In the APA PEB the peer group for comparisons was for comparable airlines. Even though we work on the same planes, the companies provide different services and therefore different business models. It has nothing to do with the work.
That PEB was under Clinton, in the AMTRAK PEB the company tried to say that the frieght rails should be excludede but the Bush PEB includede them anyway citing that historically the contracts followed each other.
The fact is it is the work, not the business model. We sell A&P labor on heavy turbine aircraft, Does Exxon alter the price oif fuel based upon the business model or profitability of the consumer?
