Michael, for arguments sake, let's say Virgin America was ALPA. Your using a "relative seniority" argument.....The senior most Virgin America pilot has what....1-2 years with the company....Where would he go in your version of a "fair" list if Delta and Virgin America merged?
You know very well that ALPA merger policy takes career expectations into account while prohibiting windfalls for either side. In the case of a legacy merger with a carrier like Virgin America, a ratio wouldn't be a fair integration. You have to look at each situation individually. Simply demanding DOH for all situations is absurd.
