The airline says it would have earned $192 million, or 98 cents per share, before gains such as a swap of airport landing slots with Delta Air Lines.
Analysts were expecting 92 cents per share excluding one-time items.
Revenue rose 3 percent to $3.53 billion but fell short of analysts' expectations of $3.55 billion.
CEO Doug Parker says the revenue environment remains strong. Travel demand has been strong enough to allow airlines to raise prices about a dozen times since the start of 2011.
