A few thoughts...

This might shine a light on the FAA medical process that might not be ideal for a lot of people. Be careful what you wish for...

Returnees are getting stapled to the bottom for sure.

If this thing passes, I seriously doubt ICAO will just immediately follow in lockstep like everyone seems to arrogantly think they will. We ****ed away a lot of that clout with the MAX debacle. A change would require a very hard diplomatic push from the Biden Administration, plus most international carriers aren't pushing for this, neither are other countries. ICAO member states aren't exactly breaking their neck in a rush to appease reps from backwater flyover states in rural America without the approval of POTUS.

And if they did, the rules for international operations would have a lot more strings attached. Possibly relegating 65+ to SIC only, or even IRO only. Or maybe even put even more restrictions on the 60+ pilots. Which personally I'd be fine with.
