Given that Sen Graham is already rounding up support for an age change, I'm guessing that it will change in 2023 and there's nothing we can do to stop it. I know that's not what people want to read, but given how much opposition there was to 65 and we couldn't stop that (that also happened pretty quickly once Congress got involved), I am bracing for a couple of years of very little movement on the seniority list. The good thing is that 65 is an easier time for pilots to retire since they'll be immediately eligible for medicare - that should get a reasonable percentage to retire.
