Appears there are 2 bonuses. One for customer satisfaction survey results. The on-time bonus is baffling...UA just has to finish in the top half of the legacy carriers (first or second). Not sure why this wouldn't be tied to a percentage, perhaps adjusted for WX events so that it was fair to employees.

I agree. But not sure I'd link it to a low on-time percentage which is, to some extent, out of the control of front line employees. I like the bonus tied to customer satisfaction.
