Pension plans can be complicated things. Documented in thick manuals filled with arcane rules.

In the case of Continental Airlines’ pension plan, one such rule permits divorced, retired spouses to collect retirement benefits attributable to pilots still in active service.

Such pension benefits can amount to lump sums on the order of $1 million per spouse.

The airline has sued the nine pilots.
