Leine,
You bring up some very good points. My criteria for improving Scope is simple (the following numbers are notional): If for example we currently fly 65% of the passengers who purchase a DAL ticket and after the upcoming contract we will improve to say 70% or 75% with locked in minimums then we have improved Scope. Could this happen with more 76 seaters - yes.
The more passengers that fly on DAL metal - the quicker the stagnation will end. While it especially burns me to see DCI flying so many of our passengers to some very big cities, in reality it is really no different than Alaska or Air France, etc flying our passengers.
George is really the guy who can shed some light on the top end scope - he is normally all over it.
