Depending on your disposition I suppose they could, however, our profession is in a constant state of change and the age 60 retirement age will probably be one of those changes.
To those who have no desire to be working after 60, if age 65 is approved you can always resign upon reaching 60 and live out your remaining years in bliss, unfortunately due to recent events some people will need to work the extra years to get financially back on track.
What can be said with certainty is that there is no way you are going to please everybody with this one.
Wow...since our profession is changing I guess we should accept a blatant money-grab by the older guys? Retiring at age 60 has been one of the few CONSTANTS in this profession. It's one of the reasons I got into it in the first place! To change it now alters the entire underpinnings of the career.
Your pie-in-the-sky solution of guys who want to retire at 60 just resigning won't work, as others have pointed out. When the retirement age goes to 65 so will the pensions. Right now guys get punished financially to retire before 60 (just ask a Delta guy who bailed early to get his lump-sum A-fund). Do you think that will magically change when the age is raised to 65?
Yes, some guys need to keep flying beyond 60 for financial reasons. But do you really want to force everyone else to pay for their misfortune and/or mistakes?
If you want to keep flying past 60 you can find a nice Part 91 job tooling around in a G-IV. It brings in the cash, which you need. But the pro-change guys don't want that. They want to continue to accrue vacation, a pension and sick time at their airline.
OK, then: the ICAO rule says at least one person must be under 60 in the cockpit. How about we make that the Captain? When you turn 60 you roll back to the bottom of the list and end up as an FO on the most junior equipment. You're still flying, and at your same airline. Who wouldn't like that deal? Oh, right - the greedy bastages that want to camp out in the left seat of a widebody for five more years.
You are correct in that there is no way you are going to please everybody on this one. But since when is everyone pleased in this job?
