the prospect of a relatively quick command at or before the age of 30, would certainly make me want to stay.
If you say this then I don't think that you've been at Easy for long (not having a permanent contract as you state, is a clue.)
As a CTC cadet in your early 20's, year 1 at Easy is great fun.
Year 2 is also good.
Year 3 you're starting to get a little hacked off with things.
Year 4 you start to consider leaving but are unsure as command might be coming up.
Year 5 you now want to leave but have a command course planned.
Year 6 you turn down that chance to join other Airlines to pass your command course.
So now a Year 1 Captain and the extra money is great.
Year 2 Captain and the gained experience settles you nicely into the job.
Year 3 Captain and...............................then what?
30 years old, Captain, good income
but another 35 years until retirement with Easyjet? Thats a really tough call.
Personally, I don't think anyone could stay for a whole career here the way things are at the moment.
I only hope that 'uSay' is taken seriously by the new management for these hopes and aspirations to become reality.
