All the talk about restoring retirement to 60% FAE, the PBGC would consider that a "follow-on plan" which it considers "abusive" to the insurance program.

What do you think the chances are that Delta would agree to any of that in a new contract? http://www.pbgc.gov/documents/lfad/ltv-restoration.pdf
