Actually you are incorrect. In a CBA the collective very much DOES have that right, directly and indirectly. We happen to work under a very productive CBA (irrespective of the company's massive fleet diversity plan, which is 100% on them and not us). But to say you have some sort of a "right" in a CBA to FAR only limits isn't correct.

CBA maximums drive staffing, QOL and pay issues for the entire pilot group. The current system is extremely generous in what it allows for flying a lot if that's what you want to do. But there is no inherent right to fly FAR max all the time, and that's something that will never happen here outside of some deep chapter 11 on the verge of chapter 7 scenario. The limits we have are there for a reason, and part of why you make what you make and can hold what you hold. Its also why most pilots here were hired whenever they were.

Be careful what you wish for, and realize the limits of what you try and demand.
