...and the bit about 4 year upgrades on 777.
The guys upgrading on 777 now joined 4 years 9 months ago. The upgrade times are going to increase significantly from now on. If you joined the 777 fleet now, you would have over 1100 F/Os ahead of you. Are they really going to upgrade almost 300 F/Os a year just on the 777 fleet?
And then there are the 100 or so DECs every few years...
