To one of the scope numbers experts:

How close is our mainline fleet to the number where an increase of one mainline jet allows three additional RJs? If they keep the 9's here to overlap with the -900 deliveries, could it push us over the threshold? Scary thought when you think about adding 200-300 RJs since that number does not go back down when they do park the 9's. Could that be part of the push for a contract extension? Keeps the current (ridiculous) scope clause in effect long enough for them to take advantage of it?
