Commenting on the results, CEO Ben Baldanza said in a press release:

What went right:Gross margin improved from 33% in last year's Q2 to 39.9% over the past three months as Spirit kept a lid on costs and optimized revenue while expanding. Specifically, the carrier added three new A320 aircraft and 24 new nonstop routes in the second quarter. A 17.4% drop in the price of fuel no doubt contributed to the gains.

What went wrong:Spirit didn't fill up its new routes as fast as investors expected. Available seat miles jumped 30.1% but revenue passenger miles -- the amount actually alloted for ferrying travelers -- rose 27.8%. Load factor dipped 1.5 percentage points.The good news? None of this had a meaningful impact on cash flow from operations, which has more than doubled year over year through the first six months of 2015.

What's next:Spirit Airlines didn't include a third-quarter outlook in its press release. Nevertheless, analysts tracked by S&P Capital IQ have the company generating $580.88 million in revenue and $1.18 a share in profit after accounting for stock-based compensation and other noncash items. That compares with $519.80 million and $1.01 a share in last year's Q3.

Longer term, analysts have Spirit growing earnings by an average of 20.27%annuallyover the next three to five years.

In the meantime, investors should pay close attention to the delta between revenue per available seat miile and cost per available seat mile as capacity increases and the fleet shifts. Maintaining a healthy gap as Spirit modernizes is key to sustainable profit.
