The real reason that most pilots here want the age 60 rule to stay in place is because they think that they can move up the seniority ladder or get recalled from furlough faster. It's just a way to get rid of the senior pilots. The age 60 rule, when conceived, had nothing to do with health considerations.
But those senior pilots got to move up faster because the rule existed. Now many of them are crying about how unfair it is. Yes it is unfair, it was when they were in their 30s and 40s too
Those last 5 years at your company will be the most productive years most likely so what's wrong with allowing me to have 5 more?
Because then my last 5 years will start later, so if I chose to quit at 60 I'll miss out on my 5 most productive years. So the guys that are senior when the rule changes get 10 years while everyone else gets 5 (your numbers).
It's simple...if you don't want to work past age 60 then don't. If you don't trust my health at age 63 then don't fly on my flight. You are free to get off although I'm willing to bet you wouldn't.
It IS simple, the age 60 rule was in place when you were junior, now you are senior and you want to stay in my seat as long as you can. You accuse junior folks of being greedy, but clearly you have a lot to gain if the rule goes away.
