One consideration for your upcoming negotiations. Delta’s profit sharing is based purely on the pretax profit of the airline. UAL’s PS is based on the profit margin of the airline. Currently given a equal profit it produces a similar PS check. 15 years from now however if each airline is still producing the same margin but revenues have doubled Delta’s profit sharing will have more than doubled given the 20% above 2.5 billion while UAL PS checks will remain the same. Consider trying to change the metric to capture growth!
