I know for a fact that ATA Airlines takes many foreign carrier pilots, including Cathay, if they are "US certificated". It is for CABIN SEATS ONLY. I've gladly taken Cathay, EVA, Air Canada, and Jalways pilots in the past.
Not much of a scheduled service structure left there, but they do run several times a day from Chicago (MDW) to New York (LGA).
I don't know if this is a RELIABLE method for getting to work, but hopefully good info for someone in need.
