When all of us, including the NDs were hired...Your "pilot" seniority number expired at age 60. About 150 of our ND's had expired pilot seniority numbers. They were using Flt. Engineer seniority numbers, literally(most of which didn't match their old PILOT seniority numbers). Our MEC pressed to have those guys given their pilot seniority numbers back. Had they not pressed for retro, they still would not have pilot seniority numbers. Their "regulated age" still would have been age 60. Those age 60, after the change, would have had a regulated age of 65. Just as any UAL, DAL, CAL, etc. pilot that turned age 60 on Dec 12, had a regulated age of 60. A guy born a day later, has a regulated age of 65.

Of course, we all know that. And, it's water under the bridge. It just seems that the tide keeps bringing it back upstream, sometimes.
