I can say that some of us, without management, have taken it upon ourselves to slowdown, we still get there on time, just with a little more fuel. We figure it is a good thing to do, kind of like job preservation. If we help with the fuel we may avoid down sizing.
Now I fly a turbo-prop and our legs are short and over-blocked so it makes it easier to stay on schedule while not pushing the engines. It's not a huge difference only about 100-200 lbs per leg of savings, but like the govt says "a billion here, a billion there before you know it, you are taking real money"
