Every current multi-fleet airline in the US has different rates for different planes except for UPS I believe. JetBlue has different rates for different planes (except the 321) because it is industry standard. When JetBlue/B6ALPA negotiated rates for each of their planes, they did so using rates of every other major airline. If you guys get 190/195/220s or whatever new plane, you should negotiate whatever rate you can. If it’s the same as your 737 rate, great. And I never said you should buy scope with anything. But you should have negotiated it long ago. Scope and pay rates are two separate parts of a CBA. Negotiate each however you can to suit your pilot group.

Now, if I had a choice of my airline flying A220s at $10/hr less than 320 rates, vs a regional flying e175s/e190s/a220s for my airline instead, I would take the industry standard $10 lower A220 rates over the outsourcing every time. If you call that buying scope, well, ok. Also, Delta has different rates for their A223-($269) / A319-($274) / B737-700 ($284). But the planes are all roughly the same capacity and capability. You can argue the merits of a singular rate (I’ll probably agree with you for most of it), but my whole point by jumping in this thread isn’t to debate that point, it’s to refute your statement that a lower pay scale for different equipment is a B scale. B scales don’t exist anymore.
