say how many of those are flying at eagle or elsewhere. You can go to apc and add up the numbers if you really want an exact figure.
