Within months of retirement so I have no dog in this fight.

You guys are spending a lot of time targeting Congress. The FAA Administrator can simply change the retirement age, which is the course of action I'd expect at this point. Why? Because there's not enough opposition to that happening and he could make the change without much debate. There'd likely be a NPRM, which would allow public comments - I think the window's something like 60 days on comments.
BUT Bedford isn't going to do that until ICAO goes to 67. And neither will Congress change it until ICAO makes the change.
It could change as early as 2026, but my guess would be 2027 or 2028.

It will eventually go to 67, and then age 70 a decade or two after the change to 67. The problem is that once the age changed from 60 to 65, the door opened for further changes.

,,, just my uninformed opinion.
