I know of 2 F/o's having joined GF early 2003, were due to start up-grade this month or next, but were told that, late 2004. They have the time and license. Apparently they supercede 'senior' F/o's because of hrs and having an ATP, which others don't. Seniority, doesn't change, and reverts back to normal, when the 'senior' F/O, finally get's his Command, after he has the hrs and or the license. This is 767 fleet. Maybe I'm wrong.
