I don't think their expectations are unrealistic if we, as a pilot group, can increase efficiencies and cost savings initiatives.
I don't really see anything more we as a pilot group can do to increase efficiencies...we're pretty much already doing it. Firing a bunch of redundant, useless middle manager types over in the headquarters building would be a good start toward saving money...but that's above our pay-grade.
Our performance has a lot less to do with the way we operate the airplanes and more to do with: the ramp (which sucks), gate agents(which suck), crew utilization (which sucks), maintenance (which sucks) and catering/cleaning/servicing (which mostly sucks).
I often feel like Delta is purposefully sabotaging our performance...
