What if....
Consider this before signing.
The AOA and the company come to an agreement on this, let just for arguments sake say full credit for PX.
BUT then CX claims it doesn't apply to the guys who already agreed to PXing on the freighter, they signed an agreement. So now you are still stuck with .5 factor for PX while the rest will have 1 to 1.
How would you feel then.
It might not be credit factor, it could be anything else, but surely you can imagine CX saying it only applies to whoever didn't agree in the first place
