FIRE for pilots

I'm curious if anyone has experience trying to reach FIRE as a pilot. It seems like a difficult career to retire early from because it take such a long time to get to a high salary. But on the other hand it seems like if you get enough seniority at the right company you can get a lot of control over your schedule and semi retire, or am I totally off with this assumption? Is part 121 or 135 better for early retirement? I'm currently just a private pilot with a full time job and I plan on accumulating all the ASEL ratings gradually over the next few years. From a purely financial perspective it's a terrible idea for me to switch careers, but I love to fly.
