While 67 is a congressional push, because, I think a function of CEOs lobbing them to provide an answer to poor leadership and planning, it can not happen until we all agree on it. ICAO and EASA along with the UK CAA will be required to have the same ages. 65 is the current age in all those governing authorities and by that an airline can not allow anyone older to fly a Part 121 aircraft in those regulatory airspaces. When 65 went in to law we were behind and the FAA stopped pilots from other country airlines from flying into the National Air Space because we did not allow it as soon as they did. This is a pie in the sky view of a congressional and CEO wish list, but it will not happen soon. This is a 3-4 year proposition, the FAA has been working on a BASA SIP with EASA for A and P Mechanics for 6 years and are no where close, now try and get them to change a limit! I would say most of us will be gone by then.
