The parent company of Hawaiian Airlines said its earnings fell nearly 70 percent in the third quarter due in part to expenses related to fuel hedging contracts and an increase in the company's tax provision.

Hawaiian Holdings Inc. reported net income of $6 million, or 12 cents a share for the three months ending Sept. 30, down from $19.6 million, or 41 cents a share during the same quarter a year earlier.

On an operating basis, revenue increased 24.7 percent to $339.9 million during the third quarter from the year-earlier period. Operating income rose 6.9 percent to $27.3 million.

Revenue per available seat mile rose 23 percent to 13.92 cents, while passenger yield increased 34.2 percent to 15.95 cents, the airlines reported.
