This is a likely scenario as it would open a rare opportunity to get upgraded. I work in an environment where there are no upgrades, because they just don't happen.
Almost every airline in the world which hires DECs has one identical requirement these days: a minimum of 500 hours in command o n t y p e. This renders any number of hours as a First Officer and even command hours on another type completely useless. As far as I know this requirement is not based on any law, it just saves training costs. Simply put, this is a discrimination which is unheard of. Alas it is not on the "agenda" of the ALPAs to change this situation. That leaves me with a prospect of exactly zero until I retire. And it supports the notion maybe every business has, but the aviation business has it in a very special way: it's not about what you can, what you know or what your experience is. It's just about whom you know!
Now you can blame the victim.
