There is a reason you should keep your salary secret, because even for big corp salary is more based on your ability to negotiate, value of your talents, and the company think you're easily replaceable or not. At a very young age I built the network infrastructure for a corporation, although technically I'm just a law "level-2 network engineer", but I managed to negotiate my salary to that 3 times what others in my level are making, simply because I know that they know that if I walk right then they will have no one to run it with any intelligence.

I would imagine CX management to be the same. Those "value managers" that brings to the table that no one else can will get pay a whole lot more than other managers that are there to do important tasks, but are easily replaceable if they should walk to take another job.

Pilot salary is different, since they are union so pays are strictly based on pre-negotiated ranking and not on merit. Which is why I believe for uniquely talented individuals that brings a set of skills that no one else has, union would be a nightmare for him.
