Fourth Quarter 2012 Guidance

The Company estimates its total revenue per ASM (RASM) for the fourth quarter 2012 decreased 7 to 8 percent year-over-year.

Hurricane Sandy reduced fourth quarter revenue by approximately $25 million and reduced total RASM year-over-year by approximately 6.5 percentage points. The revenue impact from Hurricane Sandy was less than previously estimated primarily due to a stronger-than-anticipated recovery in demand for the month of December.

The Company's fourth quarter 2012 cost per available seat mile (CASM), excluding special items and unrealized mark-to-market hedge gains, is estimated to be between 10.00 cents and 10.05 cents. Spirit estimates its CASM ex-fuel for the quarter was between 5.90 cents and 5.95 cents, which is in line with the Company's previous guidance.
