Good post.
However, it is likely that recapturing compass could result in a BENEFIT to the pay of the Captains. Unions increase their bargaining power by the number of pilots and percentage of flying they represent.
Delta leaves money at the gate every time a 90 seat jet leaves the gate with less than 90 people on board. Certainly those 16 seats would have some revenue that would pay a mainline crew.
... and we need to add $1 an hour for the 737's Captains who take the "I've got mine, screw everyone else..." approach to scope. They too, need to see the BENEFIT to unity.
