Spirit Airlines Reports August 2012 Traffic

Miramar, Florida (September 13, 2012) – Spirit Airlines (NASDAQ: SAVE) today reported its preliminary traffic results for August 2012 and year-to-date 2012.

Traffic (revenue passenger miles) in August 2012 increased 18.9 percent versus August 2011 on a capacity (available seat miles) increase of 20.5 percent. Load factor for August 2012 was 86.5 percent, a decrease of 1.2 points as compared to August 2011.

As previously disclosed, the Company’s total revenue per available seat mile (“RASM”) in the third quarter of 2011 was 28.4 percent higher year-over-year in large part driven by a demand increase resulting from the Company’s decision to pass on to its customers the full amount of the benefit realized from the federal excise tax (“FET”) holiday. “The FET holiday effect in third quarter 2011, coupled with the revenue impact in the current quarter of Hurricane Isaac, leads us to expect that our third quarter 2012 total RASM will be down 2.5 to 4.5 percent year-over-year,” commented Ben Baldanza, Spirit’s President and Chief Executive Office. “But for these unusual items, we estimate our third quarter 2012 total RASM would have been up year-over-year which makes us comfortable with our organic revenue growth trend and we remain confident in our ability to leverage our low cost structure to profitability grow our business.”
