Earnings on the "low end" of guidance.

04:45 PM EDT, 07/18/2016 (MT Newswires) -- Shares of Spirit Airlines (SAVE) were slumping after hours Monday after the low-fare airline company said it expects Q2 total revenue per available seat mile at the low end of a previously provided guidance range.

The company also estimates Q2 operating margin of 22%, in line with its prior guidance, and estimates a "modest" quarter-to-quarter sequential decline in non-ticket revenue per passenger flight segment, ending Q2 with $51.32 in non-ticket revenue per PFS.

Spirit Airlines also forecasts Q2 adjusted cost per available seat mile excluding fuel to have decreased 8% year-over-year, compared to a prior guidance for a decrease of 5%. The company said the better-than-expected unit cost performance was mostly driven by the timing of maintenance events.
