That would require staff to conduct said evaluations, gather the data, compile it, etc.

Not to mention, most airline folks aren't too keen on spending time they're not getting paid for, for writing out evals on pilots they interacted with who knows when. With the volume of pilots that employees interact with, it can be hard to remember who was who! It's possible that you can fly with half dozen pilots during the course of a 4-day trip.

The idea of performance reviews is great in a corporate world where you see and work with the same people day-in-day-out. The airline world is very different. You can fly with someone, and literally never see them again. Ever!

The senority system is not perfect, but like everyone else has said, there's yet to be a merit/performance based system that would work well (notice I said well) with crew memebers!

This very topic was discussed on F/A.org a while ago. Someone who is with an airline based in Dubai started it, and he was gloating about how he kisses butt and gets rewarded for it. Basically everyone told him "that's nice, but instead of kissing managment's rear end, and worrying about performance appraisals, I'd rather put my energy into doing a good job".
