Item 7.01
Regulation FD
The information in this report furnished pursuant to Item 7.01 shall not be deemed “filed” for the purposes of Section 18 of the Securities and Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section. It may only be incorporated by reference in another filing under the Exchange Act or the Securities Act of 1933, as amended, if such subsequent filing specifically references the information furnished pursuant to Item 7.01 of this report.
Spirit Airlines, Inc. (Spirit), is scheduled to present today at the J.P. Morgan Aviation, Transportation and Industrials Conference and is providing the following updated revenue guidance:

The Company estimates that its first quarter 2017 total revenue per available seat mile (TRASM) will be down 4 to 5 percent year over year.  Previously we had estimated our first quarter TRASM would be down approximately 2.5 percent year over year.   We believe this revision is largely due to our underestimating the impact related to the Easter holiday shift.  Based on current bookings, we are encouraged by the second quarter revenue trends and continue to believe TRASM for the second quarter will be positive year over year.
