Hawaiian Airlines' net income for the first three months of the year jumped to seven-point-three million US dollars compared to less than one million the same period last year.
Its CEO Mark Dunkerley told a conference call with investors the results were better than the company expected at the beginning of the year.
He says the company was able to fill a larger share of seats on its planes even as it expanded capacity.
Hawaiian reported operating revenue of 435.5 million, up from 365.5 million during the first quarter of last year.
Mr Dunkerley says the airline will continue to diversify its revenue base by growing into international markets as well as growing its domestic business to maintain its strength there.
