To me, I'mbatman gets it. Being JFK based, I am betting he will be converted to the 777 in the next couple years. When he is, he will be so glad he stood his ground on the freighter PXing. He will not be subject to ridiculous patterns on the 777F. Instead, he will be operating for much more credit whether it is on the passenger or freighter aircraft. Subsequently, he will very likely be at home more, not less.
8driver,
I get what you are writing about, but I think you are being somewhat shortsighted and naive. The only thing that is for sure is that things will change. When they do, I'm sure you will still be able to give away your rights not to PX on the freighter. "One time opportunities" at CX which primarily benefit the company tend to be available after the "deadline" expires (ie CoS08).
