When a flexi line pilot can earn more for the same number of hours as a full time pilot, it doesn't meet my definition of B scale.
Unfortunately that works both ways, waren. They "CAN" earn more. Until the company don't feel so inclined, in which case they no longer "CAN". At that time, they "CAN'T".
You might not call it a "B" scale all of the time. But it is most definitely a significantly "eroded" scale. And it has the capacity to be a "Z" scale.
