From what I know and it is alot. There are guys coming over to SKW from Xpress Jet, Don't know of 1 soul that has gone from SKW to Epress Jet though.
Just an observation???
When ExpressJet began recalling after 9/11, many of the people who took the "props for jobs" deal at SkyWest went back to ExpressJet. They had a choice to stay, but many went back.
