If they were to ever increase the age again there needs to be some type of phase in process. That last deal of adding five years with immediate effect harmed one generation of pilots while aiding another.
A personal example being that our family spent the five additional career years at the Regional FO wage, while another family spent the five additional years at top-end Mainline pay. That's why I could not previously support the push for age 65. Without a slow transition to any new rule (age, based on medical, etc.) keeping some movement alive in the industry, too many suffer all at once while others gain.
The true winners the last time were the airlines, and they wasted those years seeking concessions and kicking the can on making the industry desireable.
