ALV isn't tied to minimum guarantee in JetBlue's contract. It's possible even under current book to be awarded less than minimum guarantee when the ALV is low, as it has been for the last few months. If that happens, you're immediately awarded enough credit to bring you up to minimum guarantee, then you can pick up or trade over that. If the LOA includes lower ALV to award more lines at lower values, then everyone still gets at least minimum guarantee right out of the gate. I suppose that would upset those pilots who bid maximum credit (since they'd have to work and/or bot harder to pad their lines) but it doesn't damage the pilot group or contract integrity. Maybe I'm missing something but I'm not detecting the slippery slope here.
