The last time there were mass bankruptcies that caused pilot groups to lose their defined benefit pensions, practically none also had a defined contribution plan.

Losing the DB meant they lost all their retirement income.

UPS and FDX pilots both currently have diversified retirement income from both DB and DC plans, providing a level of risk mitigation that didn’t exist for many (most) legacy pilots in the early 2000s.

Put another way, it’d be ignorant to think pilots that still have DB plans today did not, as a whole, learn any financial lessons from the post-9/11 bankruptcy era.
