Hawaiian Airlines’ net income nearly doubled in the third quarter as lower fuel prices and strong passenger demand helped make up for increased competition on West Coast-Hawaii routes as well as a strong U.S. dollar that made it more expensive for some international visitors to fly. 

The parent of the state’s largest carrier, Hawaiian Holdings Inc., said today it earned $70 million, or $1.15 a share, compared with $35.6 million, or 56 cents a share, in the year-earlier period. Revenue, though, slipped 1.2 percent to $631.7 million from $639.5 million. 

Aircraft fuel, including taxes and delivery, fell 42.1 percent to $105.5 million from $182.2 million.
