Damn near anyone that's over 55 has been here for a long long long ass time. Unless they have multiple ex wives or are complete morons with their money every single one of them can retire if this place closes.
Hell I left after 3 years and 4 months as an FO with $33k in my 401. Your talking about guys who make $100+ (nearly mainline FO pay) as CAs on the Bach Jet, some for years on end.
The people who are gonna get Fd are the late 30s thru early 50s crowd.
