That few appears at least from my experiences to be "quite a few". In the jump-seat headed up north one night a moderately senior captain says " If this company purchased 737's and wanted to pay me $1 an hour more I'd do it in a heartbeat! Because #1 is all that matters, and I'm #1. Just looking out for myself." The fairly junior F.O. found this to be a really good philosophy and continued to kiss the guy's a**. Take it for what it's worth but I couldn't tell it any more accurately. And I've heard and seen similar things on several occasions.

This seems to coincide with the folks that say "hey did you hear? We're getting more 90 seaters!" Um, didn't even know we had "90 seaters". Never mind more, but ok.......
