What about the prevailing thought that many pay rates offers protections in the event of a disparate merger? For example, say a hypothetical narrow body LCC (or a portion thereof)? Some people with their ears to the train tracks are of the opinion that more consolidation is coming and if so, that's where it will happen.

If having one rate made a large legacy airline even a little more vulnerable to a full relative fleecing from a narrow body LCC, that would obviously make it a complete nonstarter.
