We'll see whether US can keep up the on-time stats once the fat is removed from the schedules:
After last summer's debacle, US Airways did move to cut flights to build more cushion into its schedule, slimming down in the peak hours and holding a couple more planes back to use as spares. More minutes were added to some trips to more realistically reflect airport delays and congestion.
With things going better, US Airways is moving back to cost-savings moves to "optimize" its schedule, taking some of the cushion out of the schedule that was dropped in last year, because the airline thinks it's no longer needed.
As US admitted a few weeks ago, buying that schedule reliability is very expensive. If the employees can keep it up once the schedules are trimmed,
that will be a real accomplishment.
