Upgrade time for F/Es? They probably hire 'Professional" F/Es, guys that have lots of heavy-jet FE time, ex-military FEs, former mechs with A&Ps. These guys are usually permanent FEs, and they're worth their weight in gold on the flight deck.

I know they fly DC10s; I see them in ATL, BGR and LAS all the time. The Omni payscale is here on APC.
