A show of hands, who here has asked a FA or your seatmate out?
I usually wait until the seatbelt signs is off before I play musical chair.
I have been lucky on those CRJs as I was flying EWR-YOW and while boarding I noticed this beautiful woman behind me and I tried to make eye contact but she wasn't into it. I sat down and thinking how much work I have to do after the meeting, next thing I looked up and there she was walking down the aisle looking for her seat. I thought to myself, please, oh, please, sit next to me. And she did.

We chatted the whole way and I even got her phone number, and its REAL. Too bad we live in different cities. That has happened to me only once.
I also think you SE are shortchanged because >80 % of passengers sitting in front cabin are older men. So at least our chances are better in Y.
