The "whip saw" theory is interesting and can be viewed in a number of ways.

Local 357 has stated their goal as Jet Blue rates, this establishes an expectation among the pilot group.

Jet Blue only has 190's, no 135/145/170/175's. IF you're able to get Jet Blue rates on the 190's, what is the goal for all the other aircraft rates?

What "peer group" will 357 use for the smaller aircraft, I believe the majority of your most senior pilots are on the 135/145 (not that I have to ask, but if that's incorrect, please correct me).

So now are the different aircraft types pay rates within native RAH being "whip sawed" internally?
