"I’m happy to report the second quarter of 2019 was Allegiant’s 66th consecutive profitable quarter," stated Maurice J. Gallagher, Jr., chairman and CEO of Allegiant Travel Company. "We commented last quarter about the benefits of our all Airbus fleet. These benefits are continuing and increasing. We led the industry in Q1 with a 22 percent airline operating margin; this quarter the airline generated a 24 percent operating margin, a six percentage point increase from the previous year. And we accomplished these results with seven fewer aircraft this year compared to 2018. The fuel efficiencies of the Airbus continue to impress. We consumed 4.9 percent more fuel in Q2 compared to last year but produced 13.4 percent more ASMs. Correspondingly, our CASM ex-fuel declined 6.1 percent year over year. I’m comfortable stating we believe we will be the only carrier this quarter who had lower unit costs this year versus last year.

"On the revenue front, scheduled service revenue was $11 million per aircraft during the first six months of the year, over $2 million more than last year’s per aircraft revenue during the same period. Additionally, we generated approximately $3.5 million of EBITDA per aircraft in the same period or about $1.1 million greater per aircraft than the same period last year.

"Our operations continue to excel. We have solely led or tied for the industry lead in completion factor every month in 2019.  One of our challenges in the past few years has been our ability to scale our operations during our peak periods in the summer months and maintain a high completion rate.  In June 2018, we were number five in completion rate; this year we were number one. I’m happy to report we have had only ten days where we have had a mechanical cancellation since the beginning of the year.

"This combination of superior financial results and industry-leading operational performance, along with the proprietary model we have developed and continue to operate is a tribute to our excellent team members. Looking forward, we are excited about the opportunities in front of us including our ability to operate our leisure model to Mexico and the Caribbean in the coming years."

Appendix A
Non-GAAP Presentations
Three and Six Months Ended June 30, 2019 and 2018
(Unaudited)

Airline operating revenue, airline operating income, airline net income, airline operating expense, and airline diluted earnings per share all eliminate the effects of non-airline operating activity, which is not reflective of the airline operating performance. Airline earnings before interest, taxes, depreciation and amortization ("Airline EBITDA") eliminates the effects of non-airline operating activity and other items. As such, all of these are non-GAAP financial measures. We believe the presentation of these measures is relevant and useful for investors because it allows them to better gauge the performance of the airline and to compare our results to other airlines.

The SEC has adopted rules (Regulation G) regulating the use of non-GAAP financial measures. Because of our use of non-GAAP financial measures in this press release to supplement our consolidated financial statements presented on a GAAP basis, Regulation G requires us to include in this press release a presentation of the most directly comparable GAAP measure, which is operating revenue, operating income, net income, operating expenses, and diluted earnings per share and a reconciliation of the non-GAAP measures to the most comparable GAAP measure. Our utilization of non-GAAP measurements is not meant to be considered in isolation or as a substitute for operating income, net income or other measures of financial performance prepared in accordance with GAAP. Our use of these non-GAAP measures may not be comparable to similarly titled measures employed by other companies in the airline and travel industry. The reconciliation of each of these measures to the most comparable GAAP measure for the periods is indicated below.
