Comair is what it is because D.S. can't sleep at night if there is ANY reserve sitting at home doing nothing and still getting paid guarantee. As a result, planners and schedulers are forced to make things more complicated than they really are and the whole operation circles down the drain.
As far as staffing, I have got to believe that it would be worth our while to carry a "little extra fat" during the spring and summer months, especially with JFK/northeast so easily disturbed by weather and other abnormalities. Whether that leads to recalls is above my paygrade, but right now the math is not adding up.
