PC767, They have just changed the requirement so that main crew can apply if they have had any people management skill at any time in the past not just the last six years. So it has opened up to many more main crew now.( check your emails)
This role is more like a CSD role and you have never before been able to go from main crew to CSD. You always have needed to be a Purser first. So being able to get this job from main crew directly is a really good move for some crew but as before you do need to be able to demonstrate people management skills.
I am sure that thoes that do not have people management skills would get promoted very quickly if they took the gamble and went for the Crew talent position as this fleet will expand rapidly at first. Those in at the start will I am sure do well.
