“Expiration” of the flat dollar amount is due to IRS and/or ERISA regulation (forget exactly). Without a successor CBA at year end 10 years after going into effect (ie. 31 Dec 26 following CBA effectivity on 1 Sept 16), DB benefit reverts to contractual FAE.

As I posted upthread, matching your current $130k @ 25 YOS max defined benefit would require $5200 per YOS. This type of retirement could provide some funding relief to FDX, while providing a means for higher benefit via negotiation of a higher YOS rate or a YOS cap higher than 25.

Also, I understand one need only fly one revenue flight as CA to earn CA retirement at UPS; you don’t need to be a CA at retirement. There’s some former 727 and DC8 CAs who are now very senior PFOs who will get a CA retirement benefit when they punch.
