Hawaiian Airlines said Tuesday that cost control and its domestic operations helped narrow its loss to $5.1 million in the seasonally weak first quarter.

In the year-earlier period, the state’s largest carrier lost $17.1 million.

Hawaiian, which added a turboprop operation in March to Molokai and Lanai, said its revenue during the quarter rose 6.9 percent to $524.9 million from $490.8 million.

Its loss per share during the January to March period was 10 cents compared with a loss of 33 cents a share in the first quarter of 2013.

Hawaiian President and CEO Mark Dunkerley said unfavorable exchange rate changes weighed on the airline’s international business.
