According to Spirit Airlines Corporate Investor Update dated October 15, 2015, Spirit Airlines  has updated its operating margin guidance for the third quarter 2015 to approximately 27 percent, up from our previous guidance range of 22.0 to 25.0 percent. The improved operating margin is driven by better-than-expected unit costs, as revenue for the quarter is in line with our previous guidance. 

In addition to fuel price declines, ex-fuel unit costs are expected to be lower than our previous guidance due in part to healthcare costs coming in lower than forecast and better than expected maintenance.

Question:  If our Healthcare costs came in lower than expected, why does the company want to gut the health insurance benefits for our Flight Attendant group?
