If they want 777 pilots to transfer, they get 777 pilots, even if they have to draft them.
Yes it's unfair to the 330/340 pilots, but if you want to go and don't, all you are doing is meaning they will NOW be unfair to a junior 777 pilot that doesn't want to transfer.
If NOT going helped out the likes of airbus girl, I wouldn't even think of it (I'm not anyway!!) but unfortunately it doesn't.
