That's true, but nearly every FO in LHR is senior to the KA 747 CNs in MAN. You think senior LHR crew are going to jerk gear for junior captains on the pax fleet? I don't. It happens on the freighter, but that system is dying on the vine and will be rectified over the next decade.
If July 2008 hires are in the 777 left seat out of LHR, CXC will be burnt to the ground.
