A friend of mine, who declined a legacy for Fedex, explained to me this hub turn thing they do. Does not sound fun at all.
I have yet to see a redeye that wasn't oversold or damn near close to it. I am sure there are some, but when I've flown them, or non rev'd on them, they've all been pretty damn close to if not completely full.....so I guess it's good for the PS checks.
