wouldn't surprise me if we saw a good number of new hire slots going to the 756 over then coming months, as they have been making sure they keep the current pilots in the fleet during the transition from 76T to 756.
So, I believe there are a good number of 767 First Officers (whether 756 or 76t) that are waiting for training out of the fleet going up to the 777,787,747 or even Cap seats.
