I think FLYCRJ200 has a subject worthy of discussion.

"Delta's Plan: Shrink both Comair and Mesaba and merge them."

If you read the mergers or majors thread, the "Seniority intergration trauma" - basing, aircraft assignment, lines flown, downgrades, pay, etc., etc. are big headaches. Why would Delta management, Unions and Pilot groups want to increase their Excedrin consumption by repeating the process ? It's easier (for management) to just gradually "disolve" Comair.

Reading the "Comair Updates" thread makes one think the process has started.
