Item 7.01    Regulation FD Disclosure.

On September 7, 2016, Southwest Airlines Co. (the "Company") issued a press release announcing its traffic results for August 2016. The press release is furnished herewith as Exhibit 99.1 and is incorporated by reference into this Item 7.01.

Tammy Romo, Executive Vice President and Chief Financial Officer of the Company, is scheduled to present on September 7, 2016 at the Cowen and Company 9th Annual Global Transportation Conference. An audio webcast of Ms. Romo’s remarks will be available on the Company’s Investor Relations website at, in the Events & Presentations section. The Company is providing the following guidance regarding its financial and operational trends:

Based on current booking and revenue trends, the Company continues to expect its third quarter 2016 operating revenue per available seat mile (RASM) to decline in the 3.5 to 4.5 percent range, as compared with third quarter 2015, with approximately 0.5 point of the decline resulting from the Company’s July 2016 technology outage.
Based on current cost trends and excluding fuel and oil expense, special items, and profitsharing expense, the Company continues to expect its third quarter 2016 unit costs to increase in the 3.0 to 4.0 percent range, as compared with third quarter 2015, including the impact from the July 2016 technology outage1.
Based on the Company’s fuel derivative contracts and market prices as of September 2, 2016, the Company continues to expect its third quarter 2016 economic fuel costs to be approximately $2.05 per gallon, compared with third quarter 2015’s $2.20 per gallon1.
The Company continues to expect its full year 2016 available seat miles (capacity) to increase in the 5.0 to 6.0 percent range, year-over-year.
The Company expects its full year 2017 capacity to increase less than 4.0 percent, year-over-year, with approximately 2.0 points of the increase relating to domestic growth and 1.0 to 2.0 points relating to international growth.

A replay of the audio webcast of Ms. Romo’s remarks will be available on the Company’s website at, in the Events & Presentations section under Past Events and Related Presentations.

The information furnished in this Item 7.01 shall not be deemed "filed" for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that section, nor shall such information be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, regardless of any general incorporation language in such filing, except as shall be expressly set forth by specific reference in such filing.

1Projected results do not reflect the potential impact of special items, or fuel and oil expenses and profitsharing expense, where indicated, and the tax effect of all such items because the Company cannot reliably predict or estimate those items or expenses or their impact to its financial statements. Accordingly, a reconciliation of non-GAAP financial measures to the equivalent GAAP financial measures for projected results is not available without unreasonable effort.
