FO Seat lock
It doesn't take much to "delay" upgrades without that word "seat lock", but the truth is about to hit that any outside DEC is now going to come from a non-NG or non-737 type!!!! So you will need a completely new formula to work out the upgrade for existing FOs! Who do you think will be the real insight into KTM or KBL or Russia in the winter? I would stab a guess at 2years right now and when you factor in the quiv 3000hrs or max 5yrs at EK then it holds no comparison! The FOs will leave much quicker than the capts! It's actually more beneficial to fly capt with capt than lose the knowledge of good guys! Let's see! We have reached the 2yr point and will start to see people migrate as they start interviews with other ME carriers now that their poaching period has expired!!!!
